Upon assuming the duties of the governor's office in July, 1819, Territorial Secretary Robert Crittenden issued a proclamation calling a session of the territorial legislature at Arkansas Post for July 28, 1819. The only other act of any real importance performed by him during the nearly six months that he was acting governor, before Governor James Miller arrived, was the calling of a general election for November 20, 1819. At this first election five members of a legislative council one from each of the five organized counties and nine members of a house of representatives were elected, besides a territorial delegate to Congress. In authorizing the selection by popular vote of the members of a legislative council, Crittenden overreached his authority. The law which prescribed the mode of government for the Territory, as then constituted, plainly provided that the people should elect by popular choice a house of representatives; the members of this house should then meet, at such time as the governor should appoint, select the names of eighteen persons whom they deemed qualified for the office of councilmen and forward the whole list of those so nominated to the President of the United States. Upon receiving such a list of nominations, it was the duty of the President to appoint nine of the same to be members of the council. Whether Crittenden's error was due to ignorance or imprudence is uncertain. But, at all events, owing to the good sense and prudent statesmanship of Governor Miller, Congress was induced to pass a special Act, which the President approved April 21, 1820, making the election of the councilmen, in the manner authorized by Crittenden, legal after the fact in April after the election in November. Thus Arkansas was raised from a Territory of the first grade one with a legislative council whose members were to be appointed by the President to a Territory of the second grade, in which members of both branches of the territorial legislature were elected by the people themselves.
1st General Assembly
On December 29, 1819, Governor Miller issued his proclamation calling a special session of the General Assembly for the first Monday in February, 1820, to meet at Arkansas Post. Accordingly, the first legislature elected by the people convened February 7, 1820. The council organized by electing Edward McDonald president, and Richard Chamberlain clerk. William Stevenson was chosen speaker of the house and Jason Chamberlain, clerk. Stevenson resigned the day after his election and Joseph Hardin was elected to fill the vacancy. The two houses continued in session until February 24, when they adjourned to meet again on the first Monday in October, which was October 2. This adjourned session lasted until October 25, 1820. At the adjourned session in October, the most notable Act passed was that removing the seat of government to Little Rock, the Act to take effect June 1, 1821.
2nd General Assembly
Members of the second General Assembly were elected August 6, 1821. They met in regular session October 1, 1821, at Little Rock. Sam C. Roane was elected president of the legislative council ; Richard Searcy, secretary. William Trimble was elected speaker of the house of representatives ; Ambrose H. Sevier, clerk. The laws passed were, for the most part, measures of local character. The most important Act of the session, perhaps, was that changing the manner of voting at general elections from ballot to Viva voce. On account of the absences of Governor Miller, who had gone to New Hampshire on business, Robert Crittenden was acting governor during the session, which adjourned October 24, 1821.
3rd General Assembly

Members of the fourth General Assembly were elected August 1, 1825. They met in regular session October 3, 1825. The session lasted until November 3, following. Jacob Barkman was elected president of the legislative council; Thomas W. Newton, secretary. Hobart Bean was speaker of the house; David Barber, clerk.
5th General Assembly
Members of the fifth General Assembly were elected August 6, 1827. They met in regular session, October 1, 1827. Daniel T. Witter was elected president of the council; Thomas W. Newton, secretary. Ambrose H. Sevier was speaker of the house; Andrew Roans, clerk. The session adjourned October 31, 1827. The fifth General Assembly held a special session from October 6 until October 22, 1828. At this session, Sevier, who had been elected delegate to Congress in December, 1827, to fill the vacancy caused by the death of Henry W. Conway, was succeeded by Edwin T. Clark, as president of the legislative council. Daniel T. Witter, who had been speaker of the house during regular session, and who had resigned his seat in the house, was succeeded by John Wilson as speaker.
6th General Assembly
Members of the sixth General Assembly were elected August 3, 1829. The members met in regular session October 5, 1829. Charles Caldwell was elected president of the council; John Caldwell, secretary. John Wilson was speaker of the house; Daniel Ringo, clerk. The session lasted until November 21, 1829.

Sanders, secretary. John Wilson was speaker of the house; L. B. Tully, clerk. The session lasted from October 5 until November 16, 1835. The only really important Act passed during this session was the Act which provided for the election of delegates to, and the holding of, a convention for the purpose of framing a state constitution. Accordingly, the first steps were taken in the process which won Arkansas admission into the Union.
