It was prominent, from the 1560s until the French Revolution, as a centre for the education of English Catholics escaping persecution in England. Connected with the University were not only the English College, Douai, founded by William Allen, but also the Irish and Scottish colleges and the Benedictine, Franciscan and Jesuit houses. Throughout Europe there were around 800 such seminaries. They prepared Jesuits for missionary work in England, with 60 migrating in the 1570s, and around 500 by 1603. The first Jesuits were Edmund Campion and Robert Parsons.
