Kansas had but one representative in the U.S. House of Representatives until after the 1870 U.S. Census, which showed that the state was entitled to three members of the lower branch of the national legislature. In 1872, three representatives-at-large were elected, but by the act of March 2, 1874, the legislature divided the state into three districts. The 2nd congressional district was composed of the counties of Montgomery, Wilson, Labette, Cherokee, Crawford, Neosho, Bourbon, Allen, Anderson, Linn, Miami, Franklin, Johnson, Douglas and Wyandotte.
No changes were made in until after the 1880 U.S. Census, which gave the state seven representatives. On March 5, 1883, GovernorGeorge Washington Glick approved an act of the legislature which reduced the 2nd congressional district to only include the counties of Wyandotte, Johnson, Douglas, Miami, Franklin, Anderson, Linn, Allen and Bourbon.
Although the 1890 U.S. Census showed the population of Kansas to be large enough to entitle the state to eight representatives, no additional district was created until 1905. By the act of March 9, 1905, the state was divided into eight districts with the 2nd Congressional district being composed of the counties of Wyandotte, Johnson, Douglas, Miami, Franklin, Anderson, Linn, Allen and Bourbon.
