1868
The Territory of Wyoming was created by Act of Congress. It was formed from land taken from the Dakota, Idaho, and Utah Territories.
1869
Passage of the Suffrage Act in the first session of this year's territorial legislature gave Wyoming the distinction of being the first government within the jurisdiction of the United States to grant women the right to vote.
1890
Wyoming was admitted as the 44th state in the Union and became the first state to grant women full voting rights.
1890
Joseph M. Carey and Francis Warren, both of Cheyenne, presented their credentials and took the oath of office as Wyoming's first U.S. senators. The senators then drew lots to determine their class assignments. Warren drew Class 1, with a term to expire on March 3, 1893. Warren drew Class 2, with a term to expire on March 3, 1895.
1891
Joseph M. Carey became chairman of the Senate Committee on Education and Labor (today's Committee on Health, Education, Labor, and Pensions), a position he held until 1893.
1893
After the politically fragmented state legislature failed to elect a senator for the term beginning March 4, 1893, the state governor appointed Democrat Asahel Beckwith to the vacant seat to serve until the next meeting of the legislature. The states of Washington and Montana experienced similar legislative deadlocks and followed Wyoming's example of sending a temporary gubernatorial appointee. A national economic depression and the regionally sensitive question of whether to remove silver as a basis of the nation's monetary system caused the debate to extend through the summer. On July 11, Beckwith withdrew his claim to a seat to return to managing his coal mining and cattle ranching businesses. In late August, the Senate voted to deny the Montana and Washington claimants their seats. This left all three states without their full Senate representation until early 1895.
1895
Francis Warren returned to take Wyoming's Class 2 Senate seat. He served until his death in 1929 and is Wyoming's longest-serving senator, with a total of 37 years and 4 days.
1905
Francis Warren became chairman of the Senate Committee on Military Affairs (today's Committee on Armed Services), a position he held until 1911 when, on April 27, 1911, Warren became chairman of the Committee on Appropriations. He served as Appropriations chair until 1913.
1916
John Kendrick of Sheridan, a cattle rancher and former governor, became the state's first directly elected senator after the Seventeenth Amendment to the U.S. Constitution went into effect in 1913.
1923
The Committee on Public Lands and Surveys (today's Committee on Energy and Natural Resources) began a series of hearings to investigate the leasing of government oil reserves in Wyoming to oilmen and developers. This became known as the "Teapot Dome" investigation.
1929
Francis Warren died. At the time of his death, Warren had served in the Senate for 37 years, longer than any other member to date. He held two other distinctions: he was the last surviving senator to have served the Union during the Civil War, and he was among the first senators to hire a woman staff member.
1934
Joseph C. O'Mahoney of Cheyenne read George Washington's 1796 Farewell Address on the floor of the Senate, a tradition dating to 1862.
1945
Joseph C. O'Mahoney became chairman of the Senate Committee on Indian Affairs, a position he held until 1947. On January 10, 1949, he became chairman of the Committee on Interior and Insular Affairs (today's Committee on Energy and Natural Resources), a position he held until 1953.
1954
Lester Hunt of Lander read George Washington's 1796 Farewell Address on the floor of the Senate, a tradition dating to 1862.
1954
Several days after announcing his plans to resign from the Senate, Senator Lester Hunt committed suicide in his Senate office building suite. Political foes who sought to punish him for his forthright stand against the anti-communist tactics of his Senate colleague Joseph McCarthy and strove to add another Republican member to the narrowly divided Senate had threatened to publicize his son's 1953 arrest in a male prostitution sting. Hunt's suicide formed the basis of Allen Drury's 1959 Pulitzer Prize winning novel, Advise and Consent.
1958
University of Wyoming history professor Gale McGee of Laramie won a Senate seat in the year's Democratic landslide with the help of his students and without prior governmental service. In this election Democrats gained an unprecedented 16 Senate seats.
1960
The state dedicated its first entry in the National Statuary Hall Collection, a bronze likeness of Esther Hobart Morris. A pioneer in the women's suffrage movement, Morris earned her distinction as the first U.S. woman to serve as a justice of the peace. No decision of hers was ever reversed by appeal to a higher court.
1960
Representative Keith Thomson, 41 and a senator-elect, died before his Senate term began. Democratic governor J. J. Hickey of Cheyenne subsequently resigned from his office so that his successor could appoint him to the vacancy, which ran until the 1962 general election. Hickey lost his 1962 election bid to former Republican governor Milward Simpson of Cody.
1961
Joseph O'Mahoney of Cheyenne ended a 25-year Senate career, making him the second-longest-serving Wyoming senator after Francis Warren, who served more than 37 years.
1977
For the first time since becoming a state in 1890, the Wyoming Senate delegation included two members from the same political party: Republicans Clifford P. Hansen of Jackson and Malcolm Wallop of Big Horn.
1977
Republicans elected Clifford P. Hansen as their Conference secretary, a position he held until his resignation at the end of 1978.
