瓦良格(諾斯)首領 Rurik 應斯拉夫人邀請來統治諾夫哥羅德，建立留里克王朝。其繼承者奧列格 882 年遷都基輔，Kievan Rus 國家成形。是俄羅斯國家紀年起點(862 = 俄羅斯紀元元年)。
Varangian (Norse) chief Rurik was invited by Slavs to rule Novgorod, founding the Rurik Dynasty. His successor Oleg moved the capital to Kiev in 882, establishing Kievan Rus. 862 is the conventional founding year of the Russian state.
從 Rurik 建國到蒙古滅基輔，Kievan Rus 持續 378 年，建立東斯拉夫文明根基：東正教、西里爾字母、商貿王國連接拜占庭與北歐。「俄羅斯」、「烏克蘭」、「白俄羅斯」皆出於此。
From Rurik's founding to the Mongol sack of Kiev, Kievan Rus lasted 378 years — laying foundations of East Slavic civilization: Orthodox Christianity, Cyrillic alphabet, a trading kingdom linking Byzantium and Scandinavia. Russia, Ukraine, and Belarus all trace origins here.
Kievan Rus 大公弗拉基米爾在 Korsun(克里米亞)受洗，迎拜占庭公主 Anna 為妻，全國改信東正教。從此俄羅斯文明根植於拜占庭傳統，與西方天主教世界分道揚鑣 1000 年。
Grand Prince Vladimir of Kievan Rus was baptized at Korsun (Crimea), married Byzantine princess Anna, and converted the whole nation to Orthodox Christianity. Russian civilization rooted in Byzantine tradition, diverging from Catholic West for 1,000 years.
11 世紀起諾夫哥羅德建立特殊體制，由市民會議(veche)選舉王公，是俄羅斯史上少見的「貴族共和」。漢薩同盟北端，與西歐貿易繁盛。1478 年被莫斯科伊凡三世吞併。
From the 11th century, Novgorod developed a unique system: the citizens' assembly (veche) elected the prince — a rare 'aristocratic republic' in Russian history. The northern terminus of the Hanseatic League with thriving Western trade. Annexed by Moscow's Ivan III in 1478.
雅羅斯拉夫即位基輔大公，編纂《羅斯法典》(Russkaya Pravda)首部成文法、興建聖索菲亞大教堂、與北歐法德王室聯姻(女兒安娜成法國王后)。Kievan Rus 文化、貿易、外交鼎盛期。
Yaroslav became Grand Prince of Kiev, codified the first Russian written law (Russkaya Pravda), built St. Sophia Cathedral, and married his daughters to European royalty (Anna became Queen of France). The peak of Kievan Rus culture, trade, and diplomacy.
12 月 6 日蒙古拔都汗(Batu)攻陷基輔，屠城。Kievan Rus 終結，俄羅斯諸公國臣服蒙古「金帳汗國」240 年(1240-1480)。經濟文化倒退、與西歐隔絕，奠定俄羅斯與歐洲不同的歷史軌跡。
On December 6, Mongol khan Batu sacked Kiev, massacring the city. Kievan Rus ended; Russian principalities became Mongol vassals under the 'Golden Horde' for 240 years (1240-1480). Economic and cultural regression, isolation from Western Europe — setting Russia's divergent path.
金帳汗國(Golden Horde)宗主俄羅斯諸公國，徵稅徵兵 240 年。莫斯科靠當蒙古的稅吏崛起，斯拉夫文明吸收蒙古行政、軍事元素，東正教因蒙古宗教寬容反而興盛(教會免稅)。
The Golden Horde was suzerain over Russian principalities for 240 years, collecting taxes and conscripts. Moscow rose by serving as Mongol tax collector. Slavic civilization absorbed Mongol administrative and military elements; Orthodox Christianity actually flourished (Church was tax-exempt under Mongol religious tolerance).
4 月 5 日諾夫哥羅德王公亞歷山大在楚德湖冰面擊退條頓騎士團西進。蒙古佔領下卻向東屈從、向西抵禦，被尊為俄羅斯民族英雄。1547 年封聖、1942 史達林設「亞歷山大涅夫斯基勳章」。
On April 5, Novgorod prince Alexander defeated the Teutonic Knights' eastern advance on the frozen Lake Peipus. Submitting to Mongols east, he resisted Westerners — becoming a Russian national hero. Canonized 1547; Stalin established the Order of Alexander Nevsky in 1942.
