After the Glorious Revolution in 1688, the birthdays of the monarchs of Great Britain began to be celebrated throughout that country and her Colonies.
The King's loyal subjects celebrated his birthday by lighting bonfires, shooting off fireworks and holding parades through the larger towns.
During the Colonial Period, there were six monarchs who ruled over Great Britain and her Colonies. The dates of their births, of course, varied; and so the holiday celebrated as The King's Birthday changed with each monarch's reign.
The following are the monarchs during the Colonial Period along with their birthdates:
William of Orange 27 May 1626
William III 04 November 1650
Anne 06 February 1665
George I 28 May 1660
George II 30 October 1683
George III 04 June 1738
