What was the cause of the Glorious Revolution?

The Glorious Revolution refers to the bloodless overthrow
in England of King James II and replacing him with William and Mary.  In 1685 King
Charles II died and his brother James became King James II.  James II was openly
Catholic and named many Roman Catholics to high posts in the government and the army. 
Most hoped that Mary, a child from his first marriage and who was a Protestant, would
become the new ruler once James II died.  But, in 1688, his second wife, who was Roman
Catholic, gave birth to a son.  Because the male heir took precedence in the line of
succession, it looked as if the Catholic son of James II would become the next king. 
Many in Parliament feared the long succession of Catholic kings.  Rule by a long
succession of Catholic Kings was also unacceptable to most English people.  After
withdrawing support from James II, the English Parliament offered the English throne to
Mary, the Protestant daughter of James II, and her Protestant husband, William of
Orange, the ruler of the Netherlands.  In 1688 William landed in England with a large
invasion force, and James II fled to France.  William and Mary were then named joint
rulers of England.  This change in monarchs, which came without a shot being fired,
became known as the Glorious Revolution.
