2. The O.K. Club Popularized the Term

The Democratic president known as Martin Van Buren went up for reelection in 1940. The O.K. Club was a group based in New York that used to support Martin Van Buren. They took the club’s name from Martin Van Buren’s nickname, which was Old Kinderhook

. This came from his birth place, which was in a New York village called Kinderhook. Even though Martin Van Buren lost the election, the term β€œOK” stuck around. This may have been due to the fact that it made agreeing to documents a lot easier, as the words β€œOK” were written on a document, followed by a signature.

The Term Became a Verb in 1888
