Prohibition Era: Detroit's Smuggling Hotspot

During Prohibition (1920–1933), Detroit’s close proximity to Canada turned the city into a smuggler’s paradise. The Detroit River became the ultimate bootlegging highway, connecting Windsor, Ontario, to thirsty Americans. It’s estimated that a staggering 75% of all alcohol smuggled into the U.S. during this time came through the Detroit-Windsor corridor (Des Moines Register). With its hidden tunnels, secret river crossings, and thriving underground market, Detroit earned its place as a central player in America’s wild Prohibition story.
