Philippine senate committee chairmanships

Philippines's 12th senatorial district, officially the Twelfth Senatorial District of the Philippine Islands (Spanish: Duodécimo Distrito Senatorial de las Islas Filipinas), was one of the twelve senatorial districts of the Philippines in existence between 1916 and 1935.

Unlike the first eleven districts which elected two members each to the Senate of the Philippines, the upper chamber of the bicameral Philippine Legislature under the Insular Government of the Philippine Islands, the two senators from this district were appointed by the Governor-General of the Philippines to serve indefinite terms in the 4th to 10th legislatures.

The district was created under the 1916 Jones Law to represent the non-Christian tribes of the northern Luzon provinces of Mountain Province and Nueva Vizcaya, the city of Baguio, and the Moro people and other non-Christian tribes of the Department of Mindanao and Sulu provinces of Agusan, Bukidnon, Cotabato,
