The Action of 21 April 1806 was a minor engagement between a French frigate and British forces off South Africa during the Napoleonic Wars. The Île Bonaparte and Île de France constituted French outposts in the Indian Ocean, from which privateers and frigate squadrons could engage in commerce raiding and disrupt British shipping.

In the ensuing battle, Captain Bourayne displayed superior sailmanship and managed to fend off his much strong opponent by a combination of manoeuvers that rendered the batteries of Tremendous ineffective, and threatened her of sustaining raking fire.

The Louisiana gubernatorial election of 1896 was held on April 21, 1896. Like most Southern states between Reconstruction and the civil rights era, Louisiana's Republican Party was virtually nonexistent in terms of electoral support. As Louisiana had not yet adopted party primaries, this meant that the Democratic Party convention nomination vote was supposed to be the real contest over who would be governor. However, the Republicans and Populists put forward a joint candidate, John N. Pharr. With combined Republican and Populist support Pharr garnered 43% of the vote, although the Democratic nominee, Murphy J. Foster was elected with 57% of the vote.

General elections to the Cortes Generales were held in Spain on 21 April 1907. At stake were all 404 seats in the Congress of Deputies. Though formally competitive, the 1907 general election was held under the customary system of Turno Pacifico; in accordance with a long-standing power-sharing arrangement, elections (under influence by machine bosses called caciques) served as a rubber stamp for a routine handover of power initiated by the King. The 1907 election, as expected, sanctioned the pre-arranged handover from the Liberals to the Conservatives.

2002 — French presidential election, 2002
The 2002 French presidential election consisted of a first round election on 21 April 2002, and a runoff election between the top two candidates (Jacques Chirac and Jean-Marie Le Pen) on 5 May 2002. This presidential contest attracted a greater than usual amount of international attention because of far-right candidate Le Pen's unexpected appearance in the runoff election. Chirac ran for a second term, emphasising a strong economy (mostly unaffected by downturns in Germany and the USA). It was widely expected that Chirac and Lionel Jospin, the then prime minister and candidate for the Socialist Party, would be the most popular candidates in the first round, and would thus go on to face each other in the runoff.

Following the Houla massacre of 25 May 2012, in which 108 people were summarily executed, and the subsequent Free Syrian Army (FSA) ultimatum to the Syrian Ba'athist government, the ceasefire practically collapsed as the FSA began nationwide offensives against government troops.
