William Marshal, first earl of Pembroke, died in 1219 as King regent. Subsequently, because of his commitment to the Templers cause in the Holy Land, and his loyalty to the English royal family, he was buried in Temple Church with great honor. His effigy tomb, despite being partially destroyed during "The Blitz," remains untouched in Temple Church.
Temple Church was opened in 1185, and became the stronghold of the Knights Templar order in England. Today it serves as the final resting place for William Marshal alongside notable Templar leaders. Most of the building remains as it was in the 12th century with significant restoration taking place after "The Blitz" in World War II.
There are many different versions of the Magna Carta. This is version is the first ever version, signed by King John in Runnymede in 1215. William Marshal had significant influence in the signing of this version.
