The federation of Stoke-on-Trent was the 1910 amalgamation of the six Potteries towns of Burslem, Tunstall, Stoke-upon-Trent, Hanley, Fenton and Longton into the single county borough of Stoke-on-Trent. An anomaly in the history of English local government, this was the first union of its type and the only such event to take place until the 1960s. The 1910 federation was the culmination of a process of urban growth and municipal change that started in the early 19th century.
