William Morris Hughes, CH, KC, was an Australian politician who served as the 7th Prime Minister of Australia, in office from 1915 to 1923. He is best known for leading the country during World War I, but his influence on national politics spanned several decades. Hughes was a member of federal parliament from Federation in 1901 until his death, the only person to have served for more than 50 years. He represented six political parties during his career, leading five, outlasting four, and being expelled from three.
Hughes was born in London to Welsh parents. He emigrated to Australia at the age of 22, and became involved in the fledgling labour movement. He was elected to the New South Wales Legislative Assembly in 1894, as a member of the New South Wales Labor Party, and then transferred to the new federal parliament in 1901. Hughes combined his early political career with part-time legal studies, and was called to the bar in 1903. He first entered cabinet in 1904, in the short-lived Watson Government, and was later Attorney-General in each of Andrew Fisher's governments. He was elected deputy leader of the Australian Labor Party in 1914.
