Ozamiz, officially the City of Ozamiz (Dakbayan sa Ozamiz; Lungsod ng Ozamiz), is a 3rd class component city in the province of Misamis Occidental, Philippines. According to the 2020 census, it has a population of 140,334 people. Although occasionally spelled as Ozamis in official sources like COMELEC, it is spelled as Ozamiz in Republic Act No. 321, the Ozamiz City Charter Act. In 2005, City Resolution 251-05 was passed to reiterate that it is officially spelled Ozamiz, not Ozamis. The city of Ozamiz grew out of an old Spanish town called Misamis—a name believed to have been derived from the Subanen word kuyamis, a variety of coconut. Other unverified historical sources, however, suggest that the name Misamis came from the Spanish word Misa (Catholic Mass). The old Spanish town grew in size due to the nearby Spanish garrison stationed at the stone fort named Fuerte de la Concepcion del Triunfo. The fort was constructed some time in 1756 in order to attempt to combat the pirate activities originating in the nearby Lanao area. In 1850, the town of Misamis became the capital of the District of Misamis. In October 1942, Wendell Fertig established the command headquarters of the growing guerrilla resistance to the Japanese occupation of Mindanao in the Spanish fort in the city. His headquarters was abandoned June 26, 1943, due to a large Japanese attack. Until the end of the war, the Japanese occupied this fort. During the Japanese occupation of Misamis in World War II, the "Cotta" was garrisoned by a contingent of Japanese who dug foxholes near or under the walls. This undermining of walls later led to the destruction of the southwest bastion in the earthquake of 1955. After the war, Misamis became a chartered city by virtue of Republic Act 321 on July 16, 1948. This also renamed Misamis to Ozamiz after a hero José Ozámiz who hailed from the province of Misamis Occidental and who at one time also served as its governor and congressional representative of the Lone District of Misamis Occidental, a delegate to the 1935 Constitutional Convention that resulted in the creation of the 1935 Constitution for the Philippine Commonwealth Government.
