The Archdiocese of Puebla de los Angeles, Puebla (Latin: Archidioecesis Angelorum) is the oldest Roman Catholic diocese in Mexico. It was established on October 13, 1525 as the diocese of Tlaxcala and retained that name until it was elevated to an archdiocese in 1903. In 1959 a new Diocese of Tlaxcala was created and is suffragan to the Archdiocese of Puebla de los Angeles, Puebla.
A separate diocese for Mexico City was created in 1530 and replaced Seville, Spain as Tlaxcala's metropolitan in 1546, so its place as Mexico's most important Catholic see was short-lived, but Puebla de los Angeles, Puebla is one of the largest archdioceses in Mexico today....Wikipedia (