伊凡一世「錢袋子」即位莫斯科大公，以替蒙古收稅累積財富權勢。1326 年大主教遷莫斯科，使莫斯科取代弗拉基米爾、特維爾成東北羅斯宗教中心。莫斯科 200 年內統一俄羅斯起點。
Ivan I 'Kalita' (Moneybag) ascended as Grand Prince of Moscow, accumulating wealth and power as Mongol tax collector. In 1326 the Metropolitan moved to Moscow, displacing Vladimir and Tver as religious center of northeastern Rus — beginning Moscow's 200-year rise to unify Russia.
9 月 8 日莫斯科德米特里·頓斯科伊聯合俄羅斯諸公國於頓河源庫利科沃擊敗金帳汗國馬麥(Mamai)。蒙古不敗神話破滅，俄羅斯民族意識萌芽，雖之後仍臣服蒙古百年但精神獨立。
On September 8, Moscow's Dmitry Donskoy united Russian princes to defeat the Golden Horde's Mamai at Kulikovo Field on the upper Don. The Mongol invincibility myth shattered; Russian national consciousness emerged. Though Mongol rule continued for another century, the spirit was free.
伊凡三世「大帝」即位莫斯科大公，43 年內吞併諾夫哥羅德、特維爾，國土擴 3 倍、結束韃靼桎梏(1480)、娶拜占庭末公主索菲亞(1472)、改建克里姆林宮、提出「莫斯科第三羅馬」雛形。
Ivan III 'the Great' became Grand Prince of Moscow. In 43 years he annexed Novgorod and Tver (tripling territory), ended the Tatar Yoke (1480), married last Byzantine princess Sophia (1472), rebuilt the Kremlin, and seeded the 'Moscow as Third Rome' doctrine.
10-11 月伊凡三世與大帳阿合馬對峙於烏格拉河，雙方皆無攻而退。240 年韃靼桎梏正式終結，俄羅斯重獲獨立。伊凡三世自稱「全俄羅斯君主」，並娶拜占庭末代公主索菲亞，採用雙頭鷹徽號。
From October-November, Ivan III faced down Khan Akhmat at the Ugra River — both sides withdrew without combat. The 240-year Tatar Yoke formally ended; Russia regained independence. Ivan III titled himself 'Sovereign of All Russia' and married Sophia, the last Byzantine princess, adopting the double-headed eagle.
1 月 16 日 16 歲伊凡四世在莫斯科聖母升天大教堂加冕為「全俄羅斯沙皇」(Tsar = Caesar 拉丁文凱撒)。是首位正式沙皇，象徵俄羅斯繼承拜占庭(東羅馬)正統。後因恐怖統治得「雷帝」(Грозный)惡名。
On January 16, 16-year-old Ivan IV was crowned 'Tsar of All Russia' (Tsar = Latin Caesar) at Moscow's Dormition Cathedral. The first formal Tsar, symbolizing Russia's claim to Byzantine (Eastern Roman) legitimacy. His brutal reign earned him 'Grozny' (the Terrible).
1598-1613 年留里克王朝末代沙皇費奧多爾駕崩無嗣，俄羅斯陷入饑荒、農民起義、波蘭立陶宛入侵、多名「假德米特里」冒名稱帝。1610 年波軍佔莫斯科。1613 年羅曼諾夫家族崛起終止亂局。
From 1598-1613, after Rurikid Tsar Feodor died childless, Russia plunged into famine, peasant rebellions, Polish-Lithuanian invasion, and multiple 'False Dmitris' claiming the throne. Polish forces occupied Moscow in 1610. The 1613 Romanov accession ended the chaos.
2 月 21 日縉紳會議(Zemsky Sobor)選 16 歲米哈伊爾·羅曼諾夫為沙皇，結束動盪時代。羅曼諾夫王朝統治俄羅斯 304 年至 1917 年尼古拉二世退位、1918 年全家被布爾什維克處決。
On February 21, the Zemsky Sobor (assembly) elected 16-year-old Mikhail Romanov as Tsar, ending the Time of Troubles. The Romanov dynasty ruled Russia for 304 years until Nicholas II's 1917 abdication and the family's 1918 execution by the Bolsheviks.
