County of yankton

History & Founding

Located in southeastern South Dakota, this county holds a rich history interwoven with the Missouri River and the early settlement of the region. Established in 1855, it was initially known as Sioux Territory before being officially designated Yankton County. The name honors the Yankton Sioux tribe, a significant indigenous group who traditionally inhabited the area. The county played a crucial role in South Dakota’s early development, serving as a temporary capital of the Dakota Territory before statehood. The first territorial legislature convened here in 1861, marking a pivotal moment in the territory's political formation. An interesting historical anecdote involves the early days of the territorial capital; due to limited resources, legislators sometimes had to share blankets to stay warm during harsh winter sessions. The county’s strategic location on the Missouri River facilitated trade and settlement, contributing significantly to the state’s westward expansion.
