The revolt grew out of the increasing severity of the poll taxes imposed on the people of England. The Kentish rebels led by Wat Tyler met with those from Essex at Blackheath. It was here that the preacher, John Ball gave his dangerous sermon. Another group of rebels stormed the Tower of London, and executed those who were hiding there, including the Lord High Treasurer and the Archbishop of Canterbury. Tyler's group moved on to Smithfield with the intention of negotiating with King Richard II, but a dispute broke out and Tyler was summarily executed by William Walworth. The nobility subsequently summoned a militia of about 7,000 and restored order.
