Roman Catholic Archdiocese of Calcutta

The Roman Catholic Metropolitan Archdiocese of Calcutta (Archidioecesis Calcuttensis) is an ecclesiastical Latin Church territory of the Catholic Church in India.

History
The archdiocese was originally erected as the Apostolic Vicariate of Bengal in 1834 by Pope Gregory XVI, and renamed as the Apostolic Vicariate of Western Bengal in 1850 by Gregory's successor, Pope Pius IX.

On 1 September 1886, when the Catholic hierarchy was created in British India by Pope Leo XIII, the vicariate was elevated to the rank of metropolitan archdiocese and renamed as the "Archdiocese of Calcutta".

Over the course of times the archdiocese was frequently divided and new metropolitan provinces were created: Ranchi, Guwahati and Patna. , the metropolitan province of Calcutta covers the state of West Bengal. The suffragan sees are: Asansol, Bagdogra, Baruipur, Darjeeling, Jalpaiguri, Krishnagar and Raiganj.

The archdiocese's cathedral, the seat of its archbishop, is the Cathedral of the Most Holy Rosary, commonly called the "Portuguese Church". Calcutta also houses the oldest Catholic church in the area, the Basilica of the Holy Rosary, in Bandel - a former Portuguese settlement - some 40 kilometers (25 miles) north of the city of Kolkata.

The current archbishop of Calcutta is Thomas D'Souza, having been appointed by Pope Benedict XVI on 23 February 2012.
