Illinois's at-large congressional district
former U.S. House district in Illinois
Illinois elected its United States Representative at-large on a general ticket upon achieving statehood December 3, 1818. Although the practice was first ended in 1830, it was revived several times, so that there would be at least one seat elected at large, in addition to elections in single-member districts. It last elected a US Representative at large in 1946. The district has been obsolete since.
List of members representing the district
1818–1833: one seat
From statehood to 1833, Illinois had only one congressional district, and therefore it was at-large.
1863–1873: one seat
From 1863 to 1873 there was one at-large seat in addition to the districted seats.
1893–1895: two seats
From 1893 to 1895, there were two at-large seats in addition to the districted seats.
1913–1949: two seats, then one
Two at-large seats were re-established March 4, 1913. From that date to January 3, 1943, there were two at-large seats, which was reduced to one seat from 1943 to 1949. Representation by districts also continued during this period.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Illinois's at-large congressional district”, the useful work is to connect “former U.S. House district in Illinois” to the records capable of establishing context and consequence.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Apr 20, 2026. The linked authority identifier is Q17017650. Authority coordinates are 40.000, -89.000. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1818, 1830, 1946 and 1833.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
