Charles I (19 November 1600 – 30 January 1649) was monarch of the three kingdoms of England, Scotland, and Ireland from 1625 until his execution in 1649. The second son of King James VI of Scotland, he spent most of his life in England after his father inherited the English throne in 1603. His reign was marked by quarrels with the Parliament of England, which sought to curb his royal prerogative. From 1642, Charles fought the armies of the English and Scottish parliaments in the English Civil War. His defeat led to his execution, followed by establishment of a republic called the Commonwealth of England.
This painting, titled Equestrian Portrait of Charles I, is an oil-on-canvas work by Charles's Principal Painter in Ordinary, Anthony van Dyck. The portrait, now in the National Gallery in London, is thought to have been painted in about 1637–38, and is one of many portraits of Charles by van Dyck, including several equestrian portraits.Painting: Anthony van Dyck
