The '''senatorial districts of the Philippines''' were the representations of the [[Provinces of the Philippines|provinces]] of the [[Philippines]] in the [[Philippine Senate]] from 1916 to 1935.

== History ==
{{further|Senate of the Philippines|Philippine Legislature}}
The enactment of the [[Philippine Autonomy Act]] (popularly known as "Jones Law") in August 1916 by the [[United States Congress]] provided for the creation of a [[Philippine Legislature|bicameral legislature]] consisting of a lower chamber ([[House of Representatives of the Philippines|House of Representatives]]) and an upper chamber (Senate). Until then the [[Philippine Commission]] held the executive power and some legislative powers over the American colony.

The system of government of the Philippines in its early years of transition to democratic self-government was deliberately structured to emulate the American model. The Philippines thus followed the American system of electing the members of the 24-seat [[Senate of the Philippines|senate]] by district.

The districts were organized and numbered in a roughly north–south fashion, much like the present [[Regions of the Philippines|administrative regions]]. The first eleven districts were composed of established provinces, while the twelfth was composed of the provinces of the [[Luzon]] interior and much of [[Mindanao]] – both of which were never fully administered by the old Spanish colonial government and designated by American authorities as "non-Christian" areas.

The first to eleventh districts elected two senators each by popular vote. The two senators from the twelfth district were appointed by the [[Governor General of the Philippines|U.S. governor-general]]. The setup lasted until the establishment of the [[Commonwealth of the Philippines]] in 1935, when the bicameral legislature was abolished, as the 1935 Constitution provided only for a unicameral [[National Assembly of the Philippines|National Assembly]]. However, when the Constitution was amended in 1940 to re-establish a bicameral Congress, members of the Senate had to be voted at-large, thereby effectively abolishing the district system.
