Дату: Титул правителей Филиппин до испанской колонизации.

Noble title in the pre Spanish Philippines
the Philippine noble title

Datu is a title which denotes the rulers (variously described in historical accounts as chiefs, sovereign princes, and monarchs) of numerous Indigenous peoples throughout the Philippine archipelago. Only a member of this birthright aristocracy (called maginoo, nobleza, maharlika, or timagua by various early chroniclers) could become a datu; members of this elite could hope to become a datu by demonstrating prowess in war or exceptional leadership. and in some cases adoption into a royal family.

Datu is the title for chiefs, sovereign princes, and monarchs throughout the Philippine archipelago. The title is still used today, especially in Mindanao, Sulu and Palawan, but it was used more extensively in early Philippine history, particularly in central and southern Luzon, the Visayas and Mindanao. Other titles still used today are lakan in Luzon, apo in central and northern Luzon, and sultan and rajah, especially in Mindanao, Sulu and Palawan. Depending upon the prestige of the sovereign royal family, the title of datu could be equated to royal princes, European dukes, marquesses and counts. In large ancient barangays, which had contacts with other Southeast Asian cultures through trade, some datus took the title of rajah or sultan. The oldest historical records mentioning datus are the 7th century Srivijayan inscriptions such as Telaga Batu to describe lesser kings or vassalized kings. The word datu is a cognate of the Malay terms dato or datuk and to the Fijian title of ratu.

In pre Islamic times, the political leadership office was vested in a rajahship in Manila and a datuship elsewhere in the Philippines.

In the later part of the 1500s, the Spaniards took possession of most of Luzon and the Visayas, converting the lowland population to Christianity from their local Indigenous religion. Although Spain eventually established footholds in northern and eastern Mindanao and the Zamboanga Peninsula, its armies failed to colonize the rest of Mindanao. This area was populated by Islamized peoples (Moros to the Spaniards) and by non Muslim Indigenous groups now known as Lumad peoples.

In the traditional structure of Moro societies, the sultans were the highest authority followed by the datus or rajah, with their rule being sanctioned by the Quran, though both titles predate the coming of Islam. These titles were assimilated into the new structure under Islam. Datus were supported by their tribes, and in return for tribute and labor, the datu provided aid in emergencies and advocacy in disputes with other communities, and warfare through the Agama and Maratabat laws.

At the beginning of the 20th century, the Lumad peoples controlled an area that now covers 17 of Mindanao's 24 provinces – but by the 1980 census, they constituted less than 6% of the population of Mindanao and Sulu. Heavy migration to Mindanao of Visayans, who have settled in the Island for centuries, spurred by government sponsored resettlement programmes, turned the Lumads into minorities. The Bukidnon province population grew from 63,470 in 1948 to 194,368 in 1960 and 414,762 in 1970, with the proportion of Indigenous Bukidnons falling from 64% to 33%, and then 14%. Datus continue to act as the community leaders in their respective tribes among a variety of indigenous peoples in Mindanao today. Moros, Lumads and Visayans now share with new settlers a homeland in Mindanao.

In more affluent and powerful territorial jurisdictions and principalities in the Visayas, such as Panay, Cebu and Leyte(which were never conquered by Spain but were accomplished as vassals using pacts, peace treaties, and reciprocal alliances), the datu class was at the top of a divinely sanctioned and stable social order in a sakop or kinadatuan (kadatuan in ancient Malay; kedaton in Javanese; and kedatuan in many parts of modern Southeast Asia), which is elsewhere commonly referred to also as a barangay. This social order was divided into three classes. The kadatuan (members of the Visayan datu class) were compared by the Boxer Codex to the titled lords (señores de titulo) in Spain. As agalon or amo (lords), the datus enjoyed an ascribed right to respect, obedience, and support from their oripun (commoner) or followers belonging to the third order. These datus had acquired rights to the same advantages from their legal Timawa or vassals (second order), who bind themselves to the datu as his seafaring warriors. The Timawa did not pay tribute or perform agricultural labor. The Boxer Codex calls them knights and hidalgos. The Spanish conquistador, Miguel de Loarca, described them as "free men, neither chiefs nor slaves". In the late 1600s, the Spanish Jesuit priest Francisco Ignatio Alcina classified them as the third rank of nobility (nobleza). These well guarded and protected highborn women were called binokot, the datus of pure descent (four generations) were called "potli nga datu" or "lubus nga datu", while a woman of noble lineage (especially the elderly) are addressed by Panay inhabitants as uray (meaning: pure as gold).

The different type of culture prevalent in Luzon gave a less stable and more complex social structure to the pre colonial Tagalog barangays of Manila, Pampanga and Laguna. The Tagalog people enjoyed a more extensive commerce than those in Visayas, having the influence of Bornean political contacts, and engaging in farming wet rice for a living. They were described by the Spanish Augustinian friar Martin de Rada as traders more than warriors. The more complex social structure of the Tagalog people was less stable during the Spaniards' arrival because it was still differentiating. In this society, the term datu, lakan, or apo refers to the chief, but the noble class (to which the datu belonged or could come from) was the maginoo class. One could be born as part of the maginoo, but could also become a datu through personal achievement.
