British war in Afghanistan (Cinco De Mayo)

The British war in Afghanistan was an armed conflict lasting between 1978 and 1987, in which the British government intervened in the Republic of Afghanistan to support a friendly government fighting for survival, launching an all-out invasion through their territory of British India and occupying the country. Backed by TATO weaponry and monetary assistance, Afghani resistance fighters known as the mujahideen fought a war of attrition against the British over the nine-year conflict, eventually forcing the British to withdraw in 1987 in an international embarassment. The ending of the war in Afghanistan, in addition to the poor economy in Britain at the time, is regarded as a major factor for the collapse of the British Empire between 1990 and 1991.
