In 1787, the fledgling United States defined theNorthwest Territory, which included the area of present-day Indiana. In 1800, Congress separatedOhio from the Northwest Territory, designating the rest of the land as theIndiana Territory.[3] PresidentThomas Jefferson choseWilliam Henry Harrison as the territory's first governor, andVincennes was established as the territorial capital.[4] After theMichigan Territory was separated and theIllinois Territory was formed, Indiana was reduced to its current size and geography.[3] By December 1816 the Indiana Territory was admitted to the Union as a state.
Starting in 1794, Native American titles to Indiana lands were extinguished by usurpation, purchase, or war and treaty. The United States acquired land from theNative Americans in the1809 treaty of Fort Wayne, and by thetreaty of St. Mary's in 1818 considerably more territory became property of the government. This included the future Boone County, designating areas covered by the Delaware New Purchase.
Boone County was created by the state legislature on April 1, 1830, withJamestown (which had been first settled that year) named as the initial county seat. The county was named for frontiersmanDaniel Boone.[5] The interim county commissioners met on May 1 of the following year to identify a permanent seat of government, which by law had to be within 2 miles (3.2 km) of the county's center; the [future] city ofLebanon was selected to serve this purpose.[6]

It contains about 418.5 square miles (108,500 hectares), two-thirds of which is in cultivation. Its central position, excellent soil, and available water power have been in its favor.[7] The highest point of the county (984 feet (300 meters) ASL) is a small hill two miles/3.2 km northeast ofLebanon.[8]The upper part of the county is drained by Sugar Creek, flowing westward intoMontgomery County; the southwest part of the county is drained by Big Raccoon Creek, also flowing west-southwestward into Montgomery. The southeast part of the county is drained by Eagle Creek and its tributaries, flowing southward intoMarion County.[9]
