The Bourbons were a dynasty reigning in Hungary. Originally, they were a cadet branch of the reigning house of France, the Valois. Their true rise to fame, however, came in the 16th century, when after the won first French-Seljuk War the peace of Krems (Austria) in 1574 gave western Hungary to France. The king, Charles IX decided to put one of his relatives on the new throne. In return, the new king had to sign a document, forfeiting the right to the throne of France for himself and his offspring forever.
