Census showed that there were 12, 542 Iranun in the Philippines. Iranuns are believed to have the same origins with the Maranaos and Maguindanaos. Since Iranun are usually mistaken as Maranaos in the northern regions in Mindanao, and as Maguindanaos in the southern, no accurate number of their population as of today is documented.
Iranun’s language is called the Iranun or Ilanun.
The fact that majority of their population resides along coastal area, Iranuns usually fish to earn a living. Others are more likely to grow crops and participate in trades since Muslims observe active trading in the island.
Small communities of Iranun observe a set of traditional and customary laws. They are governed by someone who they called the headman who acts as mediator in times of fights among his constituents, and as a facilitator during discussions and meetings within the community.
All of the Iranuns are Muslims. Since the time Christianity was introduced, resistance to accept it was already evident among the Iranuns even up to today. Christianity in Iranuns is marked with distrust that is why, even until today, no Iranun is known to be Christians. Being Muslims on the other hand, it is observed that Iranuns observe a more relaxed way of observing the five pillars of Islam. In addition to the original practices, Iranuns observe animistic religion wherein they believe that supernatural beings do not just inhabit ordinary objects but also animated ones.
