Source-derived summary

The Purple Gang, also known as the Sugar House Gang, was a criminal mob of bootleggers and hijackers composed predominantly of Jewish gangsters. They operated in Detroit, Michigan, during the 1920s of the Prohibition era and came to be Detroit's dominant criminal gang. Excessive violence and infighting caused the gang to destroy itself in the 1930s.

History

The Michigan Legislature prohibited the sale of liquor in 1917, three years before national Prohibition was established by a constitutional amendment. Along with temperance supporters, industrialist Henry Ford owned the River Rouge plant and desired a sober workforce, so he backed the Damon Act, a state law that, along with the Wiley Act, prohibited virtually all possession, manufacture, or sale of alcohol starting in 1918. Detroit is close to Ohio, so bootleggers and others would import liquor from Toledo where it was still legal. They also smuggled liquor in from Canada.

Judges took a lenient view of offenders. The Damon Act was declared unconstitutional in 1919 by the state supreme court.

In 1920, the Eighteenth Amendment was adopted and prohibition took effect throughout the United States.

Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Purple Gang”, the useful work is to connect “criminal mob group of the 1920s” to the records capable of establishing context and consequence.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 24, 2026. The linked authority identifier is Q1526970. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1917, 1918, 1919 and 1920.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
