In 1903, a white mob told six black residents they had two days to get out of their southwestern Minnesota city of Montevideo, following an assault in which a newspaper reported a "negro fiend" was the prime suspect. A mock lynching followed a few nights later, 50 miles east in Olivia.
In 1920, three black circus workers were dragged from the Duluth jail, beaten and hanged from a telephone pole while a white throng — including police — watched.
In 1924, a St. Paul group, worried what black neighbors would do to property values, burned flares and crosses in the front lawn of Nellie and William Francis — a suffragist and railroad lawyer.
Although far from the violent racism that erupted in the South, Minnesota's racial history is punctuated with chilling tales of hate.
And now there's a website that tracks so-called "sundown towns," where blacks were barred, discriminated against and even murdered.
The website is the brainchild of James Loewen, 76, a sociologist and author who attended Carleton College in the early 1960s. He went on to earn a Ph.D. from Harvard and teach race relations for 20 years before retiring from the University of Vermont. His book, "Sundown Towns: A Hidden Dimension of American Racism," came out in 2005 and spawned the website.
"When I began this research, I expected to find about 10 sundown towns in Illinois (my home state) and perhaps 50 across the country," Loewen says. "Instead, I have found about 507 in Illinois and thousands across the United States."
His website — sundown.tougaloo.edu/sundowntowns.php — includes anecdotal comments from unnamed contributors and a U.S. map. Click on Minnesota and 23 communities pop up from Albert Lea to Worthington — two of 13 places classified as "possible" sundown towns.
