450 years of Leiden University

Ahead of the times? We’ve been that for 450 years. As the oldest university in the Netherlands, we’ve sailed through the centuries with our sights fixed firmly on the society of the future. Our anniversary in 2025 is a chance to look back too. A chance to celebrate the impact of our research and teaching. And a chance to set our course for the next decades.

Looking ahead is in our DNA. That is what science stands for. Finding answers to questions that lead to new knowledge, solutions and innovations – and to more questions again. Because our curiosity is endless: from medical breakthroughs to better governance and from linguistic knowledge to a greener world. And this curiosity is infectious: we train generations of young people and work with community partners.

We are looking not just ahead but back too. There are wise lessons to be learned from the past 450 years: about how we work − alone and together − and about how we can do so differently. We are taking the time to reflect on academic freedom and our breadth of perspectives – things we have built on together. We are pleased to share this tradition, so join us in celebrating our 450th birthday!
