Although the extant corpus of Spanish sources isn't as detailed as Spanish accounts of chiefdoms on Hispaniola, there are tantalizing clues about the development of a possible paramount chiefdom led by Agueybana. Located on Puerto Rico's southern coast, most Spanish sources from the first half of the 16th century suggest Agueybana was the most senior of all caciques or perhaps "king" of the island. This notion is repeated by Oviedo, implied by a 1511 letter addressed to Agueybana from the Spanish monarch, and further implied by Agueybana II's leadership of the revolt against the Spanish. Indeed, Peter Martyr d'Anghiera
wrote of Puerto Rico as under the domain of one king, presumably an allusion to the powerful chiefdom of Agueybana which may have occupied a position of economic, political and ritual power. Indeed, Martyr d'Anghiera based his brief description of Puerto Rico on information from natives of Puerto Rico who traveled on a ship from Columbus's 2nd Voyage.
The cacicazgo, sometimes called Guaynia in older secondary sources, may have been near the modern town of Ponce or its environs. According to
Sued Badillo, the site of Cayabo may have been the chiefly lineage of Agueybana. Elsewhere, in a book on Agueybana, he claimed his territory stretched from the cacique Yauco to the cacique Abey. Francisco Moscoso, in his study of caciques and aldeas on the island, suggested that the land of Agueybana included the mouth of the Coayuco river and the salines of the Guanica area. This region was particularly fertile, thereby allowing for a larger yuca production. Access to abundant sources of fish further favored a demographic expansion in this area. If one remembers
Xaragua in Hispaniola, easy access to marine protein was one factor for its large population centers. Moreover, Agueybana's cacicazgo included more encomienda Indians, 600, assigned to Cristobal de Sotomayor. This encomienda included 70,000 mounds of Indian-styled conucos, suggesting the region was one of the leading centers of casabe production on the island and heavily populated. Moscoso tentatively estimated that the land of Agueybana may have included a total population of 3000 if one considers that the 600 encomienda Indians did not include the entire population but those fit for work.
Jose Oliver, drawing on archaeological evidence and early colonial sources, suggests strong ties between Puerto Rico and eastern Hispaniola. The region of Higuey appears to have participated in similar symbolism of chiefly rank and may have engaged in intermarriage or
guatiao relationships with the powerful cacicazgo on Puerto Rico's southern coast. Indeed, the name Agueybana was also used in La Saona and Cayacoa near Santo Domingo, perhaps suggestive of close relations between chiefly lineage groups in Higuey and other parts of Hispaniola with Puerto Rico. For example, there was a cacique of La Saona named Agueybana. Another cacique, in Higuey, was said to be related to the Agueybana of Puerto Rico. Further evidence can be seen in archaeological evidence of contacts across the Mona Passage that may stretch back to the 7th century in terms of cemis, stone collars and other artifacts, like duhos. It is possible that the cacicazgo later associated with Agueybana was one of these centers that engaged in relations with Hispaniola centuries before the Spanish conquest.
Unfortunately, the development of the sugar industry likely destroyed many traces of the indigenous civilization that prospered in the area. But the clues from the colonial archive and archaeological evidence point to strong ties between Puerto Rico and eastern Hispaniola. These included important symbols and paraphernalia of chiefly lineages and status. That it was Agueybana II, the brother of Agueybana I, who was able to draw 30 caciques to fight against the Spanish in 1511 points to the status of this cacique as a respected leader. In terms of "rule" over the island, it was likely based on indigenous concepts in which tribute in labor may have been acquired over vassal caciques ruling individual valleys. Close ties to Hispaniola's east may have been a further factor in the status of Agueybana's cacicazgo as it could have been a source of prestigious trade goods. Indeed, trade with the south through the Lesser Antilles to South America may have been an additional factor as guanin and other highly valued imports could have reached Puerto Rico's southern coast before being traded to other parts of the island or Hispaniola. Lastly, the fact that Agueybana II could call upon so-called "Carib" allies in his conflicts against the Spanish in the 1510s may be another indication of a regional power with influence extending to the Lesser Antilles. As succession to the position of cacique in this cacicazgo appears to have been through the maternal line, one may surmise that the exchange of women as wives from this cacicazgo to others may have been seen as a prestige for allies and subordinate caciques.
