This module discusses the challenges of governing a stable republic in the Philippines. It explains the struggles of ethnic groups in Cordillera and Muslims in Mindanao in pushing for self-governance or autonomy. These groups sought autonomy due to reasons like defending their rights and lands, as well as having a government that respects their culture and religion. The module aims to understand the cultures, beliefs, socio-economic situations of these groups to have the right perspective on these issues still faced by the country. Recognizing the diversity in the Philippines helps promote long-term peace and unity for a stable nation.
