when the spaniards discovered the philippines in the sixteenth century, they found the tribes along the coasts of the different islands already somewhat influenced by trade with china, siam, and the islands to the south.

under spanish rule the coast inhabitants, with the exception of the moro, soon became converts to christianity and adopted the dress of their conquerors, though they retained their several dialects and many of their former customs. then, no longer being at war with one another, they made great advances in civilization, while the hill tribes have remained isolated, retaining their old customs and beliefs.

the tales of the christianized tribes include a great mixture of old ideas and foreign influences obtained through contact with the outside world.
