Cobb County was one of nine Georgia counties carved out of the disputed territory of the Cherokee Nation in 1832. It was the 81st county in Georgia and named for Judge
Thomas Willis Cobb, who served as a U.S. Senator, state representative, and superior court judge. It is believed that the county seat of Marietta was named for Judge Cobb's wife, Mary. The state started acquiring
right-of-way for the
Western & Atlantic Railroad in 1836. A train began running between Marietta and
Marthasville (modern-day Atlanta) in 1845. During the
American Civil War, some
Confederate troops were trained at a camp in Big Shanty (now Kennesaw), where the
Andrews Raid occurred, starting the
Great Locomotive Chase. The
Battle of Allatoona Pass on October 5, 1864, occurred as Sherman was starting his
march through Georgia. Union forces burnt most houses and confiscated or burnt crops. The
Battle of Kennesaw Mountain on June 27, 1864, was the site of the only major Confederate victory in General
William T. Sherman's invasion of Georgia. Despite the victory, Union forces outflanked the Confederates. In 1915,
Leo Frank, the Jewish supervisor of an Atlanta pencil factory who was convicted of murdering one of his workers, thirteen-year-old Mary Phagan, was kidnapped from his jail cell and brought to Frey's Gin, east of Marietta, where he was lynched. Cotton farming in the area peaked from the 1890s through the 1920s. Low prices during the
Great Depression resulted in the cessation of cotton farming throughout Cobb County. The price of cotton went from 16¢ per pound (35¢/kg) in 1920 to 9½¢ (21¢/kg) in 1930. This resulted in a cotton bust for the county, which had stopped growing the product but was milling it. This bust was followed by the
Great Depression. To help combat the bust, the state started work on a road in 1922 that would later become
U.S. 41, later replaced by
Cobb Parkway in the late 1940s and early 1950s. –

Marietta Army Airfield, 1946 In 1942, Bell Aircraft opened a Marietta plant to manufacture
B-29 bombers and
Marietta Army Airfield was founded. Both were closed after World War II but reopened during the
Korean War when the Air Force acquired the airfield, renamed Dobbins AFB, and the plant by
Lockheed. During the Korean and
Vietnam Wars, Lockheed Marietta was the leading manufacturer of military transport planes, including the
C-130 Hercules and the
C-5 Galaxy. "In Cobb County and other sprawling Cold War suburbs from
Orange County to
Norfolk/
Hampton Roads, the direct link between federal defense spending and local economic prosperity structured a bipartisan political culture of hawkish conservatism and material self-interest on issues of national security." When county
home rule was enacted statewide by
amendment to the
Georgia state constitution in the early 1960s,
Ernest W. Barrett became the first chairman of the new
county commission. The county
courthouse, built in 1888, was demolished, spurring a law that now prevents counties from doing so without a
referendum. In the 1960s and 1970s, Cobb
transformed from rural to suburban, as integration spurred
white flight from the city of Atlanta, which by 1970 was majority-African-American. Real-estate booms drew rural white southerners and
Rust Belt transplants, both groups mostly first-generation
white-collar workers. Cobb County was the home of former segregationist and Georgia governor
Lester Maddox (1966–71). In 1975, Cobb voters elected
John Birch Society leader
Larry McDonald to Congress, running in opposition to
desegregation busing. A
conservative Democrat, McDonald called for investigations into alleged plots by the
Rockefellers and the
Soviet Union to impose "socialist-one-world-government" and co-founded the
Western Goals Foundation. In 1983, McDonald died aboard
Korean Air Lines Flight 007, shot down by a Soviet fighter jet over restricted airspace. I-75 through the county is now named for him. In 1990, Republican Congressmen
Newt Gingrich became Representative of a new district centered around Cobb County. In 1994, as Republicans took control of the U.S. House of Representatives for the first time in almost fifty years, Gingrich became
Speaker of the House, thrusting Cobb County into the national spotlight. In 1993, county commissioners passed a resolution condemning homosexuality and cutting off funding for the arts after complaints about a community theater. After protests from gay rights organizations, organizers of the
1996 Summer Olympics pulled events out of Cobb County, including the
Olympic Torch Relay. The county's inns were nevertheless filled at 100% of capacity for two months during the event. In the 1990s and 2000s, Cobb's demographics changed. As Atlanta's
gentrification reversed decades of white flight, middle-class African-Americans and Russian, Bosnian, Chinese, Indian, Brazilian, Mexican, and Central American immigrants moved to older suburbs in south and southwest Cobb. In 2010, African-American Democrat
David Scott was elected to
Georgia's 13th congressional district, which included many of those suburbs. Cobb became the first Georgia county to participate in the
Immigration and Nationality Act Section 287(g) enabling local law officers to enforce immigration law. ==Geography==
