Zamboanga Peninsula

Zamboanga Peninsula (Cebuano: Lawis sa Zamboanga; Chavacano/Spanish: Peninsula de Zamboanga; Filipino: Tangway ng Zamboanga), designated as Region IX, is an administrative region in Mindanao, Philippines. It consists of the provinces of Sulu, Zamboanga del Norte, Zamboanga Sibugay and Zamboanga del Sur, and the cities of Isabela and Zamboanga City.

The region was previously known as Western Mindanao. Pagadian serves as the regional center, while Zamboanga City is the region's commercial and industrial center.

The name of Zamboanga is the Hispanicized spelling of the Sinama term for "mooring place" - samboangan (also spelled sambuangan; and in Subanen, sembwangan), from the root word samboang ("mooring pole"). "Samboangan" was the original name of Zamboanga City, from where the name of the peninsula is derived from. "Samboangan" is well-attested in Spanish, British, French, German, and American historical records from as far back as the 17th century.

This is commonly contested by folk etymologies which instead attribute the name of Zamboanga to the Indonesian word jambangan (claimed to mean "place of flowers", but actually means "pot" or "bowl"), usually with claims that all ethnic groups in Zamboanga were "Malays". However, this name has never been attested in any historical records prior to the 1960s.

During the ancient era, the Zamboanga peninsula was a vast territory home to various ethnic groups – the largest of which was the Subanen people. Later on, the southern coastal areas of the region were under the influence of the Javanese Majapahit Empire, although the empire never did conquer the area. The area is also believed to be the location of Sanmalan in Chinese historical records, due to the similarity of the name.

In the 14th century, the Sultanate of Sulu ruled the southwestern sections of the peninsula. By the late 15th century and early 16th century, Malay missionaries further spread Islam in the southern Philippines. Sharif Kabungsuwan, a Johore-born missionary of Malay and Arab descent established the Sultanate of Maguindanao, which the entire island of Mindanao is named after. The sultanate also occupied the entire island except present-day Caraga region, stretching from the Zamboanga Peninsula to Davao Oriental, while the Sultanate of Sulu lost its territories in Zamboanga. Maguindanao's sultans provided Mindanao fierce armed resistance against the Spanish occupation, especially under the lead of Muhammad Kudarat. They soon allied themselves with the Sulu sultanate. The Muslim natives of the region were collectively known as Moros by the Spanish, meaning "Moor", though the Iberian Moors and the Philippine Muslims had little cultural connection outside of following Islam. A large chunk of the Spanish–Moro conflict, the war between the Spanish and Mindanao's Muslim natives took place in the Zamboanga Peninsula.

In 1569, Zamboanga was chosen as the site of the Spanish settlement and garrison on La Caldera (now called Barrio Recodo). Zamboanga was one of the main strongholds in Mindanao, supporting colonizing efforts in the south of the island and making way for Christian settlements. It also served as a military outpost, protecting the island against foreign invaders and Moro pirates and their Chinese allies. The province, named and centered on Zamboanga City was partly founded by Peruvian soldiers brought by Sebastián Hurtado de Corcuera.

The Zamboanga Peninsula played a central role in the Spanish–Moro conflict. It was the site of constant battling between Spanish soldiers and Moro pirate raids. While the Spanish successfully established churches in the region, they suffered heavily at the hands of Moro raiders, and had to repeatedly withdraw from the region. While the Spanish achieved a tactical victory by launching several attacks against the Sultanate of Sulu, constant fighting and attacks persisted, giving the Moros a psychological victory.
