After the war, under the leadership of Governors Frank G. Clement and Buford Ellington, the state gave increased attention to education, mental health, highways, and constitutional reform, and Tennessee became a testing ground for breaking the barriers of racial segregation in schools and in other public facilities. Knoxville, Chattanooga, Nashville, and Memphis were sites of important protests by African Americans against segregation. The sit-ins in Nashville in 1959ā61 gained national attention for the civil rights movement, as did the Memphis sanitation workersā strike in 1968. Civil rights leader Martin Luther King, Jr., was in Memphis to support the sanitation workers when he was assassinated on April 4 of that year; a Tennessee court subsequently convicted James Earl Ray of the murder.
After the 1960s, Tennesseans experienced the revitalization of two-party politics. Republicans, who after Reconstruction had typically held strength only in East Tennessee, began to acquire more supporters among Middle and West Tennesseans. Since the 1970s neither party has dominated the office of governor, though since about the mid-1990s the Tennessee delegation to the U.S. House of Representatives has been primarily Republican, and since 1995 both of the stateās U.S. senators have been Republicans. One of Tennesseeās last Democratic senators, Al Gore, also served as vice president (1993ā2001) and was the Democratic candidate in the 2000 presidential election.
Since the turn of the 21st century, Tennessee has experienced steady population growth, concentrated heavily in the suburban areas of the major cities. The population increased by a total of 27 percent between 2000 and 2024. The overall ethnic composition of the state generally has been maintained, although the Hispanic community has expanded to form 8 percent of the total. The service sector of the economy has performed strongly in the areas of shipping, hotels and entertainment, and health care, while the production of automobiles has bolstered the stateās manufacturing industry.
