In Visayas, the Visayans utilized a three-class social structure consisting of the "oripun" (commoners, serfs, and slaves), the "timawa" (warrior nobility), and at the top, the "tumao" (nobility). The "tumao" consisted of blood relatives of the "datu" (community leader) untainted by slavery, servitude, or witchcraft. They were usually descendants of the children of a "datu" and secondary wives known as "sandil". Various "tumao" supporters of the "datu" are collectively referred to as "sandig sa datu" ("beside the datu"). The "tumao" were also usually employed in the court of the "datu" in various positions (though these may sometimes be filled with "timawa" as well). The chief minister or privy counselor of the "datu" was known as the "atubang sa datu" (literally "facing the "datu""). The steward who collected and recorded tributes and taxes and dispensed them among the household and dependents of the "datu" was known as the "paragahin". The "paragahin" was also responsible for organizing public feasts and communal work. The "bilanggo" was the one responsible for maintaining law and order and whose own house served as the community jail ("bilanggowan"). Both "tumao" and "timawa" were obligated to serve as the military forces of the "datu" in times of war, at their own expense.
