There were two periods in this country when there was a sustained increase in homicide rate for an extended period of time. The first was from 1903 to 1933. This corresponds to the first prohibition. First alcohol was prohibited in several of the states in the early 20th century. The federal government made hard narcotics illegal in 1914 and alcohol illegal in 1918. The increase in homicide rates stopped the year that the prohibition of alcohol ended.
