1791 — Haitian Revolution
The Haitian Revolution, also known as the Haitian War of Independence, was a successful insurrection by enslaved Africans against French colonial rule in Saint-Domingue, now the sovereign state of Haiti. The revolution was one of the only known slave rebellions in human history that led to the founding of a state which was both free from slavery (though not from forced labour) and ruled by former captives. Vincent Ogé's 1790 revolt by free Mulattoes (of mixed French and African ancestry) pressured the French Revolutionary government to grant them citizenship in May 1791, leading to further clashes with slave owners that destabilized Saint-Domingue and led to the slave revolt on 21 August 1791, which ended with the former colony's independence on 1 January 1804, with the ex-slave Toussaint Louverture emerging as its most prominent general.

Striking northwestward for Memphis with 2,000 cavalry, Forrest lost about a quarter of his strength because of exhausted horses.

General elections to the Cortes Generales were held in Spain on 21 August 1881. At stake were all 392 seats in the Congress of Deputies. Though formally competitive, the 1881 general election was held under the recently developed system of Turno Pacifico; in accordance with a semi-formal power-sharing arrangement brokered by Antonio Cánovas del Castillo, elections (under influence by machine bosses called caciques) served as a rubber stamp for a routine handover of power initiated by the King. The 1881 election, as expected, sanctioned the pre-arranged handover from the Conservatives to the Liberals.

The Battle of Scimitar Hill (Turkish: Yusufçuk Tepe Muharebesi, lit.

It was also the largest single-day attack ever mounted by the Allies at Gallipoli, involving three divisions. The purpose of the attack was to remove the immediate Ottoman threat from the exposed Suvla landing and to link with the ANZAC sectors to the south. Launched on 21 August 1915 to coincide with the simultaneous attack on Hill 60, it was a costly failure, in which the Turks were forced to use all their reserves in "severe and bloody fighting" far into the night, with some Turkish trenches lost and retaken twice.

1920 — Battle of Przasnysz
The Battle of Przasnysz took place on August 21, 1920, near the towns of Przasnysz and Ciechanow, during the Polish-Soviet War. Polish forces of Lida Rifle Regiment and 202. Infantry Regiment clashed with elements of Red Army’s 16th and 23rd Infantry Divisions. After the victorious battle of the Wkra river, units of Polish 5th Army (General Wladyslaw Sikorski), began their assault towards Przasnysz and Mlawa (August 18).

As a result, on August 20 General Mikhail Tukhachevsky ordered his troops to concentrate in the area Ciechanow - Przasnysz - Makow Mazowiecki.

1991 — 1991 Soviet coup attempt
In August 1991, hardliners of the Communist Party of the Soviet Union (CPSU) attempted to forcibly seize control of the country from Mikhail Gorbachev, who was Soviet president and General Secretary of the CPSU at the time. The coup leaders consisted of top military and civilian officials, including Vice President Gennady Yanayev, who together formed the State Committee on the State of Emergency (Russian: ГКЧП, romanized: GKChP). Opposed to Gorbachev's reform program, they were angry at the loss of control over Eastern European states and fearful of the New Union Treaty, which was on the verge of being signed by the Soviet Union (USSR). The treaty was to decentralize much of the central Soviet government's power and distribute it among its fifteen republics. Boris Yeltsin's demand for more autonomy to the republics opened a window for the plotters to organize the coup. The attempt took place between 19 and 21 August 1991; as a result, the events were referred to as the August Coup.
