Step-by-step explanation:
Charles I was beheaded because he invited the Dutch to invade England and committed adultery.
During the English Civil War, Charles I, who was the King of England at the time, was captured by the parliamentary 'roundheads' and put on trial. The main charges against him were that he had invited foreign forces, including the Dutch, to invade England and that he had committed adultery. These actions were considered treasonous and led to his execution by beheading in 1649.
