Prior to gaining separate representation, areas now under the jurisdiction of Bukidnon were represented under the
Department of Mindanao and Sulu (1917–1935). The voters of Bukidnon were finally given the right to elect their
own representative through popular vote beginning in
1935 by virtue of Article VI, Section 1 of the 1935 Constitution. During the
Second World War, the Province of Bukidnon sent
two delegates to the
National Assembly of the Japanese-sponsored
Second Philippine Republic: one was the provincial governor (an
ex officio member), while the other was elected through a provincial assembly of
KALIBAPI members during the
Japanese occupation of the Philippines. Upon the restoration of the
Philippine Commonwealth in 1945 the province retained its pre-war
lone congressional district. Bukidnon was represented in the
Interim Batasang Pambansa as part of
Region X from 1978 to 1984, and returned
two representatives, elected at-large, to the
Regular Batasang Pambansa in
1984. Under the new Constitution which was proclaimed on February 11, 1987, the province was reapportioned into three congressional districts; each district elected its member to the restored
House of Representatives starting
that same year. The approval of Republic Act No. 10184 on September 28, 2012, increased Bukidnon's representation by reapportioning the province into four congressional districts: the municipalities of
Kalilangan and
Pangantucan were segregated from the
first district and the city of
Valencia from the
second district to form the new
fourth district. The reconfigured districts elected their respective representatives beginning in the
2013 elections. == Current Districts ==
