# St. John, Kansas

St. John is a city in and the county seat of Stafford County, Kansas, United States. As of the 2020 census, the population of the city was 1,228.

## History

The first settlement in what is today St. John was made in 1875 when William Bickerton of the Church of Jesus Christ founded a religious colony named Zion Valley. By 1879, Zion Valley had grown into a small town, and the residents renamed it St. John, after then governor John P. St. John, in order to gain favor in winning the county seat of Stafford County.
In 2015, due to diligent work of local citizens and former local graduates, the official government listing of locations has been corrected to spell the town correctly as "St. John" instead of "Saint John" that was incorrectly changed by the United States Postal Service in the 1970s.
