Michigan outlawed the death penalty in 1847. Technically the penalty was still permitted for treason but after it was outlawed 1847 no executions were carried out for this or any other reason under Michigan law; the US Government hanged a man in Michigan in 1938, for a murder he had committed while robbing a federal bank but this was under federal law and federal penalty. Michigan included the ban on the death penalty formally in its constitution in 1963. Wisconsin banned the death penalty - for all charges - in 1853, two years after the only execution in its history since joining the Union of the states in 1848. Maine abolished the death penalty in 1876, re-established it for murder in 1883, and finally abolished it permanently in 1887; multiple attempts since to reinstate it for various crimes have not succeeded. Minnesota abolished the death penalty in 1911; there were 23 attempts between 1913 and 2005 to reinstate it for various crimes but none succeeded here either. A total of 22 states, plus the District of Columbia and Puerto Rico have abolished the death penalty for all crimes. In 2020, the death penalty is used in the US by 28 states, the federal government, and the military. The US is one of 55 countries worldwide which apply the penalty.
