Document 3: Puerto Rico: Originally populated by the indigenous Taíno people, the island was claimed in 1493 by Christopher Columbus for Spain during his second voyage. Later it endured invasion attempts from the French, Dutch, and British. Four centuries of Spanish colonial government influenced the island's cultural landscapes with waves of African slaves, Canarian, and Andalusian settlers. In the Spanish Empire, Puerto Rico played a secondary, but strategic role when compared to wealthier colonies like Peru and the mainland parts of New Spain.

In 1898, following the Spanish -- American War, the United States acquired Puerto Rico under the terms of the Treaty of Paris.

Document 7: History of Puerto Rico: On August 10, 1815, the Royal Decree of Grace was issued, allowing foreigners to enter Puerto Rico (including French refugees from Hispaniola), and opening the port to trade with nations other than Spain. This was the beginning of agriculture-based economic growth, with sugar, tobacco, and coffee being the main products. The Decree also gave free land to anyone who swore their loyalty to the Spanish Crown and their allegiance to the Roman Catholic Church. Thousands of families from all regions of Spain (particularly Asturias, Catalonia, Majorca and Galicia), Germany, Corsica, Ireland, France, Portugal, the Canary Islands and other locations, escaping from harsh economic times in Europe and lured by the offer of free land, soon immigrated to Puerto Rico. However, these small gains in autonomy and rights were short lived.

Document 12: History of Puerto Rico: Located in the northeastern Caribbean, Puerto Rico formed a key part of the Spanish Empire from the early years of the exploration, conquest and colonization of the New World. The island was a major military post during many wars between Spain and other European powers for control of the region in the 16th, 17th and 18th centuries. The smallest of the Greater Antilles, Puerto Rico was a stepping - stone in the passage from Europe to Cuba, Mexico, Central America, and the northern territories of South America. Throughout most of the 19th century until the conclusion of the Spanish -- American War, Puerto Rico and Cuba were the last two Spanish colonies in the New World; they served as Spain's final outposts in a strategy to regain control of the American continents. Realizing that it was in danger of losing its two remaining Caribbean territories, the Spanish Crown revived the Royal Decree of Graces of 1815. The decree was printed in Spanish, English and French in order to attract Europeans, with the hope that the independence movements would lose their popularity and strength with the arrival of new settlers. Free land was offered to those who wanted to populate the islands on the condition that they swear their loyalty to the Spanish Crown and allegiance to the Roman Catholic Church.
