  ## History
  
  The county forms the core of the Nemaha Half-Breed Reservation formed in the Fourth Treaty of Prairie du Chien in 1830 as land for the offspring of traders and Native Americans. The grounds of modern Indian Cave State Park mark where the county's first community, Saint Deroin, was founded in 1853 by members of the reservation as a trading post on the Missouri River. When white settlement was permitted in the Kansas–Nebraska Act of 1854, this area was part of Forney County (named for US cabinet member John W. Forney) which stretched along the Little Nemaha River from the Missouri River to west of Lincoln, Nebraska. In 1855 Nemaha County was formally founded with Brownville as its county seat. Johnson County, also founded in 1855, was initially administratively attached to Nemaha, but was organized as a stand-alone county in 1857.
  
  Brownville was the biggest city in Nebraska at the time and several firsts occurred in the county including: in 1861 the first state normal school was founded at what today is Peru State College; Daniel Freeman filed the first claim under the Homestead Act of 1862 for land on January 1, 1863, at the Brownville land office.
  
  The Nebraska State Fair was held in the county at Brownville in 1870–1871.
  
  In 1883 the county seat was moved to Auburn.
  
  In 1974 the Cooper Nuclear Station was commissioned south of Brownville.
  
  ## Geography
  
  Nemaha County lies on the eastern edge of Nebraska. Its east boundary line abuts the west boundary line of the state of Missouri (across the Missouri River). Most of the county's eastern border follows the Missouri River bordering Atchison County, Missouri. In the county's extreme northeast corner, the border follows the river's former course, lying nearly two miles (3 km) east of the present-day channel. This de facto enclave is McKissick Island. The Nemaha River flows southeastward through the upper eastern portion of the county, discharging into the Missouri River below the village of Nemaha.
  
  The county's terrain consists of low rolling hills, sloping eastward to the Missouri River valley. Much of the terrain is devoted to agriculture. The county has a total area of 410 square miles (1,100 $km^2),$ of which 407 square miles (1,050 $km^2)$ is land and 2.2 square miles (5.7 $km^2)$ (0.5%) is water.
