King Henry VIII came first, reigning from 1509 to 1547, while King James I ascended to the throne later, in 1603. Henry VIII is well-known for his six marriages and his role in the English Reformation, which led to the Church of England breaking away from the authority of the Pope and the Roman Catholic Church.
On the other hand, King James I is famous for commissioning the King James Version of the Bible and for overseeing the unification of the crowns of England and Scotland. Understanding the timeline of these two monarchs helps clarify the significant historical events and changes that occurred in England during the Tudor and early Stuart periods.
