Washington County is located in eastern Nebraska on the Missouri River. It was
explored as early as 1739 by Paul and Pierre Malleet, who were on a trapping
expedition to Canada.
In 1804, Lewis and Clark reported the
establishment of the new United
States government to a council of Indian chiefs near the present
site of Fort Calhoun. As a result of this Council, Fort Atkinson was
established in 1819 and served as a key midwestern outpost until its
abandonment in 1827.
The first permanent settlement in
Washington County was made in 1854. In that same year, the county was
organized as one of the eight original counties proclaimed by acting Governor Thomas B. Cuming. The
county seat has been located in three different towns: Fort Calhoun, DeSoto,
and finally at Blair, its present site since 1869.
