Leiden University (abbreviated as LEI, Dutch: Universiteit Leiden), located in the city of Leiden, is the oldest university in the Netherlands. The university was founded in 1575 by William, Prince of Orange, leader of the Dutch Revolt in the Eighty Years' War. The Dutch Royal Family and Leiden University still have a close relationship; Queens Juliana and Beatrix and King Willem-Alexander are all former students.
Leiden University has seven faculties, over 50 departments and enjoys an outstanding international reputation. In 2013 Leiden was the highest ranked university in the Netherlands in the Times Higher Education World University Rankings, where it was rated as the 64th best university worldwide and 61st for international reputation. Shanghai Jiao Tong University's 2011 Academic Ranking of World Universities ranked Leiden University as the 65th best university worldwide. The Times Higher Education World University Rankings consistently rank Leiden University as the best university in Continental Europe for Arts and Humanities. The University is associated with ten leaders and Prime Ministers of the Netherlands including the current Prime Minister Mark Rutte, nine foreign leaders, among them the 6th President of the United States John Quincy Adams, a Secretary General of NATO, a President of the International Court of Justice and sixteen recipients of the Nobel Prize (including renowned physicists Albert Einstein and Enrico Fermi). 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 and Leiden's international reputation. During this time Leiden was home to such figures as René Descartes, Rembrandt, Hugo Grotius, Baruch Spinoza and Baron d'Holbach. The university is a member of the Coimbra Group, the Europaeum and the League of European Research Universities.
Albert Einstein was known as a professor at Leiden University. Einstein regularly taught Leiden students for a few weeks per year. His first lecture at Leiden was about "Ether and Relativity Theory".
Leiden University houses more than 40 national and international research institutes.

In 1575, the emerging Dutch Republic did not have any universities in its northern heartland. The only other university in the Habsburg Netherlands was the University of Leuven in southern Leuven, firmly under Spanish control. The scientific renaissance had begun to highlight the importance of academic study, so Prince William founded the first Dutch university in Leiden, to give the Northern Netherlands an institution that could educate its citizens for religious purposes, but also to give the country and its government educated men in other fields. It is said the choice fell on Leiden as a reward for the heroic defence of Leiden against Spanish attacks in the previous year. Ironically, the name of Philip II of Spain, William's adversary, appears on the official foundation certificate, as he was still the de jure count of Holland. Philip II replied by forbidding any subject to study in Leiden. Originally located in the convent of St Barbara, the university moved to the Faliede Bagijn Church in 1577 (now the location of the University museum) and in 1581 to the convent of the White Nuns, a site which it still occupies, though the original building was destroyed by fire in 1616.
The presence within half a century of the date of its foundation of such scholars as Justus Lipsius, Joseph Scaliger, Franciscus Gomarus, Hugo Grotius, Jacobus Arminius, Daniel Heinsius and Gerhard Johann Vossius, rapidly made Leiden university into a highly regarded institution that attracted students from across Europe in the 17th century. Renowned philosopher Baruch Spinoza was based close to Leiden during this period and interacted with numerous scholars at the university. The learning and reputation of Jacobus Gronovius, Herman Boerhaave, Tiberius Hemsterhuis and David Ruhnken, among others, enabled Leiden to maintain its reputation for excellence down to the end of the 18th century.
At the end of the nineteenth century, Leiden University again became one of Europe's leading universities. At the world’s first university low-temperature laboratory, professor Heike Kamerlingh Onnes achieved temperatures of only one degree above absolute zero of −273 degrees Celsius. In 1908 he was also the first to succeed in liquifying helium and can be credited with the discovery of the superconductivity in metals.
Kamerlingh Onnes was awarded the Nobel Prize for Physics in 1913. Three other professors received the Nobel Prize for their research performed at Universiteit Leiden: Hendrik Antoon Lorentz and Pieter Zeeman received the Nobel Prize for their pioneering work in the field of optical and electronic phenomena, and the physiologist Willem Einthoven for his invention of the string galvanometer, which among other things, enabled the development of electrocardiography.
These Nobel prize winners, but also the physicists Albert Einstein, Enrico Fermi and Paul Ehrenfest, the Arabist and Islam expert Christiaan Snouck Hurgronje, the law expert Cornelis van Vollenhoven and historian Johan Huizinga, were among those who pushed the university into a place of international prominence during the 1920s and 1930s. In 2005 the manuscript of Einstein on the quantum theory of the monatomic ideal gas (the Einstein-Bose condensation) was discovered in one of Leiden's libraries.
