Warren County was created on March 1, 1827 and was formed from Wabash New Purchase and Unorganized Land. The Wabash New Purchase: Begun in 1820, this tract lasted until 1835 and then became all of White County and portions of the counties of Boone, Carroll, Fountain, Hendricks, Jasper, Montgomery, Morgan, Parke, Putnam, Tippecanoe, Vermillion, and Warsaw. The County was named for Dr. Joseph Warren, killed at the Battle of Bunker Hill, in which he fought as a private, because his commission as a General had not yet taken effect.
The County Seat is Williamsport. Williamsport wasn't always the County Seat. The first seat of justice of Warren County was located at Warrentown, two miles up the river from Williamsport. For reasons unknown, this site proved unsatisfactory and the Legislature on January 22, 1829, passed an act for the relocation of the County Seat. On the second Monday of June 1830, locating commissioners met at Warrentown, and after a liberal donation of land by William Harrison, selected the present site of Williamsport for the new County Seat. First settled in 1829 by Wm. Harrison, J. J. McAlilly, James H. Buell and Thomas Gilbert, by 1849 Williamsport contained 100 houses and 400 inhabitants.
Counties adjacent to Warren County are Benton County (north), Tippecanoe County (east), Fountain County, Vermillion County (south), Vermilion County, Illinois (west).
