The Alabama Territory[n] was designated by two interdependent Acts of the Congress of the United States, passed by both chambers, the Senate and the House of Representatives on March 1 and 3, 1817,[3][4] but it did not become effective until October 10, 1817.
[1][5][6] The delay was due to a provision in the Congressional Organic Act passed in Washington, which stated that the act would only take effect if and when the western part of the Mississippi Territory (1798–1817) were to form a state constitution and government on the road to statehood.
A state constitution for Mississippi was drawn up and adopted by Mississippian delegates on August 15, 1817, elections were held the next month in September, and the first legislative session convened in October,[1] with the western part of the Mississippi Territory existing since 1798 becoming the State of Mississippi on December 10, 1817.
William Wyatt Bibb (1781–1820), formerly of Georgia was the only territorial governor, later elected to that position after achieving statehood.
On December 14, 1819, Alabama was admitted to the federal Union as the 22nd state,[5][8] with appointed territorial governor William W. Bibb (1781-1820), formerly of &Georgia, becoming the elected first state governor (1819–1820).
