1846-1848
The Mexican War began in 1846 and ended in 1848 with the signing of the Treaty of Guadalupe Hidalgo. Mexico agreed to cede much of the American southwest to the United States in exchange for $15 million dollars. This territory included the future state of Utah.
1850
As part of the Compromise of 1850, Senator Henry Clay introduced the Utah territorial bill, allowing for the establishment of a territorial government in Utah. The Utah Territory was established by Congress on September 9, 1850.
1862
The Senate passed the Anti-Bigamy Act, aimed at Utah Mormons. This legislation banned multiple marriages and disincorporated the Mormon Church’s structure. It was laxly enforced by the federal government as a result of the Civil War while Mormon control of Utah courts further stalled enforcement of the law in the Utah territory.
1870
The territory of Utah granted women the right to vote. That right was taken away by the Edmunds-Tucker Act of 1887, but in 1895, the right for women to vote and to hold public office was written into the state constitution.

1896
Senator Frank Cannon switched parties to become a Silver Republican. Silver Republicans split with the Republican Party over the fight for free silver versus the gold standard.

Frank Cannon lost his campaign for reelection. Utah had only one senator for the next two years as the legislature failed to elect a new senator.
1903
Reed Smoot, a Republican from Provo and a leader in the Mormon Church, replaced Joseph Rawlins in the Senate. As soon as he arrived in Washington he faced his first controversy. His credentials as a senator were challenged on the grounds that his religious beliefs made it impossible for him to faithfully execute his position as senator. The Senate decided to seat him but launched an investigation into the matter.
1906
Former senator Arthur Brown was murdered by his mistress in an ugly and bizarre incident. Brown was working in Washington, D.C., as a lawyer when he received notice from his alleged mistress that she believed he should marry her because he was the father of her child. The woman implored him to “do the right thing.” He refused to marry her, and in response, she took a train to Washington and shot him. Brown was shot on December 8 and died four days later.

It was popularly blamed for prolonging and exacerbating the Great Depression.
