As the Catholic bishops during the reign of Queen Mary were dead, imprisoned or in exile, and those priests they had ordained were dying out or converting to Protestantism, William Allen conceived the idea for a seminary for English Catholic priests at Douai, where several of the chief posts were held by professors who had fled Oxford upon the reimposition of Protestantism in England. The English College at Douai was founded as a Catholic seminary in 1569. Similar colleges also came about at Douai for Scottish and Irish Catholic clergy, and also Benedictine, Franciscan and Jesuit houses. Other English seminaries for the training of priests from and for England and Wales included ones in Rome (1579), Valladolid (1589), Seville (1592) and Lisbon (1628).
