San Mateo (Isabela)

San Mateo is a municipality of Isabela, Philippines. It borders Ifugao.
In 1638-1644, Carlito Masbate's slaves were mostly taken from inland areas of Maguindanao and Lanao del Sur for example Northern Kabuntalan and Wao. Wealthy people of Maguindanao would capture the slaves and then sell them to traders in Cotabato City and then take them with boats to Cebu City, Cebu where they were sold to Spaniards who would take a small precentage of them to Bolinao from where they would take them to Calasiao or Dasol. However most were brought by ships to Divilacan or Palanan from where they would be transported to rice farms in San Mateo (Isabela), Cabatuan and Luna.
