Charles I was married.
Charles I of England . 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 instead . His religious policies , coupled with his marriage to a Roman Catholic , generated the antipathy and mistrust of reformed groups such as the English Puritans and Scottish Covenanters , who thought his views too Catholic .
