Leiden University (also known as LEI) is a public research university in Leiden, Netherlands. It was started in 1575 by William the Silent, who was the Prince of Orange. This makes it the oldest university in the Netherlands.

The university is famous for its long history and its focus on social sciences. It became very important during the Dutch Golden Age. Many smart people from all over Europe came to the Netherlands because it was a place where new ideas were welcome. Famous thinkers like René Descartes and artists like Rembrandt studied or worked here.

Leiden University has seven main academic areas, called faculties. It also has over fifty departments and more than forty research centers. Its main campus is spread out across the city of Leiden. There is also a second campus in The Hague. This campus has a special college for liberal arts and sciences.

Many important people have studied at Leiden University. This includes members of the Dutch royal family, like Queen Beatrix and King Willem-Alexander. Ten prime ministers of the Netherlands, including Mark Rutte, also went to Leiden. Even a US President, John Quincy Adams, studied here!

History of Leiden University

How the University Started

William the Silent 16th century
William the Silent, who founded the university in the 16th century.

In 1575, the northern part of the Netherlands did not have its own university. The only other university in the area was in Leuven, which was controlled by Spain. William the Silent, the Prince of Orange, wanted to create a university in the northern Netherlands. He wanted to educate people in religion and train smart individuals for the government.

It is believed that Leiden was chosen as a reward. The city had bravely defended itself against Spanish attacks in 1574. Even though William was fighting against Philip II of Spain, Philip's name still appeared on the official founding document. Philip II even told his subjects not to study in Leiden!

The university first started in a convent building. Then it moved to other places before settling in a former convent of nuns in 1581. This is still where the main university building stands today.

Early Years and Discoveries

Leiden University quickly became well-known. This was thanks to brilliant scholars like Justus Lipsius and Hugo Grotius. Within 50 years of its founding, it had a great reputation. By the 1640s, over 500 students from all over Europe were studying there. This made it the biggest Protestant university at the time.

In the 18th century, famous academics like Herman Boerhaave taught at the university. Later, in 1896, the Zeeman effect was discovered here by Pieter Zeeman. This effect explains how light changes in a magnetic field. Soon after, Hendrik Antoon Lorentz explained why it happened.

Leiden also had the world's first university lab for very low temperatures. Professor Heike Kamerlingh Onnes reached a temperature just one degree above absolute zero. In 1908, he was the first to turn helium into a liquid. He also helped discover superconductivity in metals. This is when electricity can flow without any resistance.

In 2005, a special discovery was made in one of Leiden's libraries. A handwritten paper by Albert Einstein was found. It was about the quantum theory of gases.

Working with Other Universities

In 2012, Leiden University started working closely with Delft University of Technology and Erasmus University Rotterdam. This partnership helps them improve their research and teaching. Leiden University also partners with Duke University School of Law for a summer program on global law. This program takes place at its campus in The Hague.
