The Department of International and European Law was established in 2006 as a result of the division of the Department of Constitutional and International Law.

The creation of the Kazan School of International Law became possible thanks to the deep historical traditions laid down in the Kazan Imperial University.

Since the formation of the Kazan Imperial University in 1804, the Department of Natural, Political Law and Law of Nations was singled out as part of its Moral and Political Branch, which included reading international law (which at that time was called law of nations).

For the first time at Kazan University, lectures on national law began to be read in 1806 by Henry Ludwig Buneman, professor of the University of Göttingen, in Latin and French.

Since 1809, classes on natural and popular law were conducted by a graduate of the University of Göttingen, the first dean of the moral and political Branch (in 1814), Johann (Ivan Arnoldovich) Finke. His pen belongs to the first guidance on jurisprudence, published in Kazan University in Russian in 1816: "Natural, private, public law and law of nations." The fourth part of Finke's work was devoted to the law of nations.

In the years 1815-1818. lectures on law of nations were read by the master of jurisprudence Е.P. Manasein. Elpidifor Petrovich Manasein was the first Russian teacher of international law in our country. In May 1818, E.P. Manasein left for the Caucasus and was soon appointed director of the colleges of the Caucasian province.

In the years 1820-1821. courses of law of nations and natural law led a prominent figure in the field of law, the dean of the moral and political branch in 1818, the rector of the Kazan Imperial University in 1819-1820, Gavriil Solntsev.
