Mindanao is considered the major breadbasket of the Philippines, with eight of the top 10 agri-commodities exported from the Philippines coming from there. Mindanao is known as "The Philippines' Land of Promise". The name "Mindanao" is derived from the Spanish corruption of the name of the Maguindanao people, the dominant ruling ethnic group in the Sultanate of Maguindanao in southwestern Mindanao during the Spanish colonial period. The name itself means "people of the lake (Lanao)", though it is usually translated to "people of the flood plains" in modern sources. Archaeological findings on the island point to evidence of human activity dating back about ten thousand years. Around 1500 BC Austronesian people spread throughout the Philippines. The Subanon are believed to have established themselves on Mindanao Island during the Neolithic Era, or New Stone Age, the period in the development of human technology beginning around 10,000 BC according to the ASPRO chronology (between 4,500 and 2,000 BC). The evidence of old stone tools in Zamboanga del Norte may indicate a late Neolithic presence. Ceramic burial jars, both unglazed and glazed, as well as Chinese celadons, have been found in caves, together with shell bracelets, beads, and gold ornaments. Many of the ceramic objects are from the Yuan and Ming periods. Evidently, there was a long history of trade between the Subanon and the Chinese long before the latter's contact with Islam. In the classic epoch of Philippine history (900 AD onwards), the people of Mindanao were heavily exposed to Hindu and Buddhist influence and beliefs from Indonesia and Malaysia. Indianized abugida scripts such as Kawi and Baybayin was introduced via Sulawesi and Java, and the cultural icons of the sarong (known as malong or patadyong), the pudong turban, silk, and batik and ikat weaving and dyeing methods were introduced. Artifacts found from this era include the Golden kinnara, Golden Tara, and the Ganesh pendant. These cultural traits passed from Mindanao into the Visayas and Luzon, but were subsequently lost or heavily modified after the Spanish arrival in the 16th century. The Hindu-Buddhist cultural revolution was strongest in the coastal areas of the island, tending to become incorporated into local animist beliefs and customs among the tribes of the interior.
