Huey Pierce Long Jr. (August 30, 1893 – September 10, 1935), nicknamed "The Kingfish", was an American politician who served as the 40th governor of Louisiana from 1928 to 1932 and as a United States senator from 1932 until his assassination in 1935. He was a left-wing populist member of the Democratic Party and rose to national prominence during the Great Depression for his vocal criticism of President Franklin D. Roosevelt and his New Deal, which Long deemed insufficiently radical. As the political leader of Louisiana, he commanded wide networks of supporters and often took forceful action. A controversial figure, Long is celebrated as a populist champion of the poor or, conversely, denounced as a fascistic demagogue.
Long was born in the impoverished north of Louisiana in 1893. After working as a traveling salesman and briefly attending three colleges, he was admitted to the bar in Louisiana. Following a short career as an attorney, in which he often represented poor plaintiffs, Long was elected to the Louisiana Public Service Commission. As commissioner, he prosecuted large corporations such as Standard Oil, a lifelong target of his rhetorical attacks.
