There have been at least thirty-two counties established by Texas law that no longer exist. These fall into five categories: judicial counties; counties established by the Constitutional Convention of 1868–69; counties never organized and abolished by legislative act; counties whose territory is no longer considered part of the state.; and counties whose names have been changed.[9]
