History

Although this district was included within the confines of the Portuguese Diocese of Mylapur from the year 1606, and since 1834 formed part of the Vicariate Apostolic of Madras, next to nothing of missionary work was done here until the year 1845, when it was erected into a vicariate. The first fathers arriving at Vizagapatam found there one old priest, a Theatine, the last survivor of what was known as the Golconda mission. There was only a scattering of Catholics in a few places, mostly either European troops or camp followers. In 1850 their number was estimated at about 4000 at a time when the vicariate included the whole of the Nagpur districts in addition to those of the present diocese. These Nagpur districts were divided off and made into a diocese in 1887, when Vizagapatam also became a diocese, both suffragan to Madras.
