Dade County, GA
History
Dade County was established in 1837 and was named for Major Francis Langhorne Dade, who was killed in the Dade Massacre by Seminole Indians in December 1835. The first settlers of Dade County won the land in the Georgia Land Lotteries, held to encourage settlement after the Cherokee people were forced off the land. Many settlers worked in regional coke and coal mines that contributed to development of the Chattanooga, Tennessee area.The area was long isolated from the rest of Georgia by its geography of mountains and rivers, which some historians say contributed to early residents' separatist attitudes. Georgia did not have a road connecting Dade County to the rest of the state until the establishment of Cloudland Canyon State Park in 1939. That year Georgia began work on Highway 136 to connect U.S. 41 to the recently created park. The Civilian Conservation Corps built many of the facilities and access roads to the park. Up until then, travelers from elsewhere in Georgia could drive to the county only by way of Alabama or Tennessee.
Dade County had a short-lived state secessionist movement before the American Civil War. In 1860, county residents wanted to secede from the Union, but lawmakers for the state of Georgia were cautious. Legend has it that in 1860, the people of Dade County were so impatient that they announced their own secession from both Georgia and the United States. On July 4, 1945, a telegram from President Harry S. Truman was read at a celebration marking the county's "rejoining" the Union. Historians say Dade's individual secession and readmission were symbolic and had no legal effect. They say that officially, Dade County seceded along with the state of Georgia in 1861 and re-entered the Union with the state in 1870.
