The story

How Hayti came to be

From Wikipedia’s history of Hayti.

Read it all →

Hayti was platted in 1907 when the South Dakota Central Railway was built through the area. The town won an election to become the county seat in 1910, taking the title from Castlewood; however, Castlewood sued to keep the county seat and won the case. In 1914, a second election gave Hayti the county seat for good.
