Spanish jurists, led by Juan López de Palacios Rubios and the Council of the Indies, drafted the Requerimiento to be read to Indigenous peoples before conquest, asserting Spain’s claim by divine and papal authority, demanding submission to Spanish rule and Christianity, and warning of war or enslavement; often read perfunctorily, it revealed the gap between law and colonial practice.

Issued by Ferdinand II of Aragon and Juana of Castile at Valladolid; a revision and expansion of the 1512 Laws of Burgos refining regulations on Indigenous labor, settlement organization, and religious instruction in the Americas, reinforcing royal oversight while attempting to address abuses within the encomienda system.

A political treatise offering pragmatic advice to rulers on how to gain and maintain power. It was dedicated to Lorenzo de’ Medici, intended as both a plea for political employment and a manual for effective rule. Machiavelli argued that leaders should prioritize stability and authority, even through deception, fear, or cruelty when necessary, famously noting it is better for a prince to be feared than loved if he cannot be both.

On September 25, 1513, Vasco Núñez de Balboa crossed the Isthmus of Panama and became the first recorded European to sight the Pacific Ocean from the Americas. He formally claimed the vast body of water—then called the “South Sea” (Mar del Sur)—for the Crown of Spain, establishing Spain’s strategic awareness of a western ocean that would shape future exploration and imperial expansion. These events were recorded in a letter he wrote as a report to Spain.

Hernán Cortés reported to King Charles I of Spain (Charles V) on his march into the Aztec Empire, the seizure of Tenochtitlan, and the complex alliances he forged with Indigenous rivals of the Mexica. The letter justified his unauthorized actions by portraying the conquest as both a service to the Crown and a campaign to expand Christian rule and Spanish sovereignty in the newly claimed territories.

Giovanni da Verrazzano’s first voyage was undertaken in the service of King Francis I of France to find a western sea route to Asia. Sailing along the Atlantic coast of North America Verrazzano made some of the earliest European descriptions of the region, including New York Harbor. His voyage strengthened France’s claims to North America and laid the groundwork for later French exploration and colonization.

King Charles I of Spain (Emperor Charles V) tried to reform colonial administration and curb abuses against Indigenous peoples in Spanish America. The laws sought to end Indigenous enslavement, restrict the power of encomenderos, and protect native communities following advocacy from reformers such as Bartolomé de Las Casas. Although intended as a major humanitarian reform, enforcement sparked resistance among colonists—especially in Peru—demonstrating the limits of royal authority in the early Spanish Empire.

A passionate denunciation of Spanish colonial abuses against Indigenous peoples in the Americas. Drawing on his experiences as a former encomendero turned Dominican friar, Las Casas described acts of violence, exploitation, and depopulation to persuade King Charles I of Spain (Charles V) to strengthen reforms and enforcement of earlier protective legislation. The work became highly influential in shaping European debates over empire, Indigenous rights, and Spanish colonial policy.

A vast ethnographic study of Aztec society, religion, language, and daily life based on testimony from Indigenous Nahua informants in central Mexico. Often known as the Florentine Codex, the manuscript preserves one of the most detailed contemporary records of pre-conquest and early colonial New Spain, blending Nahuatl and Spanish text with hundreds of illustrations.

Elizabeth I granted letters patent to Sir Humphrey Gilbert, authorizing him to discover, claim, and govern remote “heathen and barbarous lands” not already possessed by any Christian prince in the name of England. The patent empowered Gilbert to establish colonies, exercise civil and criminal jurisdiction over settlers, and retain a share of profits, laying early legal foundations for English overseas expansion.

Elizabeth I granted a charter to Sir Walter Raleigh, authorizing him to discover, occupy, and govern remote lands not already claimed by a Christian prince, shortly after the death of his half-brother Sir Humphrey Gilbert in 1583. The charter empowered Raleigh to establish colonies and exercise civil authority over settlers, laying the legal groundwork for England’s first sustained attempts at colonization in North America.

Issued by James I of England to address poverty and social unrest in England while supporting colonial expansion. It ordered that “idle” or vagrant individuals be removed from English society and sent to early colonial outposts such as Newfoundland and the West Indies. The policy aimed to relieve domestic disorder, enforce social control, and provide labor for nascent colonies, representing an early example of using colonization as a means of managing marginalized populations in the English Empire.
