 By 1541, King Henry VIII of England had broken with the Church of Rome and declared himself Supreme Head of the Church of England. The pope's grant of Ireland to the English monarch became invalid, so Henry summoned a meeting of the Irish Parliament to change his title from Lord of Ireland to King of Ireland. However much of the island was beyond English control, resulting in the extended Tudor conquest of Ireland that only made the Kingdom of Ireland a reality in 1603, at the conclusion of the Nine Years' War (Ireland). Nevertheless, Ireland retained its own parliament, becoming an independent state in 1642-1649 (Confederate Ireland), and again in 1688-91. Only warfare such as the Williamite War in Ireland and subsequent occupation enabled the English crown from 1692, and successive British states from 1707, to retain the country.
