March 21 in History

The Battle of Alexandria was fought on 21 March 1801, where the British army and naval forces repelled an assault by the French army as part of the French invasion of Egypt and Syria. Led by General Sir Ralph Abercromby, the British entrenched army engaged a French force under Divisional-general Jacques-François Menou near the ruins of Nicopolis, on the narrow spit of land between the Mediterranean Sea and Abukir. The British routed Menou's army after several hours of fierce fighting, though Abercromby was mortally wounded. Part of the French casualties at Alexandria was caused by British naval force under Sidney Smith, whose role was also important in suppressing the French attacks. John Hely-Hutchinson, who replaced Abercromby, led the British army to Alexandria and laid siege to the city, which surrendered in September.

The Napoleonic Wars (1803–1815) were a global series of conflicts fought by a fluctuating array of European coalitions against the French First Republic (1803–1804) under the First Consul followed by the First French Empire (1804–1815) under the Emperor of the French, Napoleon I. The wars originated in political forces arising from the French Revolution (1789–1799) and from the French Revolutionary Wars (1792–1802) and produced a period of French domination over Continental Europe. The wars are categorised as seven conflicts, five named after the coalitions that fought Napoleon, plus two named for their respective theatres: the War of the Third Coalition, War of the Fourth Coalition, War of the Fifth Coalition, War of the Sixth Coalition, War of the Seventh Coalition, the Peninsular War, and the French invasion of Russia.

The Hungarian Soviet Republic, also known as the Socialist Federative Soviet Republic of Hungary was a short-lived state that existed from 21 March 1919 to 1 August 1919, succeeding the First Hungarian Republic. The Hungarian Soviet Republic was a small rump state run by communists and socialists which, at its time of establishment, controlled approximately only 23% of Hungary's historic territory. The nominal head of government was Sándor Garbai, but the de facto leader was Béla Kun, leader of the Party of Communists in Hungary. Unable to reach an agreement with the Triple Entente, which maintained an economic blockade of Hungary, in dispute with neighboring countries over territorial disputes, and beset by profound internal social changes, the Hungarian Soviet Republic failed in its objectives and was abolished a few months after its existence. Its main figure was the Communist Béla Kun, despite the fact that in the first days the majority of the new government consisted of radical Social Democrats. The new system effectively concentrated power in the governing councils, which exercised it in the name of the working class.

It began in the aftermath of the Second World War and ended with the dissolution of the Soviet Union in 1991.

In addition to the struggle for ideological and economic influence and an arms race in both conventional and nuclear weapons, the Cold War was expressed through technological rivalries such as the Space Race, espionage, propaganda campaigns, embargoes, and sports diplomacy.

Paraplegia, or paraparesis, is an impairment in motor or sensory function of the lower extremities. The word comes from Ionic Greek (παραπληγίη) "half-stricken". It is usually caused by spinal cord injury or a congenital condition that affects the neural (brain) elements of the spinal canal. The area of the spinal canal that is affected in paraplegia is either the thoracic, lumbar, or sacral regions. If four limbs are affected by paralysis, tetraplegia or quadriplegia is the correct term. If only one limb is affected, the correct term is monoplegia. Spastic paraplegia is a form of paraplegia defined by spasticity of the affected muscles, rather than flaccid paralysis.

The United Nations Framework Convention on Climate Change (UNFCCC) is the UN process for negotiating an agreement to limit dangerous climate change. It is an international treaty among countries to combat "dangerous human interference with the climate system". The main way to do this is limiting the increase in greenhouse gases in the atmosphere. The Convention established the principle of "common but differentiated responsibilities," which asserts that all countries share responsibility for addressing climate change. However, developed countries are expected to assume a leading role because of their greater historical greenhouse gas emissions. It was signed in 1992 by 154 states at the United Nations Conference on Environment and Development (UNCED), informally known as the Earth Summit, held in Rio de Janeiro. The treaty entered into force on 21 March 1994. "UNFCCC" is also the name of the Secretariat charged with supporting the operation of the convention, with offices on the UN Campus in Bonn, Germany.
