context_page_description: Since Montana became a U.S. state in 1889, it has sent congressional delegations to the United States Senate and the United States House of Representatives. Each state elects two senators to serve for six years. Before the Seventeenth Amendment took effect in 1913, senators were elected by the Montana State Legislature. Members of the House of Representatives are elected to two-year terms, one from Montana's at-large congressional district. Before becoming a state, the Territory of Montana elected a non-voting delegate at-large to Congress from 1864 to 1889.
  A total of 54 people have served either the Territory or State of Montana: 17 in the Senate, 32 in the House, and five in both houses. The longest-serving senator is Max Baucus, in office from 1978 to 2014. The longest-serving representative is Pat Williams, in office for 18 years from 1979 to 1997. One woman has been a member of Montana's congressional delegation, Jeannette Rankin, as a representative. She was the first woman in the United States Congress.
context_section_description: Members of the House of Representatives are elected every two years by popular vote within a congressional district. Montana currently has an at-large congressional district that represent the entire state. Every ten years, the number of congressional districts is reapportioned based on the state's population as determined by the United States Census; Montana had had two districts from 1913 to 1993.
  There have been 34 people, including just one woman, who have served as representatives from Montana: 15 Democrats, 18 Republicans and 1 Populist. Greg Gianforte is the current officeholder.
