The Municipality of Imus (Filipino: Bayan ng Imus) is a first-class[1] municipality in the province of Cavite, Philippines, and it is the officially designated capital of Cavite. It has a population of 253,158 people according to the 2007 census.[2]
Because of its strategic location at the entrance to Cavite province from Metro Manila, Imus was the site of two major Katipunero victories during the Philippine Revolution against Spain. The Battle of Imus was fought on September 3, 1896 and the Battle of Alapan, on May 28, 1898, the day when the first Philippine flag was flown making Imus the "Flag capital of the Philippines". Both events are celebrated annually in the municipality. The Imus Historical Museum honors the municipality's history with lifelike scenes from the revolution.
Imus is also known as the center of religion of the Province of Cavite and home of the Imus Cathedral, the seat of the Diocese of Imus under the patronage of Nuestra Señora del Pilar. The town served as the host diocese during the 5th Asian Youth Day on November 20–27, 2009. The town is also nicknamed as the "Christmas Capital of the Philippines".
