The East Tennessee Convention was an assembly of pro-Union delegates primarily from East Tennessee that met on three occasions during the U.S. Civil War. The Convention most notably declared the secessionist actions taken by the Tennessee state government on the eve of the war unconstitutional, and requested that East Tennessee, where Union support remained strong, be allowed to form a separate state that would remain part of the United States. The state legislature denied this request, and the Confederate Army occupied the region in late 1861.
The Convention first met in Knoxville on May 30–31, 1861, in response to the state government's "Declaration of Independence" from the United States and formation of a military league with the Confederacy. Congressman T.A.R. Nelson was elected president of the Convention, and resolutions were adopted denouncing the state government's actions. The Convention met for the second time in Greeneville from June 17 to June 20, 1861, after Tennessee had voted to secede from the Union. This second meeting produced a memorial to the state government requesting East Tennessee be allowed to separate from Tennessee. The Convention met for a final time in Knoxville from April 12 to April 16, 1864, to address the Emancipation Proclamation and the ten percent plan. This final meeting was marked by bitter divisions over the issue of slavery.
Although it failed in its goal of establishing a Union-aligned state in East Tennessee, the Convention played an important role in solidifying leadership and unity of purpose for the region's Unionists. Many of its delegates would serve in federal, state and local offices during the postwar period.
Throughout the first half of the 19th century, East Tennessee was frequently at odds with Tennessee's two other grand divisions, Middle Tennessee and West Tennessee. Many East Tennesseans felt the state legislature showed persistent favoritism toward the other two divisions, especially over funding for internal improvements. In the early 1840s, several East Tennessee leaders, among them Congressman (and future President) Andrew Johnson, led a movement to form a separate state in East Tennessee known as "Frankland." Though this movement was unsuccessful, the idea that East Tennessee should be a separate state periodically resurfaced over the subsequent two decades.