牧首尼孔(Nikon)推行禮儀改革(改畫十字方式、修訂禮拜書)向希臘東正教看齊。引發大分裂(Raskol)，反對者「舊禮儀派」遭迫害數百年，數萬人寧自焚不從新禮，俄羅斯宗教史最深創傷。
Patriarch Nikon's liturgical reforms (changing the sign of the cross, revising service books) aligned Russian with Greek Orthodoxy. The 'Raskol' schism followed; 'Old Believers' were persecuted for centuries — tens of thousands burned themselves rather than accept new rites. Russia's deepest religious trauma.
5 月 10 歲彼得即位(初與兄伊凡共治、姊索菲亞攝政)。1697-98 年微服遊歐學造船與工業，回國後強迫剪鬍、引西式行政、軍事、教育、曆法。43 年統治把俄羅斯從中世紀邊緣推為歐洲強國。
In May, 10-year-old Peter ascended (initially co-ruling with brother Ivan, sister Sophia regent). His 1697-98 incognito European Grand Embassy taught him shipbuilding and industry. Returning, he forced beard-shaving, imported Western administration, military, education, calendar. His 43-year reign pushed Russia from medieval periphery to European great power.
5 月 27 日彼得大帝在涅瓦河口大北方戰爭新奪芬蘭灣濕地建城，命名「聖彼得堡」(向使徒彼得致敬)。徵調 4 萬農奴 9 年填沼建城，數萬人喪命。1712 年遷都，是俄羅斯「西望窗」的物質象徵。
On May 27, Peter the Great founded a city on Neva delta marshes recently captured from Sweden in the Great Northern War, naming it 'St. Petersburg' for the Apostle Peter. 40,000 serfs filled the swamps over 9 years; thousands died. Capital from 1712 — the physical embodiment of Russia's 'window to the West.'
10 月 22 日大北方戰爭擊敗瑞典後，元老院尊彼得為「皇帝」(Imperator)、「祖國之父」、「彼得大帝」。俄羅斯從沙皇國升格為帝國，正式躋身歐洲強國行列，俄羅斯帝國延續至 1917 年。
On October 22, after defeating Sweden in the Great Northern War, the Senate proclaimed Peter 'Imperator' (Emperor), 'Father of the Fatherland,' and 'the Great.' Russia rose from Tsardom to Empire, formally joining the European great powers. The Russian Empire endured until 1917.
5 月 7 日 Mikhail Lomonosov 創辦莫斯科大學，俄羅斯首所現代大學。Lomonosov 本人是博學家：化學、物理、天文、語言、詩歌全才，發現質量守恆律(早 Lavoisier 17 年)、預言金星大氣存在。
On May 7, Mikhail Lomonosov founded Moscow University, Russia's first modern university. Lomonosov was a polymath — chemistry, physics, astronomy, linguistics, poetry. He formulated the law of conservation of mass (17 years before Lavoisier) and predicted the existence of Venus's atmosphere.
1762/1/5 俄皇 Elizabeth 死，Peter III 繼位，因崇拜 Frederick II 立即停戰退盟，救 Prussia 於覆亡邊緣。
On Jan 5, 1762, Empress Elizabeth died; new tsar Peter III, a Frederick II fanboy, immediately withdrew Russia from the war, saving Prussia.
7 月 9 日德裔凱薩琳發動政變廢丈夫彼得三世，自立為俄皇。在位 34 年(史上女皇最久)，與伏爾泰通信、贊助藝術、3 次瓜分波蘭、奪克里米亞、敗鄂圖曼、把俄羅斯版圖擴大 50 萬平方公里。
On July 9, German-born Catherine staged a coup deposing her husband Peter III, becoming Empress. Her 34-year reign (the longest by a Russian Empress) corresponded with Voltaire, patronized arts, partitioned Poland three times, took Crimea, defeated the Ottomans — adding 500,000 km² to the Empire.
