Puerto Rican literature is the body of literature produced by writers of Puerto Rican descent. It evolved from the art of oral storytelling. Written works by the indigenous inhabitants of Puerto Rico were originally prohibited and repressed by the Spanish colonial government. It was not until the late 19th century, with the arrival of the first printing press and the founding of the Royal Academy of Belles Letters, that Puerto Rican literature began to flourish. The first writers to express their political views in regard to Spanish colonial rule of the island were journalists. After the United States invaded Puerto Rico during the Spanish–American War and the island was ceded to the United States as a condition of the Treaty of Paris of 1898, writers and poets began to express their opposition of the new colonial rule by writing about patriotic themes. With the Puerto Rican diaspora of the early and mid-20th century, and the subsequent rise of the Nuyorican Movement, Puerto Rican literature continued to evolve and many Puerto Ricans have distinguished themselves as authors, poets, novelists, playwrights, and essayists. Early history The development of Puerto Rican literature was hampered by the Spanish colonial government, which ruled over Puerto Rico since the early 1500s. The Spanish feared that, through literature, Puerto Rico would develop its own social and cultural identity and eventually seek independence. Written works by the indigenous inhabitants were prohibited and punishable by prison or banishment. Even though the first library in Puerto Rico was established in 1642, in the Convent of San Francisco, access to its books was limited to those who belonged to the religious order. The only people who had access to the libraries and who could afford books were either appointed Spanish government officials or wealthy land owners. The poor had to resort to oral story-telling in what are traditionally known in Puerto Rico as Coplas and Decimas. The island's first writers were commissioned by the Spanish Crown to document the chronological history of the island. Among these writers were Father Diego de Torres Vargas, who wrote about the history of Puerto Rico, Father Francisco Ayerra de Santa María, who wrote poems about religious and historical themes, and Juan Ponce de León II, who was commissioned to write a general description of the West Indies. The first native-born Puerto Rican governor, Ponce de León II, wrote about Taíno culture, particularly their religious ceremonies
