History

Will County was formed in 1836 out of Cook and Iroquois. It was named after Dr. Conrad Will, a businessman involved in salt production in southern Illinois, and also a politician.[4] Will was a member of the first Illinois Constitutional Convention and a member of the Illinois Legislature until his death in 1835. On January 12, 1836, Will County was formed from Cook County and Iroquois County. It included besides its present area, the part of Kankakee County, Illinois lying north of the Kankakee River. Will County lost that area when Kankakee County was organized in 1852, but since then its boundaries have been unchanged.

Thirty-six locations in Will County are listed on the National Register of Historic Places.

"WILL, a county in the E. N. E. part of Illinois, bordering on Indiana, has an area of 1,236 square miles (3,200 km2). It is intersected by the Kankakee and Des Plaines Rivers, branches of the Illinois. The surface is generally level, and destitute of timber, excepting small groves. The soil is very fertile, and much of it is under cultivation. The soil of the prairies is a deep, sandy loam, adapted to Indian corn and grass. In 1850 the county produced 527,903 bushels of Indian corn; 230,885 of wheat; 334,360 of oats; 32,043 tons of hay, and 319,054 pounds of butter. It contained 14 churches, 3 newspaper offices; 3472 pupils attending public schools, and 200 attending other schools. Quarries of building stone are worked near the county seat. The Des Plaines river furnishes water-power. The county is intersected by the Illinois and Michigan canal, by the Chicago branch of the Central railroad, the Chicago and Mississippi, and by the Chicago and Rock Island railroad. Named in honor of Conrad Will, for many years a member of the Illinois legislature. Capital, Joliet. Population, 16,703."
