In history, there is no proof of the foundation of Oxford University. But, the record shows that teaching in some form had begun in the university by 1096. It started developing rapidly and became popular in 1167 when Henry II restricted the entry of English students in University of Paris.
Before 1200, the Aztecs were a nomadic tribe. Hence, the foundation of Aztec civilization is dated 20 June 1325 because this is the day when the capital of Aztec Empire, Tenochtitlan, was founded. In 1521, Spanish conquistador Hernán Cortés de Monroy y Pizarro captured Tenochtitlan and brought an end to the Aztec civilization. Thus, the beginning and end of Aztec civilization were within the timeline of Oxford University.
