In Howard's third term in office, Australia contributed troops to the War in Afghanistan and the Iraq War, and led the International Force for East Timor. The Coalition would be re-elected once more at the 2004 federal election. In his final term in office, his government introduced industrial relations reforms known as WorkChoices, which proved controversial and unpopular with the public. The Howard government was defeated at the 2007 federal election, with the Labor Party's Kevin Rudd succeeding him as prime minister. Howard also lost his own seat of Bennelong at the election to Maxine McKew, becoming only the second prime minister to do so, after Stanley Bruce at the 1929 election. Following this loss, Howard retired from politics, but has remained active in political discourse.
Howard's government presided over a sustained period of economic growth and a large "mining boom", and significantly reduced government debt by the time he left office. He was known for his broad appeal to voters across the political spectrum, and commanded a diverse base of supporters, colloquially referred to as his "battlers". Retrospectively, ratings of Howard's premiership have been polarised. His critics have admonished him for involving Australia in the Iraq War, his policies regarding asylum seekers, and his economic agenda. Nonetheless, he has been frequently ranked within the upper-tier of Australian prime ministers by political experts and the general public.