9 月哥薩克 Yemelyan Pugachev 自稱「真彼得三世」起義反凱薩琳，召集農奴、烏拉爾工人、巴什基爾、塔塔爾族橫掃伏爾加流域 16 個月，威脅莫斯科。1775 年被斬首示眾。俄羅斯史上規模最大農民起義。
In September, Cossack Yemelyan Pugachev claimed to be the 'true Peter III' and rebelled against Catherine, rallying serfs, Ural workers, Bashkirs, and Tatars to sweep the Volga region for 16 months — threatening Moscow. Beheaded publicly in 1775. The largest peasant rebellion in Russian history.
6 月拿破崙率 60 萬大軍跨涅曼河入俄。9 月攻博羅季諾、佔莫斯科(俄人焚城)。冬天撤退時被嚴寒、飢餓、哥薩克襲擊摧毀，60 萬軍只 4 萬人活著回。「1812 序曲」、《戰爭與和平》皆描寫此役。
In June, Napoleon led 600,000 troops across the Niemen into Russia. In September he won Borodino and took Moscow (Russians burned the city). Winter retreat saw cold, starvation, and Cossack attacks destroy his army — only 40,000 of 600,000 returned. Inspired Tchaikovsky's 1812 Overture and Tolstoy's War and Peace.
12 月 14 日亞歷山大一世駕崩、繼承不明之際，3 千俄軍貴族青年軍官在聖彼得堡參議院廣場武裝示威，要求君主立憲。被尼古拉一世以炮火鎮壓，5 名領袖絞死、百人流放西伯利亞。是俄羅斯首次貴族對沙皇專制的政治反抗。
On December 14, amid succession confusion after Alexander I's death, 3,000 noble young officers staged armed protest in Senate Square, St. Petersburg, demanding constitutional monarchy. Nicholas I suppressed them with cannon — 5 leaders hanged, 100+ exiled to Siberia. Russia's first noble revolt against tsarist autocracy.
Kazan 大學數學家 Nikolai Lobachevsky 發表雙曲幾何，否定歐幾里得平行公設。挑戰 2000 年幾何學基礎，雖當時被忽視，半世紀後成為 Riemann 幾何與愛因斯坦相對論的數學基礎。
Kazan University mathematician Nikolai Lobachevsky published hyperbolic geometry, rejecting Euclid's parallel postulate. Challenging 2,000 years of geometric foundations, his work was ignored at the time but half a century later became the mathematical basis for Riemannian geometry and Einstein's relativity.
3 月 3 日「解放者沙皇」亞歷山大二世發布解放令，2300 萬農奴(全國 1/3 人口)獲人身自由。是俄羅斯近代化關鍵改革，但農民仍要付高額土地贖金，社會矛盾未消，為日後革命埋下伏筆。
On March 3, 'Tsar Liberator' Alexander II issued the Emancipation Manifesto. 23 million serfs (a third of the population) gained personal freedom. A pivotal modernization reform — but peasants still owed massive land redemption payments, and unresolved tensions seeded the coming revolutions.
俄國化學家門得列夫發表元素週期表，預測未知元素的存在，是化學史上最重要的分類系統。
Russian chemist Mendeleev publishes the periodic table, predicting the existence of undiscovered elements — the most important classification system in chemistry.
3 月 6 日 Dmitri Mendeleev 在俄羅斯化學學會發表元素週期表。創新處：依原子量排序但留空位給未發現元素並預測其性質。1875 鎵、1879 鈧、1886 鍺被發現完美吻合預測，週期表成現代化學基石。
On March 6, Dmitri Mendeleev presented his Periodic Table to the Russian Chemical Society. The innovation: arranging by atomic weight, leaving gaps for undiscovered elements and predicting their properties. The discoveries of gallium (1875), scandium (1879), and germanium (1886) confirmed his predictions — the foundation of modern chemistry.
聾啞數學教師 Konstantin Tsiolkovsky 發表《探索宇宙空間的反作用力裝置》，建立火箭運動方程式 Δv = ve · ln(m0/m1)。預言液體燃料火箭、太空站、太空電梯。是太空飛行理論奠基人，後世蘇聯太空計畫的精神導師。
Deaf-mute math teacher Konstantin Tsiolkovsky published 'Exploration of Outer Space by Means of Reaction Devices,' establishing the rocket equation Δv = ve · ln(m0/m1). He predicted liquid-fuel rockets, space stations, and space elevators — the founder of astronautics theory and spiritual mentor of the Soviet space program.
