In 1762, during a time of rising social tensions, France formally expelled the Jesuits from the country. This resulted in the college's decline and eventual end. The expulsion split the college. The Jesuit masters and many of the students fled to the
Austrian Netherlands, now part of modern
Belgium, moving first to
Bruges, and then to Liège, where the college operated under the protection of the
Prince-Bishop of Liège from 1773. King
Louis XV continued the college at St Omer, under the direction of secular clergy. When the Jesuit order was suppressed everywhere in 1773, the dual system ended, but the college never regained its prominence. In 1793, the
French Revolution weakened the college at Saint Omer, and France's
declaration of war on
Great Britain finally ended it. The English masters and students were interned until February 1795. Meanwhile, the English penal laws and resulting discrimination had changed, and Roman Catholic education was now possible in England. Once released in France, some of the staff and most of the hundred remaining students went to England, to avoid the war on the European continent. A former member,
Thomas Weld, donated a mansion and grounds at Stonyhurst, in
Lancashire. The modern
Stonyhurst College continues to this day as a direct lineal descendant of the college of
Saint-Omer. In France, the
Lycée Alexandre Ribot was developed on the site of the former Jesuit college in Saint Omer.
Heythrop College, University of London, the now-defunct specialist Philosophy and Theology constituent College of the
University of London, shared its (1614) foundation in Liège with Stonyhurst College. ==Notable alumni==
