 One, believed to have originated from Sumatra and the Malay Peninsula, passed via the northern coast of Borneo, and through Palawan and eventually settled by the banks of the river Pasig in Luzon.These settlers soon branched into two tribes, the first became known as the "people of the river" (or 'taga-ilog'/ Tagalog), which developed a more sedentary, agricultural society built on the fertile plains fed by the Pasig and around the area of Laguna Lake; while the second hugged the shores of Manila Bay and therefore called the "people of the coast" ('ka-pampang-an'/ Pampanga), primarily engaged in fishing.Kapampangans eventually moved northwards into the interior of Luzon, and, inter-marrying with indigenous 'highlanders' and visiting Chinese traders, eventually produced the Iloko tribe.
