Moody County, South Dakota has a rich and diverse history that spans back to the early 19th century. The area was originally inhabited by Native American tribes, including the Dakota Sioux and Yankton Sioux.

The early years of settlement were primarily focused on agriculture, with farming and livestock becoming the main economic activities. The fertile soil and favorable climate in Moody County attracted many settlers, and the population grew steadily.

Towns such as Flandreau, which became the county seat in 1880, saw significant growth and became important centers for trade, commerce, and social activities.
