From its admittance as a state in 1890 to 1913, Idaho was represented in the United States House of Representatives by one at-large representative. After the 1910 census Idaho was awarded a second seat starting with the 63rd Congress in 1913. However both seats continued to be elected at-large on a general ticket until the election of 1918. Since that year the state has allocated two districts for its representatives.
