The black “root” has been systematically “uprooted” from the main “trunk” of the Puerto Rican nation.Jorge DuanyScholars who study Puerto Rico's past have struggled with the question of how to define the island’s national identity. Is the essence of Puerto Rican identity rooted in Spain, does it have its origins in Africa, in the legacy of the native Tainos, or is it a product of two or all three of these? This polemical question has yet to be resolved and remains a subject of much debate. The island's black past is often overlooked, and what has been written tends to focus on the enslaved labor force and its ties to the nineteenth-century plantation economy. Few works are specifically devoted to the study of the island's seventeenth- and eighteenth-century Afro-Puerto Rican population. Recent scholarship has begun to address this oversight. For example, the efforts of fugitive slaves and free black West Indian migrants making their way to Puerto Rico have been well documented. Yet, little is known about the number or identity of these runaways. How many slaves made their way to freedom in Puerto Rico, who were they, and where did they come from? Perhaps more importantly, what about their new lives on the island? How were they able to create a sense of belonging, both as individuals and as part of a community within the island's existing population and society? What follows strives to answer these questions by taking a closer look first at the number and identity of these fugitives, and second at how new arrivals were assimilated into their new surroundings through marriage and family formation while their integration was facilitated by participation in the local economy. Through their religious and civic activity Afro-Puerto Ricans were able to create a niche for themselves in San Juan and eventually a community of their own in Cangrejos. In doing so, they helped shape the island's national identity.
