The roots of law, legal thought and education in Serbia go back to the 13th century. This is owed to Rastko Nemanjić, who was declared a saint under the name St. Sava. Rastko, the brother of the first Serbian king Stefan Nemanjić, was the founder of not only the ecclesiastical independence (autocephaly of the Serbian church in 1219), but he also has instituted the Serbian education, literature, health, the legal system and science.
