His ideas were just as inflammatory as those of Tom Paine and local politicians attacked Priestley, which led to an angry mob breaking into his house and burning most of his Papers and equipment. He fled the city and moved to London where he took up a teaching post at New College in Hackney. He was among a number of radicals that preached in the Newington Green Unitarian Chapel. He was, however, just as unpopular with the local population in London as he had been in Birmingham.
