March 27, 1625 — Charles the First becomes King of Britain

Charles the First, destined to end his rein several inches shorter than he began it, was a firm believer in his divinely ordained autocratic rights as King of England, Scotland and Ireland.  (He also claimed to be King of France, although even a claim of King of Calais would have been inaccurate, the English having lost their last French possessions in 1558.)

Charles would spend his entire reign battling his own Parliament, with an increasing lack of success, to maintain what he saw as the right and proper prerogatives of the King.  Reign and battle both would culminate in 1649, when a revolution led by Oliver Cromwell first deposed, then executed King Charles I.
