Manila has its origins in a herdsman's camp established by John Needham in the late 1860s. By the late 1890s, a community known as "Cinda" had developed in the area. In 1901, this community incorporated as a city, and chose the name "Manila" to honor Commodore George Dewey's 1898 victory in the Battle of Manila Bay during the Spanish–American War.
