During the past two decades, many of the traditional conceptions about the configuration of the cultural landscape of precolonial Puerto Rico have been critically addressed from both political and disciplinary perspectives. Colonialist undercurrents embedded in the traditional models used to structure the indigenous history of the island have come into question and some of the fundamental ideas about the social and cultural makeup of the human collectivities that inhabited Puerto Rico have been drastically altered. The timing of the initial occupation of the island has been pushed back to more than five thousand years ago and the potential origin of some of these societies has also been reconsidered, including the possibility that some of groups moved across the Caribbean Sea from the Isthmo-Colombian region from where they brought phytocultural traditions that included the cultivation of a wide array of important economic plants. The cultural landscape of the island later expanded with the arrival of migrants from the surrounding continents who participated in long-distance interaction networks, as demonstrated by the trade of exotic goods mainly used for making personal adornments. The cultural plurality that existed on the island led to the development of distinct traditions that were not only forged by the diverse interactions that took place within Puerto Rico, but also by engagements that continued to take place with the inhabitants of other islands of the Antilles and surrounding continental regions. This all led to the articulation of a mosaic of cultural traditions that were diffusely united through the intersocietal negotiation of a set of codes that allowed the different collectivities to engage with one another while retaining their differences.
