The Territory of Iowa Legislative Assembly or Legislative Assembly of Iowa Territory was the legislature of Iowa Territory, which operated between the creation of the territory in 1838 and statehood in 1846.
Like that of Wisconsin Territory (from which Iowa had been split when Wisconsin became a state), the Assembly consisted of an upper house, called the Council (although some historical compilations refer to it as the Senate), led by a President; and a lower house, the House of Representatives, led by a Speaker of the House.
The Council had 13 members, the House had 26.
[1] The Assembly held eight regular sessions and two special sessions of varying lengths, the first beginning November 12, 1838 and the last ending January 19, 1846.
[2] Throughout the Assembly's duration, members of the Democratic Party held an absolute majority of varying extent in both houses.
