The township's incorporation dates to 1713 when the King of Prussia Inn, the Bird-In-Hand Inn in Gulph Mills, and later the Swedes Ford Inn were required to pay 6 shillings to the Pennsylvania legislature for licenses. The King of Prussia Inn, built in 1719, captures the historical flavor of the township. It was named in honor of Frederick the Great, but became known during the Revolutionary War as a center of food and drink. An alternate story says the Inn, first called Berry's Tavern, got its name to lure in Prussian mercenaries who spent freely.
