Monarchy of Ireland
The Kingdom of Ireland started in 1542. Before 1603, Ireland shared a monarch with the Kingdom of England (but not with the Kingdom of Scotland) in a personal union. When Henry VIII's daughter Elizabeth I died in 1603, James VI and I became the first to be King of Ireland, King of England, and King of Scotland in a three-kingdom personal union. Between 1603 and 1707, the Kingdom of Ireland shared the monarchs of the Kingdom of Scotland and the Kingdom of England. Anne was the Queen of Ireland when the United Kingdom of Great Britain came into existence in 1707. Anne was Queen of Ireland and Queen of Great Britain. Between 1707 and 1801, the Kingdom of Ireland shared the British monarchy with the United Kingdom of Great Britain. (During the government of Oliver Cromwell, the British Isles became a republic: the Commonwealth of England, Scotland, and Ireland.) George III was King of Ireland when the United Kingdom of Great Britain and Ireland came into existence at the start of 1801. George III was the first to be king of the new kingdom, which combined the whole British Isles (except the Isle of Man) into one kingdom for the first time.
