Expedition to Mexico, 1519 (Edexcel GCSE History): Revision Notes
Expedition to Mexico, 1519
Overview of Cortés's expedition
In 1519, Hernán Cortés led a Spanish expedition to Mexico that would dramatically change the course of history. This expedition resulted in the collapse of the mighty Aztec Empire and established Spanish control over Central America. Understanding the motivations behind this expedition and the circumstances surrounding Cortés's arrival helps explain one of the most significant conquests in world history.
This expedition represents one of the most pivotal moments in world history, marking the beginning of Spanish colonial dominance in the Americas and the end of one of the world's most powerful indigenous empires.
Spanish motivations for the Mexican expedition
The Spanish had several compelling reasons for launching an expedition to Mexico in 1519. Previous explorers who had returned the year before brought back exciting reports of beautiful gold and silver objects, along with amazing stories of stone cities built by the Maya people. These tales of wealth sparked intense interest among Spanish colonial officials.
Diego Velázquez, the ambitious governor of Cuba, saw an opportunity to gain both wealth and fame by claiming new territories for Spain. The expedition also served religious purposes, as the Spanish viewed it as an opportunity to spread Christianity among the indigenous populations. This combination of economic, political, and religious motivations made the Mexican expedition highly attractive to Spanish colonial authorities.
The Spanish colonial system was driven by what historians call the "Three Gs": Gold (economic gain), Glory (political power and prestige), and Gospel (spreading Christianity). The Mexican expedition perfectly embodied all three motivations.
For Cortés himself, who had been working for Velázquez in Cuba and had already become wealthy, the prospect of discovering even more treasure made him eager to lead an expedition to Mexico.
The rivalry between Velázquez and Cortés
A significant power struggle developed between Governor Velázquez and Hernán Cortés that would shape the expedition's outcome. Initially, Velázquez appointed Cortés as the commander of the expedition to Mexico, trusting him to establish trading relationships with the coastal tribes.
However, Cortés had different ideas. Rather than simply establishing trade as instructed, Cortés planned to settle permanently on the mainland and claim territory for himself. When Velázquez realised that Cortés might ignore his orders and potentially take control of any discovered territory, he changed his mind about the expedition.
The conflict between Velázquez and Cortés was crucial to the expedition's outcome. Cortés essentially went rogue, departing without official permission and operating independently of Spanish colonial authority in Cuba.
Velázquez decided to put Cortés in charge just before the expedition was scheduled to depart, but his change of heart came too late. Cortés had been warned about Velázquez's intentions and had already left Cuba with 11 ships, approximately 600 men, and 100 enslaved Cubans before Velázquez could stop him.
Mexico in 1519 - the Aztec Empire
When Cortés arrived, Mexico was dominated by the powerful Aztec Empire, which had existed for hundreds of years under the rule of Emperor Montezuma. The empire operated on a tribute system where rulers of conquered cities could remain in power as long as they paid tribute and supplied the Aztecs with warriors when required.

Despite the Aztec Empire's apparent strength, it faced significant internal challenges. Many tribes within the empire resented Aztec rule and were potential allies for Cortés and the Spanish against their Aztec overlords. This internal dissatisfaction would prove crucial to Spanish success.
The Aztec capital, Tenochtitlan, was located in the centre of Lake Texcoco and housed approximately 300,000 people, making it larger than any European city at the time. This impressive urban centre represented the heart of Aztec civilisation and power in Central America.
Tenochtitlan's size and sophistication amazed the Spanish conquistadors. The city featured elaborate canal systems, magnificent temples, and advanced agricultural techniques that rivalled or exceeded European urban planning of the era.
Cortés's arrival and early actions
In March 1519, Cortés formally landed in Mexico and claimed the territory for Spain. His first major military action took him to the Tabasco River, where he won a decisive victory against the local Maya tribes. This victory was largely due to the Spanish advantages of horses and artillery, weapons that the Maya had never encountered and could not effectively counter.
Following this victory, Cortés received 20 young indigenous women as part of the surrender terms, and he converted them to Christianity. Among these women was Malinche, who would become both his mistress and his interpreter. Malinche proved invaluable to the Spanish cause as she could communicate with both the Aztecs and other indigenous tribes on Cortés's behalf, positioning him to negotiate and form alliances with various groups.
Malinche, also known as Doña Marina, became one of the most important figures in the Spanish conquest. Her linguistic abilities and cultural knowledge were essential to Cortés's success in navigating complex political relationships between different indigenous groups.
