On this day in 1909, on land previously inhabited by the native Omaha people until smallpox and a series of broken promises and treaties with the U.S. pushed them north to reservations, a mob of 1000 – 3000 Western European immigrants enter the Greek Town neighborhood of South Omaha, Nebraska, entering and looting homes, beating up Greek immigrants, and telling them to leave the city by sundown. Two days earlier, a Greek immigrant had shot and killed a police officer who was arresting him after being accused of coercing his English teacher into having sex. Wide-spread resentment of Greek immigrants turns hostile. Nearly all of the 3000 Greeks living in South Omaha move out. Anti-Greek riots erupt in other cities in the region.
