• Akkadian Empire (c. 2334–2154 BCE) — founded by Sargon of Akkad (Sargon I), widely considered history’s first empire-builder; united Sumerian city-states under a single ruler; capital at Akkad (location uncertain); empire collapsed amid drought and the Gutian invasions (dates are approximate; Mesopotamian chronology disputed).
• Babylonian Empire (Old Babylonian Period, c. 1894–1595 BCE) — Hammurabi (r. c. 1792–1750 BCE) expanded Babylon to dominate Mesopotamia and issued the Code of Hammurabi, one of the earliest comprehensive legal codes (282 laws inscribed on a stele, now in the Louvre).
• Neo-Babylonian (Chaldean) Empire (626–539 BCE) — Nebuchadnezzar II (r. 605–562 BCE) destroyed Jerusalem (586 BCE), deported Judeans in the Babylonian Captivity, and built the famed Hanging Gardens (ancient wonder, location debated); empire fell to Cyrus the Great of Persia (539 BCE).

• An Lushan Rebellion (755–763 CE) — massive revolt against the Tang dynasty launched by the northeastern frontier general An Lushan, who declared himself emperor of the rival Yan dynasty; the rebellion killed an estimated 13–36 million people (one of history’s deadliest conflicts); Tang authority never fully recovered, accelerating the decentralization that ended the dynasty in 907 CE.
• Imperial examination system (keju) — formalized Confucian meritocracy; inaugurated under the Sui dynasty (~605 CE) and greatly expanded under the Tang and Song; though limited in practice to elites who could afford study, the system selected officials via written exams on the Confucian classics and shaped Chinese bureaucracy for over 1,300 years; abolished only in 1905.

• Zheng He — Muslim admiral who commanded seven massive maritime expeditions (1405–1433) reaching Southeast Asia, India, Arabia, and East Africa; his treasure fleets used vessels (the so-called “treasure ships”) far larger than contemporary European ships; voyages ended when the Yongle Emperor’s successors banned ocean voyaging and destroyed the shipyards.
• Forbidden City (Zijin Cheng) — imperial palace complex in Beijing, construction begun 1406 under Yongle; 980 buildings on 180 acres, forbidden to ordinary citizens; served as the seat of imperial power through the Ming and Qing dynasties; now a UNESCO World Heritage Site.

• Taiping Rebellion (1850–1864) — one of history’s deadliest civil wars (~20–30 million dead); led by Hong Xiuquan, a failed exam candidate who claimed to be Jesus’s younger brother and sought to establish the “Heavenly Kingdom of Great Peace” (Taiping Tianguo); eventually suppressed by Qing forces aided by the “Ever-Victorious Army” under Frederick Townsend Ward and Charles Gordon.
• Boxer Rebellion (1899–1901) — uprising by the “Society of Righteous and Harmonious Fists” (Boxers) against foreign influence and Christian missionaries in China; the Qing court declared war on foreign powers; an eight-nation alliance (including Britain, Germany, Japan, and the US) relieved Beijing; the resulting Boxer Protocol (1901) imposed a crushing 450 million tael indemnity on China.

• Great Leap Forward (1958–1962) — Mao’s campaign to rapidly industrialize China through collectivized agriculture and backyard steel furnaces; resulted in the Great Chinese Famine, killing an estimated 15–55 million people; widely considered one of the deadliest man-made disasters in history.
• Cultural Revolution (1966–1976) — Mao’s campaign to purge “bourgeois” elements and reassert ideological purity; Red Guards attacked intellectuals, destroyed cultural artifacts, and persecuted millions; schools closed; the Gang of Four (including Mao’s wife Jiang Qing) were later arrested after Mao’s death; ended with his death in 1976.
• Deng Xiaoping’s reforms — after Mao’s death, Deng (paramount leader from ~1978) launched Reform and Opening Up (gaige kaifang); established Special Economic Zones; introduced market mechanisms into state socialism; China’s GDP grew at ~10% annually for decades; the Tiananmen Square massacre (June 4, 1989) crushed pro-democracy protests during this era.

India

Maurya and Gupta Empires

• Maratha Confederacy — Hindu confederacy that challenged Mughal and later British dominance; Shivaji Bhonsle (1630–1680) founded it, crowned himself Chhatrapati (paramount sovereign) in 1674, and developed guerrilla warfare in the Western Ghats; after Aurangzeb’s death (1707) the Marathas became the dominant power in India; their defeat by the Afghan Ahmad Shah Durrani at the Third Battle of Panipat (1761) checked their northward expansion; the confederacy dissolved under British pressure by 1818.
• British East India Company and Battle of Plassey — the English East India Company, chartered 1600, used trading posts to gradually build political power; Robert Clive defeated the Nawab of Bengal Siraj ud-Daulah at the Battle of Plassey (June 23, 1757) through treachery with Mir Jafar; this victory effectively made the Company the ruler of Bengal and began British territorial empire in India; the Company collected taxes, maintained armies, and governed millions until 1858.
• Indian Rebellion of 1857 (Sepoy Mutiny / First War of Independence) — began as a mutiny among Indian soldiers (sepoys) of the Bengal Army over the greased cartridges rumored to be coated with pig and cow fat (offensive to Muslims and Hindus); spread into a broad rebellion across northern and central India; Delhi, Lucknow, and Kanpur were major flashpoints; suppressed by late 1858; the British Crown dissolved the East India Company and assumed direct rule, inaugurating the British Raj.

• Treaty of Waitangi (February 6, 1840) — treaty signed between the British Crown and approximately 540 Maori chiefs in New Zealand; the English and Maori texts differ in key ways: the English version ceded sovereignty to the Crown, while the Maori version (te Tiriti) used the word kawanatanga (governance) and preserved tino rangatiratanga (chieftainship) over lands and treasures; the discrepancy has fueled two centuries of dispute over Maori land and rights; Waitangi Day (February 6) is New Zealand’s national day; the treaty is now regarded as a founding constitutional document of New Zealand.
• Eva Perón / Evita (1919–1952) — born María Eva Duarte; actress who became the wife of Argentine President Juan Perón (president 1946–1955, 1973–1974); beloved by the Argentine working class (“the shirtless ones,” los descamisados) for social welfare programs distributed through the Eva Perón Foundation; championed women’s suffrage, enacted in Argentina in 1947; her early death from cervical cancer at 33 transformed her into an enduring icon; the musical Evita (Rice and Lloyd Webber, 1978) dramatized her life.

• Young Turks / Committee of Union and Progress (CUP) — reformist revolutionary movement that deposed Sultan Abdulhamid II in the Revolution of 1908; dominated the late Ottoman government; the CUP leadership (the “Three Pashas”: Enver, Talaat, Cemal) led the empire into World War I on the German side; oversaw the Armenian Genocide (1915–1916), the deportation and mass killing of an estimated 600,000–1.5 million Armenians.
