On This Day

1187Saladin began the Siege of Jerusalem. The city surrendered in October 1187, which shocked Pope Urban III so much that he allegedly died as a result.
1586Anthony Babington, one of the leaders of the eponymous Babington Plot to execute Elizabeth I and replace her with the Catholic Mary Queen of Scots, was hanged drawn and quartered with six co-conspirators. Elizabeth was so horrified by the manner of execution that she ordered the remaining conspirators - destined to be executed on the following day - be hanged to death before the disemboweling began.
1643The Royalists suffered a defeat at the hands of the Parliamentarians, led by the Earl of Essex, at the first Battle of Newbury during the Civil Wars. Although both sides lost similarly small numbers, some historians consider it a turning point in Parliamentarian fortunes, leading to their alliance with the Scottish Covenanters and their eventual victory over Charles I.
