Maynila, also known as Fort Seludong (Old Malay: Kota Seludong, Jawi script: کوتا سلودوڠ), was one of three major polities that dominated the area by the lower reaches and mouth of the Pasig River before the arrival of Spanish colonizers in the 16th century. It was a vassal polity of the Bruneian Empire. It is the site of present-day Manila, the capital of the Republic of the Philippines.
