Gonzalo Fernández de Oviedo y Valdés, commonly known as Oviedo, was a Spanish soldier, historian, writer, botanist and colonist. Oviedo participated in the Spanish colonization of the West Indies, arriving in the first few years after Christopher Columbus became the first European to arrive at the islands in 1492. Oviedo's chronicle Historia general de las Indias, published in 1535 to expand on his 1526 summary La Natural hystoria de las Indias, forms one of the few primary sources about it. Portions of the original text were widely read in the 16th century in Spanish, English, Italian and French editions, and introduced Europeans to the hammock, the pineapple, and tobacco as well as creating influential representations of the colonized peoples of the region.

Isabella I, also called Isabella the Catholic, was Queen of Castile and León from 1474 until her death in 1504. She was also Queen of Aragon from 1479 until her death as the wife of King Ferdinand II. Reigning together over a dynastically unified Spain, Isabella and Ferdinand are known as the Catholic Monarchs.
