Maguindanao's at-large congressional district was a short-lived congressional district that encompassed the formerly undivided province of Maguindanao in the Philippines. It was represented in the Batasang Pambansa from 1984 to 1986.[1] Maguindanao was created by the further division of Cotabato into three provinces in 1973 out of thirteen ethnic Maguindanao-dominated municipalities of the former province.[2] Due to the absence of a legislature since the 1972 imposition of martial law, no electoral district was formed in the new province under its charter. When a national parliament known as the Batasang Pambansa was convened in 1978, Maguindanao and four other provinces in Central Mindanao were collectively represented by eight delegates who were elected across Region XII. The only time a provincewide at-large district was used to elect representatives for Maguindanao was during the 1984 Philippine parliamentary election for two seats in the Regular Batasang Pambansa shared with the chartered city of Cotabato.[3]
