When Henry VIII was engaged in his campaign against Catholicism, he seized church lands and raided monasteries. In the process, his men disturbed and even destroyed the final resting places of the monarchs who came before him. In fact, Henry VIII even likely caused the destruction of the tomb of his namesake: Henry I.
Henry I was the son of William the Conqueror, and reigned for nearly 30 years from 1106 to 1135. Although he crowned himself king in 1100, his reign was disputed by his older brother, Robert, who had been away fighting in the Crusades. Henry initially was able to buy Robert off, but the two later came into conflict again, which was only resolved in 1106 with Henry's army capturing Robert in battle and imprisoning him for life.
Henry spent much of his time away from England, often frequenting Normandy. In order to rule in his absence, he created a bureaucracy that would efficiently govern and run the affairs of state, the most important duty of which was to collect taxes.
Following the death of his son, Henry was left with only one legitimate heir, his daughter. When Henry died in 1135, his daughter's rule was rejected by the English nobility and civil war ensued.
