In this vibrantly coloured portrait, Charles I is wearing the ribbon and badge of the Order of the Garter, which depicts St George on horseback slaying a dragon. The painting is believed to be a copy of a full-length portrait by the Dutch artist Daniel Mytens, who was the principal painter at the Stuart court from the early 1620s to the mid-1630s. Charles was defeated in the English Civil War (1642 - 51) and was tried for treason in Westminster Hall in January 1649. Convicted, he was sentenced to death.
