7.1 Extractive industries: mining and agriculture

Extractive industries were the backbone of colonial Latin America's economy. Silver mining, especially at Potosí, fueled Spanish imperial expansion, while forced labor systems like mita and repartimiento exploited indigenous workers. Mercury amalgamation boosted production but harmed workers' health.

Agriculture also played a crucial role. Haciendas and plantations produced crops for local consumption and export, relying on indigenous and African slave labor. The encomienda system allowed Spanish colonists to extract labor and tribute from indigenous communities, contributing to their demographic collapse.

1 of 3

• Potosí located in present-day Bolivia was the largest silver mine in the Spanish Empire
• Produced an estimated 60% of all silver mined in the world during the second half of the 16th century
• Silver from Potosí helped finance the Spanish Empire and its global expansion
• Mining operations relied heavily on forced indigenous labor through the mita system

Mercury Amalgamation Process

• Mercury amalgamation process introduced in 1554 revolutionized silver extraction
• Allowed for more efficient processing of lower-grade ores
• Involved mixing silver ore with mercury, which bonded with the silver
• Resulted in a significant increase in silver production at Potosí and other mines
• Process had severe health consequences for indigenous workers exposed to toxic mercury vapors

Forced Labor Systems

• Mita system a form of forced labor implemented by the Spanish in Potosí and other mines
  • Required indigenous communities to provide a percentage of their adult male population for labor
  • Mitayos (mita workers) served in grueling and dangerous conditions, often leading to injury or death
  • System disrupted indigenous communities and economies, as men were taken away from their families and farms
• Repartimiento another form of forced labor used in mining and agriculture
  • Local officials (corregidores) assigned indigenous workers to Spanish employers
  • Workers received minimal wages and were often subjected to abuse and exploitation

Agricultural Production

Hacienda System

• Haciendas large agricultural estates owned by Spanish colonists or the Catholic Church
• Focused on producing crops and livestock for local consumption and export
• Relied on a combination of indigenous labor (through encomienda or repartimiento) and enslaved African labor
• Haciendas played a significant role in the colonial economy and the consolidation of Spanish land ownership

Plantation Agriculture

• Plantations large-scale agricultural enterprises focused on producing cash crops for export
• Primary crops included sugar, tobacco, cacao, and indigo
• Relied heavily on enslaved African labor, particularly in the Caribbean and Brazil
• Plantation system had a profound impact on the development of the Atlantic slave trade and the African diaspora in the Americas

Encomienda System

• Encomienda a labor system implemented by the Spanish Crown in the early colonial period
• Granted Spanish colonists (encomenderos) the right to extract labor and tribute from indigenous communities
• In exchange, encomenderos were responsible for the protection and religious instruction of the indigenous people under their control
• System facilitated the exploitation of indigenous labor and the appropriation of indigenous lands
• Contributed to the demographic collapse of indigenous populations due to overwork, disease, and abuse
