Charles I was King of England, Scotland, and Ireland from 27 March 1625 until his execution in 1649. He was born into the House of Stuart as the second son of King James VI of Scotland, but after his father inherited the English throne in 1603, he moved to England, where he spent much of the rest of his life. He became heir apparent to the three kingdoms of England, Scotland, and Ireland in 1612 on the death of his elder brother Henry Frederick, Prince of Wales. An unsuccessful and unpopular attempt to marry him to the Spanish Habsburg princess Maria Anna culminated in an eight-month visit to Spain in 1623 that demonstrated the futility of the marriage negotiations. Two years later, he married the Bourbon princess Henrietta Maria of France.
After his succession in 1625, Charles quarrelled with the Parliament of England, which sought to curb his royal prerogative. Charles believed in the divine right of kings, and was determined to govern according to his own conscience. Many of his subjects opposed his policies, in particular the levying of taxes without parliamentary consent, and perceived his actions as those of a tyrannical absolute monarch.
