Grand Duke Ludwig insured the continued existence of the University of Freiburg in the unstable times at the beginning of the 19th century. From this point on the university has carried the names of its two benefactors in its name in gratitude to their generosity. The foundation of the Prussian Empire brought about an increase in enrollment. As a result of the influx of students from northern Germany, the university soon expanded well beyond its medieval walls. Between 1870 and 1885 enrollment increased from 200 to 1000 students, and by 1904 there were already 2000. Each of these milestones was commemorated and celebrated by the city. Today more than 21,500 students are enrolled at the Albert-Ludwig University of Freiburg. http://www.universitieshandbook.com/
