Due to the diverse number of Philippine languages, a program for the "development and adoption of a common national language based on the existing native dialects" was drafted in the 1935 Philippine constitution. The Commonwealth created a "Surian ng Wikang Pambansa" (National Language Institute), which was composed of Quezon and six other members from various ethnic groups. A deliberation was held, and the Tagalog (due to its extensive literary tradition) was selected as the basis for the "national language" to be called "Philipino".
