Charles I of England
Charles came to England in 1604. When Charles's older brother Henry Frederick died in 1612, Charles became the Prince of Wales and the heir apparent to his father's kingdoms. He had an elder brother, Henry, who was clever, handsome, popular, and rich, and next in line for the throne.  Henry died suddenly in 1612, and then his brother Charles was made Prince of Wales in his place, showing that he was now the heir to the throne.  Charles was less suited to be king than Henry had been, because he was small and weak and not as clever.
