Religion Prior to colonization, the region had a complex religious system which involved various deities. Among these deities include: • Gugurang, the supreme god who dwells inside of
Mount Mayon where he guards and protects the sacred fire in which Asuang, his brother was trying to steal. Whenever people disobey his orders or commit numerous sins, he would cause Mount Mayon to burst lava as a sign of warning for people to mend their crooked ways. Ancient Bikolanos had a rite performed for him called Atang. • Asuang, the evil god who always tries to steal the sacred fire of Mount Mayón from his brother, Gugurang. Addressed sometimes as
Aswang, he dwells mainly inside Mount Malinao. As an evil god, he would cause the people to suffer misfortunes and commit sins. • Bulan, the god of the pale moon, he is depicted as a pubescent boy with uncommon comeliness that made savage beast and the vicious mermaids (Magindara) tame. He has deep affection towards the sea god Magindang, but plays with him by running away so that Magindang would never catch him. The reason for this is because he is shy to the man that he loves. If Magindang manages to catch Bulan, Haliya always comes to free him from Magindang's grip. • Magindang, the god of the sea and all its creatures. He has deep affection to the lunar god Bulan and pursues him despite never catching him. Due to this, the Bicolanos reasoned that it is to why the waves rise to reach the Moon when seen from the distant horizon. Whenever he does catch up to Bulan, Haliya comes to rescue Bulan and free him immediately. •
Bakunawa, a gigantic sea serpent deity who is often considered as the cause of eclipses, the devourer of the Sun and the Moon, and an adversary of Haliya as Bakunawa's main aim is to swallow Bulan, who Haliya swore to protect for all of eternity. • Okot, god of forest and hunting.

UNESCO released its 3rd world volume of
Endangered Languages in the World, where 3 critically endangered languages were in the Philippines. One of these languages in the
Isarog Agta language which has an estimated 5 speakers in the year 2000. The language was classified as
Critically Endangered, meaning the youngest speakers are grandparents and older, and they speak the language partially and infrequently and hardly pass the language to their children and grandchildren anymore. If the remaining 150 people do not pass their native language to the next generation of
Isarog Agta people, their indigenous language will be extinct within a period of 1 to 2 decades. The Isarog Agta people live within the circumference of Mount Isarog, though only 5 of them still know their indigenous language. They are one of the original Negrito settlers in the entire Philippines. They belong to the
Aeta people classification, but have distinct language and belief systems unique to their own culture and heritage.

Nabua (Which formerly included present day Balatan), Libmanan (Then included present day Cabusao and some barangays of Canaman Pamplona and Pasacao), Sipocot, Pili, Calabanga, Iriga then followed Nueva Caceres with some barangays being classified as urban. By the late 1990s the remaining rural municipalities were Siruma, Garchitorena, Presentacion and Cabusao. Until 2007 when all of these 4 municipalities were classified as urban by the National Statistics Office. ==Economy==