2 月 8 日日軍偷襲旅順港俄艦隊。19 個月戰爭，1905 年對馬海戰俄波羅的海艦隊全滅、奉天會戰俄軍敗。9 月《樸茨茅斯條約》俄割讓南滿、朝鮮歸日。是首次亞洲擊敗歐洲強國，撼動全球種族秩序觀。
On February 8, Japan launched surprise attack on Russian fleet at Port Arthur. After 19 months of war — including the 1905 Tsushima naval annihilation of Russia's Baltic Fleet and Mukden land defeat — the September Portsmouth Treaty ceded southern Manchuria; Korea went to Japan. The first time an Asian nation defeated a European great power, shaking global racial assumptions.
12 月 Ivan Pavlov 獲諾貝爾生理學或醫學獎，表彰其消化系統研究。但更知名的是他 1890s 開始的「條件反射」實驗：搖鈴餵狗，狗聽鈴即流口水。是行為心理學奠基實驗，影響深遠。
In December, Ivan Pavlov won the Nobel Prize in Physiology/Medicine for digestive system research. More famous, however, were his 1890s 'conditioned reflex' experiments: ringing a bell while feeding dogs led them to salivate at the bell alone — the founding experiment of behavioral psychology.
1 月 22 日(舊曆 9 日)聖彼得堡冬宮廣場神父加邦率工人請願示威，被沙皇衛隊開槍射殺逾百人，史稱「血腥星期日」。引爆全國罷工、暴動、戰艦兵變。10 月十月詔書承諾立憲，首屆杜馬選出。1917 革命的預演。
On January 22 (Jan 9 OS), Father Gapon led workers to petition at Winter Palace Square, St. Petersburg — Tsarist guards fired, killing over 100. 'Bloody Sunday' triggered nationwide strikes, riots, and battleship mutinies. The October Manifesto promised a constitution; the first Duma was elected. A dress rehearsal for 1917.

World War I erupts, killing over 17 million people, dissolving four empires and reshaping the global political order.
1891 年動工、1916 年莫斯科到符拉迪沃斯托克全線通車，全長 9289 公里，世界最長鐵路至今。打通遠東與歐洲、加速西伯利亞殖民與資源開發、強化俄羅斯遠東軍事投射能力。
Started in 1891 and completed in 1916, the Trans-Siberian connected Moscow to Vladivostok over 9,289 km — still the world's longest railway. It opened the Far East to Europe, accelerated Siberian colonization and resource extraction, and projected Russian military power east.
3 月俄國首都彼得格勒工人暴動加軍隊譁變，沙皇尼古拉二世退位，羅曼諾夫王朝終結，臨時政府成立。

On October 4, the R-7 rocket from Baikonur launched Sputnik 1 (a 58-cm aluminum ball) into orbit. It circled Earth every 96 minutes, transmitting beeps for 21 days. The 'Sputnik crisis' shocked America, triggering NASA's founding (1958), education reform, and the Space Race.
10 月 4-7 日(Sputnik 兩週年)Luna 3 飛掠月球背面，首次拍攝人類從未見過的另一半月球。29 張照片質量粗糙但歷史性。從此月背地名以蘇聯科學家為主：Lomonosov、Mendeleev、Tsiolkovsky 隕石坑。
On October 4-7 (the second anniversary of Sputnik), Luna 3 flew past the Moon and took the first-ever photographs of the lunar far side — the half humanity had never seen. 29 grainy but historic images. Lunar far-side features now bear Soviet scientists' names: Lomonosov, Mendeleev, Tsiolkovsky craters.
4 月 12 日 27 歲蘇聯空軍上尉 Yuri Gagarin 搭 Vostok 1 飛船升空，108 分鐘繞地球一圈。「Поехали!」(我們走吧)成名言。是人類首次太空飛行，蘇聯太空競賽再勝一場，Gagarin 成全球巨星。
On April 12, 27-year-old Soviet Air Force lieutenant Yuri Gagarin launched aboard Vostok 1, orbiting Earth in 108 minutes. His 'Поехали!' (Let's go!) became iconic. The first human spaceflight — another Soviet Space Race victory; Gagarin became a global icon.
