Tumauni is the home of the “Mangi Festival” which coincides with the patronal town fiesta in honor to St. Mathias. The festival promotes Tumauini as a source of corn and its by-products. “Mangi” is the Ibanag term for “corn” and is celebrated with street dancing along the national hi-way. One of the most enduring legacies of the Spanish colonial era lives on, quite literally in Tumauini, corn (Zea mays). It was one of the plants that came aboard the galleons and became one of the primary crops of the Philippines. It is interesting to note that corn seems to have transcended being a mere crop in Tumauini. The late National Artist for Dance, Ramon Obusan traced the origins of a traditional dance inspired by the crop to Tumauini. Thus, a corn inspired festival seemed especially appropriate for Tumauini.
