Amidst continuous population migration to the area of kabasalan, particularly to the site of the Goodyear Rubber Corporation (known as the peoples place of work), Gregorio Cainglet, the first elected Alcalde of Naga transferred the seat of government of kabasalan in 1936. The year 1965 was a memorable year for Naga as it was created as Municipality by virtue of Executive Order 97 issued by President Diosdado Macapagal.
