Malolos, officially the City of Malolos (Filipino: Lungsod ng Malolos), is a first class urban component city in the Republic of the Philippines. Malolos is considered as the 115th city in the country. It is the capital city of the province of Bulacan as the seat of the provincial government.
The city is 45 kilometres (28 mi) north of Manila, the capital city of the Philippines. It is one of the major suburbs conurbated to Metro Manila, situated in the southwestern part of Bulacan, in the Central Luzon Region (Region 3) in the island of Luzon and part of the Metro Luzon Urban Beltway Super Region. Bordering Malolos are the municipalities of Bulakan (the former capital of the province) to the southeast, Guiguinto to the east, Plaridel to the north, Calumpit to the northwest, and Paombong to the west. Malolos also lies on the north-eastern shore of Manila Bay.
Malolos was the site of the constitutional convention of 1898, known as the Malolos Convention, that led to the establishment of the First Philippine Republic, at the sanctuary of the Barasoain Church. The convent of the Malolos Cathedral served as the presidential palace at that time. Malolos gave birth to the first constitutional republic in Asia.
