Meriwether Lewis and William Clark (Lewis & Clark Expedition) spent time near the
Missouri River in Iowa in
1804. Explorer Zebulon Pike raised the first American flag in Iowa on the southern edge of
current Burlington in
1805. Fort Madison was built by a US Army detachment from St. Louis in 1808; abandoned and

1860 was 674,913. By 1870, there were 1,194,020 Iowans.
