developed, including Metz, Storz and Krug companies. The city's southern suburb became home to the Strategic Air Command in the late 1940s; in 1950 the Rosenblatt Stadium in South Omaha became home to the College World Series. Labor unrest in the 1930s resulted in organizing of the meatpacking plants by the CIO-FCW, which built an interracial partnership and achieved real gains for the workers for some decades. After World War II, blacks in Omaha as in other parts of the nation began to press harder for civil rights. Veterans believed they deserved full rights after fighting for the nation. Some organizations had already been formed, but they became more active, leading into the city's Civil Rights Movement. Suburbanization and highway expansion led to white flight to newer housing and development of middle and upper-class areas in West Omaha from the 1950s through the 1970s. The historically ethnically diverse areas of North and South Omaha became more concentrated by economics, race, and class. These workers suffered dramatic job losses during the industrial restructuring that increased rapidly in the 1960s, and poverty became more widespread. White contact with Native Americans Omaha's location near the confluence of the Missouri River and Platte River has long made the location a key point of transfer for both people and goods. Prior to European-American establishment of the city, numerous Indian tribes had inhabited the area, including the Pawnee, Otoe, Sioux, the Missouri and Ioway. They had developed a semi-nomadic lifestyle necessary for survival on the Great Plains. Since the 17th century, the Pawnee, Otoe, Sioux, and Ioway all variously occupied the land that became Omaha. The Pawnee and Otoe tribes had inhabited the region for hundreds of years by the time the Siouan-language Omaha tribe had arrived from the lower Ohio valley in the early 18th century. Translated, the word "Omaha" () means "Dwellers on the Bluff". Usually, the word is translated "against the current," but in those cases no source is quoted. During the late 18th and early 19th centuries when they were the most powerful Indians along the stretch of the Missouri River north of the Platte, the Omaha nation moved on the western edge of present-day Bellevue, Nebraska. After a smallpox outbreak, cultural degradation, the elimination of the buffalo, and continued property loss, the Omaha sold the last of their claims in 1856 and relocated to their present reservation in Thurston County, in
