The prestigious National Autonomous University of Mexico (UNAM) is a public research institution located in the country of Mexico. It is renowned as one of the top universities in Latin America, with a portion of its Ciudad Universitaria campus in Mexico City being declared a UNESCO World Heritage site. This campus was designed and decorated by some of Mexico's most respected architects and painters of the 20th century, and it also hosted the main events of the 1968 Summer Olympic Games. All Mexican Nobel laureates are either alumni or faculty members of UNAM. With acceptance rates normally below 10%, the university is also known for its challenging admission process. UNAM was established in its current form on the 22nd of September, 1910, by Justo Sierra as a non-religious alternative to the Royal and Pontifical University of Mexico, which was the first Western-style university in North America, created in 1551. The university obtained autonomy from the government in 1929, allowing it to set its own curriculum and manage its own budget without any interference. This has had an immense influence on academic life at UNAM, some say leading to increased academic freedom and independence. This university was also the birthplace of the student movement of 1968.
