Tony Blair's emergence as a Labour Party leader in 1994 British politics marked a seismic shift for England. By 1997 he had transformed his party and become prime minister bringing to an end eighteen years of Conservative government while guiding Labour for three terms. During his tenure he dealt with the death of Princess Diana, the war on terror, negotiations for peace in Northern Ireland, reforms to British public service areas, and constant meetings with leaders on the world stage over issues that affected the entire world.
