enabled the Conservatives to re-take control of Parliament in 1979, under
Margaret Thatcher, Britain's first female Prime Minister.
Although Thatcher's economic reforms
made her initially unpopular,
her decision in 1982 to retake the Falkland Islands from invading Argentine
forces, in what would become known as the Falklands War, changed her
fortunes and enabled a landslide victory in 1983.
After winning an
unprecedented third election in 1987, however, Thatcher's popularity began to
fade and she was replaced by former chancellor John Major in 1990.
Tensions between Protestants and Catholics in Northern Ireland came
to a head in the late 1960s, when nationalist participants in a civil rights
march were shot by members of the B Specials, a reserve
police force manned
almost exclusively by unionists. From this point the Provisional Irish
Republican Army, also known as the Provos or simply the IRA, began a
bombing campaign throughout the U.K., beginning
a period known as The
Troubles, which lasted until the late 1990s.
Prince Charles, the Prince of Wales and Elizabeth's eldest son married
Lady Diana Spencer in 1981; the couple had two children, William and Harry,
but divorced in 1992, during which year Prince Andrew and Princess Anne
also separated from their spouses, leading the
Queen to call the year her
'annus horribilis'. In 1997, Diana was killed in a car crash in Paris, leading to
a mass outpouring of grief across the United Kingdom, and indeed the world.
On the international stage, the second half of the 20th century was
dominated by the Cold War between the Soviet Union and its socialist allies
and the United States and its capitalist allies; the U.K. was a key supporter of
the latter, joining the anti-Soviet military alliance NATO in 1949. During this
period, the U.K. became involved in several Cold War conflicts, such as the
Korean War (1950–1953). In contrast, the Republic
of Ireland remained
neutral and provided troops to U.N. peace-keeping missions.
