History
Clark County lies on the north bank of the Ohio River. A significant gateway to the state of Indiana, Clark County's settlement began in 1783. The state of Virginia rewarded General George Rogers Clark and his regiment for their victorious capture of Forts Kaskaskia, Cahokia, and Vincennes from the British, by granting them 150,000 acres (610 km2) of land. A small portion of this land, 1,000 acres (4.0 km2), became known as Clarksville, the first authorized American settlement in the Northwest Territory, founded the next year in 1784.
Clark County was formed on February 3, 1801, with territory annexed from Knox, the first county formed in the Territory in 1790. This original area in Clark County was subsequently altered and reduced with the formation of other counties: Harrison (1808), Franklin, Jefferson, and Wayne (1811), Switzerland and Washington (1814), Jackson and Ripley (1816), Jennings (1817), Crawford and Randolph (1818), Fayette and Floyd (1819), Scott (1820), Union (1821), Decatur and Rush (1822).
This brief starts where responsible research should: with the source description of “Clark County, Indiana” as county in Indiana, United States. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as county in Indiana, United States. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Sep 16, 2026. The linked authority identifier is Q504441. VIAF identifies the subject as 133677975. The Library of Congress control number is n79064853. Authority coordinates are 38.480, -85.720. 5 of 5 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2020, 1783, 1784 and 1801.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
