When the first
Catholic missionaries, de Silva and Puellea, arrived in 1793, this region was under the ecclesiastical jurisdiction of the
Diocese of Linares. However, beginning with the first
bishop, Fray Antonio de Jesús Sacedón, all bishops had resided in
Monterrey (but the name of the diocese, after 1891 Archdiocese, was changed in Monterrey only in 1922). With the
papal bull "Ad futuram rei memoriam",
Pius IX created the
Apostolic Vicariate of Tamaulipas, on August 13, 1861, under the pastoral care of Francisco de la Concepción Ramírez. Less than a decade later on March 12, 1870,
Pius IX promulgated Papal Bull "Apostolicam in universas", thereby elevating the
Vicariate to diocese with its seat in
Ciudad Victoria. Appointed as the first bishop of Tamaulipas was Mons. Ignacio Montes de Oca y Obregón, who had been the personal chaplain to
Emperor Maximilian. In 1922, the episcopal seat was moved by Bishop Jose Guadalupe Ortiz y López from the state capital Ciudad Victoria to
Tampico, which had grown to become the largest city in the state. Tampico, located in the far southeast corner of the state, had become Tamaulipas's economic center due to its port, trade and the discovery of oil.
Diocese of Matamoros In 1958, Tamaulipas was divided into two dioceses: Matamoros and
Tampico. With the advent of extensive irrigation, prosperity and population growth came to northern Tamaulipas. On February 16, 1958,
Pius XII promulgated Papal Bull "Haud inani", creating a new diocese, extending from
San Fernando to
Nuevo Laredo, with its seat in Matamoros. The
parish church of Our Lady of Refuge became the
cathedral.
Pope John XXIII named the first bishop of the new diocese: Mons. Estanislao Alcaraz y Figueroa. Mons. Alcaraz was consecrated bishop on April 12, 1959. The diocese was renamed the
Diocese of Matamoros-Reynosa, to include a specific reference to the city of
Reynosa, in July 2024. ==Bishops==