7 月 4 日蘇聯首艘戰略核潛艇 K-19 在北大西洋演習，反應爐冷卻系統故障。8 名艇員自願進入輻射區搶修，全數於數週內死亡。輻射污染艇身永久。電影《K-19: The Widowmaker》(2002)原型。
On July 4, the USSR's first strategic nuclear submarine K-19 suffered reactor coolant failure during North Atlantic exercises. 8 crew members volunteered to enter the radiation zone for repairs — all died within weeks. Radiation contaminated the boat permanently. Inspired the 2002 film 'K-19: The Widowmaker.'
10 月 30 日蘇聯在新地島試爆 Tsar Bomba(AN602)熱核裝置，當量 50 百萬噸 TNT(約 1500 倍廣島)。蘑菇雲高 64 公里、衝擊波繞地球三圈、1000 公里外可見閃光。是史上最大規模單一爆炸事件。
On October 30, the USSR tested Tsar Bomba (AN602) thermonuclear device at Novaya Zemlya — yield 50 megatons TNT (~1,500x Hiroshima). The mushroom cloud reached 64 km; the shockwave circled Earth three times; the flash was visible 1,000 km away. The largest single explosion in history.
10 月 16-28 日 13 天蘇聯在古巴部署 R-12 飛彈被美 U-2 偵察發現。美海上封鎖、全球進入 DEFCON 2。Khrushchev 與甘迺迪秘密交易：蘇撤古巴飛彈、美撤土耳其飛彈。人類史上最接近全面核戰的 13 天。
From October 16-28 (13 days), the US discovered Soviet R-12 missiles in Cuba via U-2. America blockaded; the world reached DEFCON 2. Khrushchev and Kennedy secretly traded: Soviets withdrew from Cuba; US withdrew missiles from Turkey. Humanity's closest brush with full nuclear war.
3 月 18 日 Alexei Leonov 從 Voskhod 2 出艙，是人類首次太空漫步(EVA)，12 分 9 秒。但艙外服膨脹差點回不去，緊急洩壓才擠回艙。冷戰太空競賽蘇聯再奪一勝。
On March 18, Alexei Leonov stepped out of Voskhod 2 — humanity's first spacewalk (EVA), lasting 12 minutes 9 seconds. His suit ballooned dangerously; only an emergency pressure release allowed him to squeeze back in. Another Soviet Space Race triumph.
4 月 23 日 Soyuz 1 首飛(雖墜毀殉職首位太空人)，但開啟 60 年延續至今的 Soyuz 計畫。150+ 次飛行、史上最可靠載人太空船。1975 阿波羅-Soyuz 對接、Mir + ISS 主要交通工具。Sputnik 之後蘇/俄太空計畫主軸。
On April 23, Soyuz 1 first flew (though it crashed killing its cosmonaut), launching the 60-year Soyuz program continuing today. 150+ flights, the most reliable crewed spacecraft in history. Apollo-Soyuz docking 1975, primary transport for Mir and ISS. The backbone of Soviet/Russian human spaceflight.
8 月 20-21 日華約 5 國軍隊 50 萬進入捷克，鎮壓 Dubček「人性面孔的社會主義」改革。「布拉格之春」結束。Brezhnev 主義(社會主義國家有限主權論)正式提出。共產陣營改革派受重大挫敗。
On August 20-21, 500,000 Warsaw Pact troops from 5 countries invaded Czechoslovakia, crushing Dubček's 'socialism with a human face' reforms. The 'Prague Spring' ended. The Brezhnev Doctrine (limited sovereignty for socialist states) was articulated. A major setback for communist reformers.
12 月 31 日蘇聯 Tupolev Tu-144 首飛，比英法 Concorde 早 2 個月，是史上首架超音速客機。可載 140 人、Mach 2.15(2200 km/h)。但 1973 巴黎航展墜毀、1978 墜機後限縮服役，1999 年 NASA 也用 Tu-144 做研究。
On December 31, the Soviet Tupolev Tu-144 first flew — two months before Britain-France's Concorde. The world's first supersonic airliner: 140 passengers, Mach 2.15 (2,200 km/h). But after a 1973 Paris Air Show crash and a 1978 fatal accident, service was curtailed. NASA used a Tu-144 for research as late as 1999.
