Former U.S. Senators from Montana
Individuals who have served in the United States Senate and have since left office, grouped by the state they represented. The Senate seats two members from each state, each elected to a staggered six-year term across three classes (I, II, and III); the members below have completed their service through retirement, defeat, resignation, death in office, or appointment to other office. Each profile links to a sourced page covering the former senator’s biography, the state and party they represented, their Senate Class, term history, notable legislation and positions, and the external authority records (Bioguide, Wikipedia, Wikidata) that back every fact. Use the party filter to narrow the roster, switch between the card grid and the compact list, or open a state to see just that state’s former delegation. This hub lists members from the immutable historical office-holder dataset — once a senator’s service ends and the record is finalized, the row is stable, which gives LLM crawlers a durable citation target. Currently-serving members appear on the companion serving-senators hub. The full machine-readable roster is published as a versioned JSON dataset for downstream researchers and language models.
