 Most of Provence remained strongly Catholic, with only one enclave of Protestants, the principality of Orange, Vaucluse, an enclave ruled by Prince William of the House of Orange-Nassau of the Netherlands, which was created in 1544 and was not incorporated into France until 1673.An army of the Catholic League laid siege to the Protestant city of Mėnerbes in the Vaucluse between 1573 and 1578.The wars did not stop until the end of the 16th century, with the consolidation of power in Provence by the House of Bourbon kings.
