13th Illinois General Assembly
The 13th Illinois General Assembly, consisting of the Illinois Senate and the Illinois House of Representatives, met from December 5, 1842, to March 6, 1843.
The 13th General Assembly was preceded by the 12th Illinois General Assembly, and was succeeded by the 14th Illinois General Assembly.
On January 14, 1841, during the 12th Illinois General Assembly, the ratio of population per Senate seat was fixed at 12,000, and for Representatives at 4,000 resulting in a Senate of forty-one members and a House of one hundred twenty-one members. This arrangement lasted until February 25, 1847, when a new apportionment was made.
Senate
The reapportionment of the Senate created problems as itmade no accounting for the sixteen senators whose terms did not expire creating a number of disputes. Holdover senators combined with newly elected senators led to 4 senators in districts where the new apportionment had only allocated 3 senators. As the situation was deemed too difficult to solve and was not challenged, the Senate retained all 4 senators and the Senate had 42 members for the length of the term.
| Seats in District | Counties represented | Image | Senator | Remarks |
| 1 | Sangamon | Disputed. Baker was the holdover senator with two years remaining on his term. His district had been reduced from 4 counties to just Sangamon. Harrison won election as Senator in the new district. The issue was referred to the Select Committee for resolution and it was decided that it would be unfair to have two senators representing Sangamon county and Harrison was excluded. No one contested the decision. | ||
