In 1924, the Ku Klux Klan held a conference and planned a parade from its local headquarters at 230 S. Michigan St. In preparation, Klan members were posted around town to direct traffic. Notre Dame students, well aware of the anti-Catholic nature of the Klan, vigorously protested this intrusion, and before noon all of the Klansmen traffic directors had been "unmasked and unrobed."

Later business Other industries developed in South Bend in the early 20th century, including Birdsell Manufacturing Company, the Bendix Corporation, Honeywell, AlliedSignal, South Bend Lathe Works, the O'Brien Paint Corp., the South Bend Toy Company, South Bend Range, South Bend Bait Company, and South Bend Watch Company.

Recent history On September 29, 1929, South Bend completed its "track elevation program". This was a railroad infrastructure project which saw the removal of Grand Trunk Western Railroad tracks from Division Street, the removal of level crossings from Chapin to Miami streets, the creation of a modern freight layout, and the construction of Union Station. This project had been seventeen years in the making, and had been the subject of the Indiana Supreme Court case Vandalia Railroad v. South Bend, which was subsequently affirmed by the Supreme Court of the United States. In 1949, legendary percussionist Lionel Hampton was informed that his concert at South Bend's Palais du Royale would be a blacks-only event; he threatened to call for a boycott of the venue, and the
