Many jurisdictions limited imposition of the death penalty, no government had formally abolished capital punishment until Michigan did so in 1846. Within 20 years Venezuela (1863) and Portugal (1867) had formally eliminated the practice as well.

(A commutation substitutes a lesser penalty for a more severe one-for example, replacing execution with a life sentence.) Today in many nations, including Turkey and Japan, the death penalty remains legal but the number of executions has declined over time.
The defeat of the Axis powers provided a foundation for the elimination of the death penalty in Western Europe. Some of the nations involved in the war saw abolition of capital punishment as a way to disassociate themselves from the atrocities that had taken place. Italy formally abolished the death penalty in 1947 and the Federal Republic of Germany did so in 1949. The British government instituted a Royal Commission to study capital punishment in 1950 and abolished the death penalty in 1965. (Northern Ireland did not abolish capital punishment until...
