Charles I wore white to his coronation, which was considered bad luck, since white clothes were sometimes used by royals as mourning. Â After the execution, his body was brought to Windsor for burial; the black cloth that covered his coffin became covered with snow during the journey. Â This reminded people of his coronation outfit, and led to his posthumous nickname of the White King.
After Charles set up his Standard in 1642, it was blown down during the night.
While Charles was being held prisoner after the Civil War ended, one of the beds he slept in had a motto emblazoned on it:  “Remember thy end.”
During Charles’s trial, the head of his cane fell off.
In 1688, William of Orange landed in England on the 83rd anniversary of the Gunpowder Plot. Â It was also his birthday. Â
William’s supporters wore orange scarves, feathers, and ribbons.  The troops of the Earl of Essex, who commanded Parliament’s army during the first years of the Civil War, wore “tawny” or orange scarves, feathers and ribbons.
William III died from complications from a broken collarbone. He broke his collarbone after being thrown while riding a horse that he had confiscated from the estate of a Jacobite, Sir John Fenwick, whom he had recently executed.
