Jesuit Mission in Culion started in 1906 when Culion became a leper colony under the American Commonwealth Government. It was in the mid-1980s when leprosy became curable. In 2008, the Jesuits started to focus its mission in Culion to the Indigenous Peoples called the Tagbanuas. The Tagbanuas are considered one of the oldest ethnic groups in the Philippines as they are probably descendants of the Tabon Man, the earliest human remains found in the Philippines. The Tagbanuas of Culion comprise approximately 10% of Culion's total population of more than 20,000 people.
