Document 13: Spanish West Indies: The islands that later became the Spanish West Indies were the focus of the voyages of the Spanish expedition of Christopher Columbus in America. Largely due to the familiarity that Spaniards gained from Columbus's voyages, the islands were also the first lands to be permanently colonized by Spanish in the Americas. The Spanish West Indies were also the most enduring part of Spain's American Empire, only being surrendered in 1898 at the end of the Spanish–American War. For over three centuries, Spain controlled a network of ports in the Caribbean including Havana (Cuba), San Juan (Puerto Rico), Cartagena de Indias (Colombia), Veracruz (Mexico), and Portobelo, Panama, which were connected by galleon routes.
Document 14: 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. After the fall of Napoleon, absolute power returned to Spain, which revoked the Cádiz Constitution and reinstated Puerto Rico to its former condition as a colony, subject to the unrestricted power of the Spanish monarch.
Document 15: 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.