12 月 15 日 Venera 7 在金星表面成功軟著陸，是人類首次在另一顆行星(地球以外)實現軟著陸並回傳資料(23 分鐘)。確認金星表面溫度 475°C、氣壓 90 atm。蘇聯金星探測領先美國甚多。
On December 15, Venera 7 made the first-ever soft landing on another planet, transmitting data from Venus's surface for 23 minutes. It confirmed surface temperature of 475°C and pressure of 90 atmospheres. The USSR led the US substantially in Venus exploration.
4 月 19 日 Salyut 1 升空，是史上第一座太空站。可容 3 人 23 天。Soyuz 11 太空人完成首次太空站任務但返航時氣閥失效，3 人窒息死亡。Salyut 計畫共 7 個太空站延續至 1986 Mir。
On April 19, Salyut 1 launched — the first space station in history. It could host 3 people for 23 days. Soyuz 11 cosmonauts completed the first space station mission but died of asphyxiation when a valve failed during return. The Salyut program eventually built 7 stations through 1986, leading to Mir.
12 月 24 日蘇軍入侵阿富汗扶植傀儡政權。10 年戰爭(1979-1989)耗資巨大、1.5 萬蘇軍陣亡，CIA 與沙特暗助 mujahideen 游擊隊(其中即 Bin Laden)。被視為蘇聯版越戰，加速蘇聯經濟崩潰。
On December 24, Soviet forces invaded Afghanistan to install a puppet regime. The 10-year war (1979-1989) drained resources, killed 15,000 Soviet troops; the CIA and Saudis covertly armed the mujahideen (including a young bin Laden). Seen as the Soviet Vietnam, it accelerated USSR's economic collapse.
12 月首艘 Typhoon 級(Project 941 Akula)服役。長 175 公尺、水面 48,000 噸，史上最大潛艇。雙體鈦合金結構、可在北極冰下發射 20 枚 R-39 SLBM(每枚 10 個核彈頭)。電影《獵殺紅色十月》原型。
In December, the first Typhoon-class (Project 941 Akula) entered service. 175 m long, 48,000 tons surfaced — the largest submarine in history. Double-hulled titanium construction, capable of launching 20 R-39 SLBMs (each with 10 warheads) from under Arctic ice. Inspiration for 'The Hunt for Red October.'
6 月蘇聯科學院 Alexey Pajitnov 在工作之餘設計 Tetris 益智遊戲(俄文 тетрамино + теннис)。蘇聯版權歸國家，1989 任天堂與美國 Bullet-Proof Software 取得版權，與 Game Boy 綁售大爆。全球累計售逾 5 億套，史上最暢銷電玩。
In June, Alexey Pajitnov of the Soviet Academy of Sciences designed Tetris in his spare time (the name combines 'tetra' and 'tennis'). The Soviet copyright belonged to the state; in 1989 Nintendo and US Bullet-Proof Software acquired rights and bundled it with Game Boy — a smash hit. Over 500 million copies sold worldwide — the best-selling video game in history.
3 月 11 日 54 歲 Gorbachev 出任蘇共總書記。提出「改革」(perestroika)、「公開化」(glasnost)、「新思維」對外政策。意圖救蘇聯卻意外加速崩潰。1990 年諾貝爾和平獎，1991 年解體後辭職。
On March 11, 54-year-old Gorbachev became Soviet General Secretary. He launched 'perestroika' (restructuring), 'glasnost' (openness), and 'new thinking' foreign policy. Intended to save the USSR, his reforms accelerated its collapse. 1990 Nobel Peace Prize; resigned at the 1991 dissolution.
2 月 19 日 Mir 太空站核心艙升空，是史上首座永久有人居住的太空站。在軌 15 年(1986-2001)，太空人 Polyakov 創單次連續 437 天紀錄至今。1995 年起與美國太空梭對接，是冷戰後合作典範。
On February 19, the core module of Mir launched — the first continuously inhabited space station in history. In orbit for 15 years (1986-2001), cosmonaut Polyakov set the still-unbroken record of 437 continuous days. From 1995, US Space Shuttles docked with Mir — a model of post-Cold War cooperation.
