Mexico, was rejected by most Arizonans. Progressives in Arizona favored inclusion in the state constitution of the initiative, referendum, recall, direct election of senators, woman suffrage, and other reforms. Most of these proposals were included in the constitution that was rejected by Congress. A new constitution was offered with the problematic provisions removed. Congress then voted to approve statehood, and President Taft signed the statehood bill on February 14, 1912. State residents promptly put the provisions back in. Hispanics had little voice or power. Only one of the 53 delegates at the constitutional convention was Hispanic, and he refused to sign. In 1912 women gained suffrage in the state, eight years before the country as a whole. Arizona's first Congressman was Carl Hayden (1877–1972). He was the son of a Yankee merchant who had moved to Tempe because he needed dry heat for his bad lungs. Carl attended Stanford University and moved up the political ladder as town councilman, county treasurer, and Maricopa County sheriff, where he nabbed Arizona's last train robbers. He also started building a coalition to develop the state's water resources, a lifelong interest. A liberal Democrat his entire career, Hayden was elected to Congress in 1912 and moved to the Senate in 1926. Reelection followed every six years as he advanced toward the chairmanship of the powerful Appropriations Committee, which he reached in 1955. His only difficult campaign came in 1962, at age 85, when he defeated a young conservative. He retired in 1968 after a record 56 years in Congress. His great achievement was his 41-year battle to enact the Central Arizona Project that would provide water for future growth. The Great Depression The Great Depression of 1929–39 hit Arizona hard. At first local, state and private relief efforts focused on charity, especially by the Community Chest and Organized Charities programs. Federal money started arriving with the Federal Emergency Relief Committee in 1930. Different agencies promoted aid to the unemployed, tuberculosis patients, transients, and illegal immigrants. The money ran out by 1931 or 1932, and conditions were bad until New Deal relief operations began on a large scale in 1933. Construction programs were important, especially the Hoover Dam (originally called Boulder Dam), begun by President Herbert Hoover. It is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border with Nevada. It was constructed by the Federal Bureau of Reclamation
