Comenius University in Bratislava is the largest university in Slovakia, with most of its faculties located in Bratislava. It was founded in 1919, shortly after the creation of Czechoslovakia. It is named after Jan Amos Comenius, a 17th-century Czech teacher and philosopher.

John Amos Comenius was a Moravian philosopher, pedagogue and theologian who is considered the father of modern education. He served as the last bishop of the Unity of the Brethren before becoming a religious refugee and one of the earliest champions of universal education, a concept eventually set forth in his book Didactica Magna. As an educator and theologian, he led schools and advised governments across Protestant Europe through the middle of the seventeenth century.
