Linn county was established by an act of the legislature of the Territory of Wisconsin approved on December 21, 1837. The county was regular in shape, but four townships larger than its neighbors on the north and east, which were created at the same time. The boundaries received at this time have not been altered. The spelling of the name was Lynn, although it was spelled in the body of the act itself Linn; it took its name from Dr. Louis F. Linn, United States senator from Missouri, who was appointed to that office in 1833 and who was a friend and admirer of President Jackson, and much interested in the development of the west.
The eastern part of Linn county, perhaps one-third, had been part of the original county of Dubuque since 1834, the boundary line running from the southeast corner of the county in a northwesterly line a little to the west of the middle in the northern part of the county. Linn county then embraces within its limits two Indian land cessions. The eastern part was acquired from the Sac and Fox Indians by the treaty of September 21, 1832, known as the Black Hawk Purchase; the western part, or the other two-thirds, was acquired by treaty of October 21, 1837. The fourteen counties created by an act sub-dividing Dubuque county into new counties, which was approved October 21, 1837, were as follows: Dubuque, Clayton, Jackson, Benton, Linn, Jones, Clinton, Johnson, Scott, Delaware, Buchanan, Cedar, Fayette, and Keokuk. While most of these counties were established outright the wording of the act relating to Dubuque county implies that it was looked upon as the former county reduced in size, which was not correct, as this land from which these counties were laid out also included much of the Sac and Fox cession made after Dubuque county had been formed and laid out, and which county had not been ceded to the United States government.
These boundary lines were reduced in size later; however the boundaries of Dubuque, Delaware, Jackson, Jones, Linn, Clinton, Cedar, and Scott have remained as they were laid out at the time. The Territory of Iowa was created by an act of congress approved June 12, 1838.
Among the bills passed by the first legislature, which met during the winter of 1838 and 1839, was the following: "An Act to Organize the County of Linn, and establish the Seat of Justice thereof.
"Section 1. Be it enacted by the Council and House of Representatives of the Territory of Iowa, that the county of Linn be and the same is hereby organized from and after the 10th of June next, and the inhabitants of said county be entitled to all the rights and privileges to which, by law, the inhabitants of other organized counties of this Territory are entitled, and the said county shall be a part of the Third Judicial District, and the District Court shall be held at the seat of justice of said county, or such other place as may be provided until the seat of justice is established.
