The act established a single office for a judge to preside over the court. Initially, the court was not within any existing judicial circuit, and appeals from the court were taken directly to the United States Supreme Court. In 1837, Congress created the United States Court of Appeals for the Seventh Circuit, placing it in Chicago, Illinois and giving it jurisdiction over the District of Illinois, . The Northern District itself was created by a statute passed on February 13, 1855, , which subdivided the District of Illinois into the Northern and the Southern Districts. The boundaries of the District and the seats of the courts were set forth in the statute: The district has since been re-organized several times. The United States District Court for the Eastern District of Illinois was created on March 3, 1905, by , by splitting counties out of the Northern and Southern Districts. It was later eliminated in a reorganization on October 2, 1978, which replaced it with a Central District, , formed primarily from parts of the Southern District, and returning some counties to the Northern District. The Northern District of Illinois, which contains the entire Chicago metropolitan area, accounts for 1,531 of the 1,828 public corruption convictions in the state between 1976 and
