There are some dates in history that are repeated time and again, producing an odd synergy. For example, the 23rd November is the date on which John F. Kennedy was assasinated in 1963; it was the date British prime minister Margaret Thatcher ended her premiership in 1990; and it was the date on which Angela Merkel became the first ever female Chancellor of Germany in 2005.
Today's date, 21st April, is another such date. It has seen a host of interesting historical events, births and deaths. Here we look at five of the most significant things to happen on this day.Reuse content
