1791: Priestley’s writings defended the French Revolution and he forms the Constitutional Society in Birmingham. His ideas were just as inflammatory as those of Tom Paine and local politicians attacked Priestley, which leads to an angry mob breaking into his house and burning most of his papers and equipment. He flees the city and moves to London where he takes up a teaching post at New College in Hackney. He is among a number of radicals that preach in the Newington Green Unitarian Chapel. He is, however, just as unpopular with the local population in London as he had been in Birmingham.