4 月 26 日烏克蘭 Chernobyl 核電廠 4 號反應爐爆炸，輻射雲擴散全歐。31 人立即死亡，數萬人後續罹癌死亡。蘇聯初期掩蓋資訊重創公信力，加速 Glasnost 與蘇聯解體。
On April 26, Reactor 4 at Chernobyl Nuclear Plant in Ukraine exploded. Radiation clouds spread across Europe. 31 died immediately; tens of thousands later from cancer. The Soviet cover-up early on shattered government credibility, accelerating Glasnost and the USSR's collapse.
1987/12/8 Reagan 與 Gorbachev 簽中程導彈條約，首次消除整類核武（500-5500 km）。
On Dec 8, 1987, Reagan and Gorbachev signed the Intermediate-Range Nuclear Forces Treaty—the first to eliminate an entire class of nuclear weapons (500-5500 km).
11 月 15 日蘇聯 Buran(暴風雪)太空梭由 Energia 火箭發射，無人軌道飛行 206 分鐘後自動降落 Baikonur 跑道，分毫不差。比美國梭更先進(無人自動)。但 1991 年蘇聯解體後計畫取消，唯一一次飛行。2002 機庫倒塌摧毀。
On November 15, the Soviet Buran (Snowstorm) shuttle launched on the Energia rocket. After 206 minutes of unmanned orbital flight, it autolanded at Baikonur with perfect precision — more advanced than the US Shuttle (fully automated). But the program was canceled after the 1991 collapse — Buran's only flight. The hangar collapsed in 2002, destroying it.
12 月 21 日蘇聯安托諾夫設計局 An-225「Mriya(夢想)」首飛。翼展 88 公尺、最大起飛重 640 噸、6 引擎、原為運輸 Buran 太空梭。是史上最大飛機，2022 年俄烏戰爭中被毀於 Hostomel 機場。
On December 21, the Soviet Antonov Design Bureau's An-225 'Mriya' (Dream) first flew. Wingspan 88 m, max takeoff weight 640 tons, 6 engines — designed to transport the Buran shuttle. The largest aircraft ever built. Destroyed at Hostomel Airport during the 2022 Russian invasion of Ukraine.
東德開放邊境，柏林圍牆被推倒，冷戰時代象徵性終結，德國統一與蘇聯解體相繼而來。
East Germany opens its borders; the Berlin Wall falls — the symbolic end of the Cold War, followed by German reunification and the Soviet collapse.
1989/11/9 東德官員誤報旅行新規即時生效，民眾湧向圍牆，衛兵不阻，世紀性時刻象徵冷戰結束。
On Nov 9, 1989, an East German spokesperson mistakenly announced immediate travel liberalization; crowds rushed the Wall unopposed—the century's defining moment.
12 月 25 日戈巴契夫辭蘇聯總統職，紅旗從克里姆林宮降下，蘇聯正式解體。15 個加盟共和國獨立，葉爾欽掌俄羅斯聯邦。冷戰結束、東歐共產集團瓦解，美國成唯一超級大國。
On December 25, Gorbachev resigned as Soviet President; the red flag came down from the Kremlin, dissolving the USSR. 15 republics gained independence; Yeltsin led the Russian Federation. The Cold War ended, the Eastern Bloc collapsed, and America became the sole superpower.
3 月 26 日 KGB 出身的普京當選俄羅斯總統(葉爾欽 1999 年底辭職指定他接班)。終結 1990s 動盪、重整國家權威、能源出口復興經濟，但壓制媒體、打擊寡頭、強化威權，俄羅斯「主權民主」轉向開始。
On March 26, KGB-trained Putin won the Russian presidency (Yeltsin had resigned and named him heir at end of 1999). He ended 1990s chaos, restored state authority, and revived the economy through energy exports — but suppressed media, attacked oligarchs, and strengthened authoritarianism, beginning Russia's turn to 'sovereign democracy.'
2 月 24 日普京發動「特別軍事行動」全面入侵烏克蘭。是 2014 克里米亞、頓巴斯衝突的延續。歐洲二戰後最大規模戰爭，全球能源糧食危機。西方對俄前所未有制裁，俄羅斯被多國與國際機構排除。
On February 24, Putin launched the 'special military operation' — full-scale invasion of Ukraine. A continuation of the 2014 Crimea/Donbas conflicts. Europe's largest war since WW2, sparking global energy and food crises. The West imposed unprecedented sanctions; Russia was expelled from many international institutions.
