Oliver Cromwell died at Whitehall on September 3rd, 1658. His death mask is on display in the Museum of London.
He was buried in Westminster Abbey, but when the Royalists returned to power his corpse was dug up, hung in chains, and beheaded.
His measures against Irish Catholics have been characterized by some historians as genocidal or near-genocidal, and in Ireland itself he is widely hated.
Gosh, this story is gruesome. I guess he deserved the treatment he received after his death. We have to pay sooner or later for our mean behaviors…
