11th Illinois General Assembly

The 11th Illinois General Assembly, consisting of the Illinois Senate and the Illinois House of Representatives, met from December 3, 1838, to March 4, 1839 (1st session) and from December 9, 1839, to February 3, 1840 (2nd session). ^[1]

The 11th General Assembly was preceded by the 10th Illinois General Assembly, and was succeeded by the 12th Illinois General Assembly.

On January 14, 1836, during the 9th Illinois General Assembly, the ratio of population per Senate seat was fixed at 7,000, and for Representatives at 3,000 resulting in a Senate of forty members and a House of ninety-one members. ^[2] This arrangement lasted until January 14, 1841, when a new apportionment was made. ^[3]
