Calumpit

Calumpit  is a 1st class municipality in the province of Bulacan, Philippines.

Calumpit was already an established barangay under the leadership of Gat Maitim prior to the Fall of the Kingdom of Tondo in June 1571. Other nearby villages were Gatbuka, Meyto, Meysulao, Pandukot, Malolos, Macabebe, Hagonoy, and Apalit. When Calumpit was hispanised and established as a political and geographical entity in 1572, they chose what is today Barangay Población as the site of the church and the administrative center of the aforementioned villages, which were annexed to it.
