Early Pottawattamie Area Residents
Before the Pottawattamie area was opened for general settlement in 1853, it temporarily housed two groups:
  • As a consequence of the 1833 Chicago Treaty, The Prairie Potawatomi bands of Native Americans, (with some Ojibawa and Ottawa) left the greater Chicago area beginning in 1835, briefly stopped in the Platte area of northwest Missouri, and came north to southwest Iowa in 1837 and 1838.
  • Faced with increasing hostility from the general population, most Latter Day Saints Church members (known familiarly as Mormons) abandoned the Nauvoo, Illinois area in early 1846 and began crossing southern Iowa. While preparing for the arduous journey to Utah, they lived in the Pottawattamie area. (Initially many stayed in Winter Quarters, now Florence, Nebraska.)

  • The Prairie Potawatomi to their new reservation in Kansas near Topeka. Most were gone by the end of 1848.
  • The Mormons across the plains and over the mountains to the Salt Lake area. The last company of Pottawattamie area Mormons left for Utah in the Spring of 1853.
