Our history begins on January 28, 1918 ; when Societas Studiosorum Reformatorum Roterodamensis was founded by seven reformed students. SSR departments were located in every student city throughout the country, now also in Rotterdam. The association was renamed the Union, and it prospered. Over time, however, the associations in the different cities began to grow further apart. Could the Union withstand the test of time? Ties with Erasmus University In 1933 SSR-R. recognized by the Nederlandsche Handels-Hoogeschool, the predecessor of the Erasmus University Rotterdam, which means that SSR-R. from then on, he was always invited to attend official university affairs. This recognition ensured that contacts with other associations were strengthened and SSS-R. began to profile itself more outwardly. In the years leading up to World War II, SSR-R grew. as an association and, despite the threat of war, the life of a fraternity flourished. In addition, there was great concern among student associations about the growing support of the NSB among students. As a result, the associations joined forces to clarify on what grounds they rejected the NSB.