At present, Leiden has a firmly established international position among the top research institutes in many fields, including the natural sciences, medicine, social and behavioural sciences, law, arts and letters. Of the seventy-seven Spinozapremie (the highest scientific award of The Netherlands), nineteen were granted to professors of the Universiteit Leiden. Literary historian Frits van Oostrom was the first professor of Leiden to be granted the Spinoza award for his work on developing the NLCM centre (Dutch literature and culture in the Middle Ages) into a top research centre. Other Spinozapremie winners are linguists Frederik Kortlandt and Pieter Muysken, mathematician Hendrik Lenstra, physicists Carlo Beenakker, Jan Zaanen and Dirk Bouwmeester, astromers Ewine van Dishoeck, Martijn Franx and Alexander Tielens, transplantation biologist Els Goulmy, clinical epidemiologist Frits Rosendaal, pedagogue Rien van IJzendoorn, archeologists Wil Roebroeks and Corinne Hofman, neurologist Michel Ferrari, classicist Ineke Sluiter, social psychologist Naomi Ellemers, statistician Aad van der Vaart. Among other leading professors are Wim Blockmans, professor of Medieval History, and Willem Adelaar, professor of Amerindian Languages.
The portraits of many famous professors since the earliest days hang in the university aula, one of the most memorable places, as Niebuhr called it, in the history of science.
The University Library, which has more than 5.2 million books and fifty thousand journals, also has a number of internationally renowned special collections of western and oriental manuscripts, printed books, archives, prints, drawings, photographs, maps, and atlases. It houses the largest collections worldwide on Indonesia and the Caribbean. Scholars from all over the world visit Leiden University Library, the oldest in the Netherlands. The research activities of the Scaliger Institute focus on these special collections and concentrate particularly on the various aspects of the transmission of knowledge and ideas through texts and images from antiquity to the present day.
Among the institutions affiliated with the university are The KITLV or Royal Netherlands Institute of Southeast Asian and Caribbean Studies (founded in 1851), the observatory 1633; the natural history museum, with a very complete anatomical cabinet; the Rijksmuseum van Oudheden (National Museum of Antiquities), with specially valuable Egyptian and Indian departments; a museum of Dutch antiquities from the earliest times; and three ethnographical museums, of which the nucleus was Philipp Franz von Siebold's Japanese collections. The anatomical and pathological laboratories of the university are modern, and the museums of geology and mineralogy have been restored.
The Hortus Botanicus (botanical garden) is the oldest botanical garden in the Netherlands, and one of the oldest in the world. Plants from all over the world have been carefully cultivated here by experts for more than four centuries. The Clusius garden (a reconstruction), the 18th century Orangery with its monumental tub plants, the rare collection of historical trees hundreds of years old, the Japanese Siebold Memorial Museum symbolising the historical link between East and West, the tropical greenhouses with their world class plant collections, and the central square and Conservatory exhibiting exotic plants from South Africa and southern Europe.
Research at Leiden is well developed. There are many university research institutes and Leiden participates in over forty nationwide research schools, twelve of which being located in the heart of Leiden. In 2012 Leiden entered into a strategic alliance with Delft University of Technology and Erasmus University Rotterdam in order for the universities to increase the quality of their research and teaching. The university is also the unofficial home of the Bilderberg Group, a meeting of high-level political and economic figures from North America and Europe. In the past hundred years rare honorary degrees have been granted to figures such as Winston Churchill and Nelson Mandela.
The university has no central campus; its buildings are spread over the city. Some buildings, like the Gravensteen, are very old, while buildings like Lipsius and Gorlaeus are much more modern. The university is divided into seven major faculties which offer approximately 50 undergraduate degree programmes and over 100 graduate programmes. In recent years the university has also expanded to The Hague which is home to Leiden University College The Hague a liberal arts and sciences college and the departments of Public Administration, International Relations and Politics. It occupies a number of buildings in the historic centre of the city including a college building in Lange Voorhout.
Most of the university's departments offer their own degree programme(s). Undergraduate programmes lead to either a B.A., B.Sc. or LL.B. degree. Other degrees, such as the B.Eng. or B.F.A., are not awarded at Leiden University.
