[1] With the bull Ad Christi Nomen, Pope Pius XI bifurcated the Archdiocese of Verapoly and erected the Diocese of Vijayapuram on 14 July 1930.

The first phase of the migration started in the middle of the 18th century when Latin Catholics from the Diocese of Cochin came to Vaisiambhagom, Nedumudy, Kanjpadam and its vicinities.

The second phase began at the first half of the 19th century, when people from different parishes of Quilon reached Maramon, Ranny, Vanavathukkara, Thiruvalla, Changanacherry and Poovam.

The arrival of Brother Rockey Palackal, OCD, at the end of the 19th century geared upon the fourth phase of the history of the Diocese of Vijayapuram.

Brother Rockey, as a zealous father, worked hard in Kottayam, Thellakom, Chengalam and Kumarakom and preached the Good News to the native people.
