When did the Philippine Assembly become the first elected legislative body in Southeast Asia?

The Philippine Assembly was established in 1907, becoming the first elective legislative body in Southeast Asia.1

While the Philippine-American War is often associated with the earlier struggle for sovereignty, the creation of the 80-member assembly occurred after the Philippine Commission transitioned into the upper house of a new bicameral legislature. This assembly was directly elected by a restricted electorate from single-member districts.1
