Nakaugalian, which means tradition, is the Tagalog term for Kannawidan. A celebration designed to highlight the province's diverse cultural heritage in areas such as the arts, agriculture, dance and music, cuisine, and province-based goods, or OTOP (One Town One Product). Additionally, this event was held annually to commemorate the province's formal separation from other nearby provinces, which was granted on February 2, 1818, and will mark its 200th anniversary in 2018. The entire Ilocos Sur region was getting ready for a bicentennial celebration.
Kannawidan Ylocos was first launched during the term of Deogracias Victor Savellano in 2008. It was started to promote awareness and preservation of the local culture, tradition, heritage, and customs. It was also an opportunity to showcase local products, artistry, and craftsmanship. Moreover, it was also created to boost the local tourism industry.
The main reason tourists travel to Ilocos Sur is to experience and celebrate the rich cultural heritage of the Ilocano people. The festival honors the province's founding during Spanish times and features traditional dances, food, costumes, and a lively street parade, all of which give visitors a glimpse into the distinctive history and way of life of the Ilocos people. In other words, it's a fantastic chance to fully immerse oneself in Ilocano culture.
