Utah Territory was established in September 1850, and it permitted condemned prisoners to choose between hanging and firing squad. In 1851 beheading was introduced as a third execution option. No prisoner chose this method and the option was eliminated in 1888. In 1955, Utah state lawmakers voted to introduce the electric chair; however, the state never used electrocution due to failure to provide appropriation. Forty-four executions occurred in the State of Utah and Utah Territory before the national moratorium in 1967; six were by hanging and 38 were by firing squad. The last pre-moratorium execution in Utah took place on March 30, 1960.
