Problem: Sepultura (Portuguese pronunciation: [se.puw.'tu.ra], "grave") is a Brazilian heavy metal band from Belo Horizonte, Brazil. Formed in 1984 by brothers Max and Igor Cavalera, the band was a major force in the thrash metal and groove metal genres during the late 1980s and early 1990s, with their later experiments drawing influence from alternative metal, world music, nu metal, hardcore punk and industrial metal. Sepultura has had several changes in its lineup since its formation, with Max and Igor Cavalera departing in 1996 and 2006, respectively. Sepultura's current lineup consists of vocalist Derrick Green, guitarist Andreas Kisser, bassist Paulo Jr. and drummer Eloy Casagrande.

Sepultura was formed in 1984 in Belo Horizonte, the capital city of Minas Gerais, Brazil. The band was founded by teen brothers Max and Igor Cavalera, the impoverished sons of Vania, a model, and Graciliano, a well-to-do Italian diplomat whose fatal heart attack left his family in financial ruin. Graciliano's death deeply affected his sons, inspiring them to form a band after Max heard the album Black Sabbath Vol. 4 the very same day. They chose the band name Sepultura, the Portuguese word for "grave", when Max translated the lyrics of the Motorhead song "Dancing on Your Grave".  The brothers' early influences included Led Zeppelin, Black Sabbath and Deep Purple, and metal and hard rock artists of the early 1980s, such as Van Halen, Iron Maiden, Motorhead, AC/DC, Judas Priest, Ozzy Osbourne and V8. They would travel to a record shop in Sao Paulo that mixed tapes of the latest records by American bands. Their listening habits changed dramatically after being introduced to Venom. As Igor Cavalera put it:  The Cavalera brothers started listening to bands such as Hellhammer, Celtic Frost, Kreator, Sodom, Megadeth, Exodus and Exciter. They also had influences on Brazilian metal from bands like Stress, Sagrado Inferno and Dorsal Atlantica. By 1984, they had dropped out of school. After several early membership changes, Sepultura established a stable lineup of Max on guitar, Igor on drums, vocalist Wagner Lamounier, and bassist Paulo Jr. Lamounier departed in March 1985 after disagreements with the band, and moved on to become the leader of the pioneering Brazilian black metal band Sarcofago. After his departure, Max took over the vocal duties. Jairo Guedes was invited to join the band as lead guitarist.

Question:
The Principalia or noble class was the ruling and usually educated upper class in the pueblos of the Spanish Philippines, comprising the gobernadorcillo (who had functions similar to a town mayor), and the cabezas de barangay (heads of the barangays) who governed the districts. The distinction or status of being part of the principalia was a hereditary right. However, it could also be acquired, as attested by the royal decree of 20 December 1863 (signed in the name of Queen Isabella II by the Minister of the Colonies, Jose de la Concha). This distinguished upper class was exempted from tribute (tax) to the Spanish crown during the colonial period.
From the beginning of the colonial period in the Philippine, the Spanish government built on the traditional pre-conquest socio-political organization of the barangay and co-opted the traditional indigenous princes and their nobles, thereby ruling indirectly. The barangays in some coastal places in Panay, Manila, Cebu, Jolo, and Butuan, with cosmopolitan cultures and trade relations with other countries in Asia, were already established principalities (Kinadatuan) before the coming of the Spaniards. In other regions, even though the majority of these barangays were not large settlements, yet they had organized societies dominated by the same type of recognized aristocracy and lordships (with birthright claim to allegiance from followers), as those found in more established, richer and more developed principalities. The aristocratic group in these pre-colonial societies was called the datu class. Its members were presumably the descendants of the first settlers on the land or, in the case of later arrivals, of those who were datus at the time of migration or conquest.  The duty of the datus was to rule and govern their subjects and followers, and to assist them in their interests and necessities. What the chiefs received from their followers was: to be held by them in great veneration and respect; and they were served in their wars and voyages, and in their tilling, sowing, fishing, and the building of their houses. The natives attended to these duties very promptly, whenever summoned by their chief. They also paid their chief tribute (which they called buwis) in varying quantities, in the crops that they gathered. The descendants of such chiefs, and their relatives, even though they did not inherit the Lordship, were held in the same respect and consideration, and were all regarded as nobles and as persons exempt from the services rendered by the others, or the plebeians (timawas). The same right of nobility and chieftainship was preserved for the women, just as for the men.  Some of these principalities and lordships have remained, even until the present, in unHispanicized  and mostly Lumad and Muslim parts of the Philippines, in some regions of Mindanao.
