Leiden University (abbreviated as LEI; Dutch: Universiteit Leiden) is a public research university in Leiden, Netherlands. It was founded as a Protestant university in 1575 by William, Prince of Orange, making it the oldest institution of higher education in the Netherlands. Known for its historic foundations and emphasis on the social sciences, the university came into particular prominence during the Dutch Golden Age, when scholars from around Europe were attracted to the Dutch Republic due to its climate of intellectual tolerance. During this time, Leiden became the home to individuals such as René Descartes, Rembrandt, Christiaan Huygens, Hugo Grotius, Baruch Spinoza, and Baron d'Holbach. The university has seven academic faculties and over fifty subject departments, housing more than forty national and international research institutes. Its historical primary campus consists of buildings in multiple places in the college town of Leiden, while a second campus located in The Hague houses a liberal arts college (Leiden University College The Hague) and several of its faculties. It is a member of the Coimbra Group, the Europaeum, and a founding member of the League of European Research Universities. The university has produced twenty-six Spinoza Prize Laureates and sixteen Nobel Laureates. Members of the Dutch royal family such as Queen Juliana, Queen Beatrix, and King Willem-Alexander are alumni, and ten prime ministers of the Netherlands including incumbent Mark Rutte. US President John Quincy Adams also studied at the university. Source: Wikipedia (en)
