1495 - Great Excommunication

and in this year, the Friday the ninth of January, Master Adam Moleyns, Bishop of Chichester and Keeper of the Kings Privy Seal, whom the king sent to Portsmouth to make payment of money to certain soldiers and shipmen for their wages. And it so happened that with boisterous language, and also for the abridging of their wages, he fell in variance with them and they fell on him and they cruelly killed him. They did indeed. They took him out of the Domus Die, (Garrison Chapel) on to what is now the Parade Ground, and there they stoned him to death.” For this terrible crime the citizens of Portsmouth with the guilty soldiers and sailors, fell under the ban of Excommunication that was to lie upon the town for nearly half a century. The implications of excommunication were disastrous for the town and would have consequences for its growth. However it did not deter Henry VII from developing the Dockyard or the town defences.
