The Seminario Regional del Sureste (known as its abbreviation SERESURE or simply the Seminary of the Southeast) was a training center for future Latin-American Catholic priests with a tendency toward Liberation Theology and ended up being the principal hotbed for this group of Catholics who sought the integration of priests into the modern world by helping the poor, the indigenous, and the dispossessed, opposing the clerical tradition of finding alliances in pre-existing circles of power.[1][2] In SERESURE, which was located in the city of Tehuacán in Puebla, Mexico, various Catholic prelates and priests were trained, not just from Mexico, but from all of Latin America.[1][3] The seminary was founded in 1969 by the initiative of several bishops toward the southeastern and pacific sections of the country, and stayed open until 1990, the year in which it was closed for good on the orders of Noberto Rivera Carrera, who considered it a Marxist institution opposed to the dogmatic teachings of the Catholic Church.[2][4]
