The Diocese of Pagadian comprises the City of Pagadian and 21 municipalities in the northern and eastern parts of Zamboanga del Sur. It was created on November 2, 1971. It is a suffragan of the Archdiocese of Ozamiz, and its titular patron is the Santo Niño. Like many other large provinces in the Philippines, the Zamboangas were just one province way back in the Spanish era. As the population increased over the years, the large provinces had to be split up into two or three separate provinces for easier administration. After World War II, the movement of people into the old province of Zamboanga was so great and so fast that it had to be divided into Zamboanga del Norte and Zamboanga del Sur in 1952. Dipolog is the capital city of Zamboanga del Norte while Pagadian is the capital of Zamboanga del Sur.
