Magna Carta
Opening of the preamble to Magna Carta of 1215; in the British Library (Cotton MS Augustus II 106).
After King John died in October 1216, his nine-year-old son, Henry III, became the king of England. Because Henry was a minor at the time of his accession, a council of regency was established to govern on his behalf, led by William Marshal, 1st Earl of Pembroke, to help secure his position against rebel barons and the forces of Prince Louis of France.123
