The Inca Empire Had No Currency On November 16, 1533, Spanish conquistador Francisco Pizarro arrived in the Inca city of Cajamarca, Peru, and was struck by the empire's vast infrastructure and complex administrative systems. Historian Pedro Cieza de León recorded the event in his book "La Crónica del Perú", noting the absence of a monetary system. Inca emperor Atahualpa's empire was a unique case in world history.
What Everyone Knows
Most people think that a well-developed monetary system is essential for building and maintaining a large empire. The standard story goes that a reliable currency is necessary for trade, taxation, and the payment of troops. However, the Inca empire, which stretched from modern-day Colombia to Chile, managed to thrive without using money as we know it. This common understanding of the Inca empire's economy is based on a superficial reading of history, but a closer examination reveals a more complex and fascinating picture.
What History Actually Shows
Historian John Murra, in his book "The Economic Organization of the Inca State", argues that the Inca empire's economy was based on a system of reciprocity and redistribution, where goods and services were exchanged without the use of money. On January 1, 1520, the Inca emperor Huayna Capac implemented a system of mit'a, a form of labor taxation where citizens worked on public projects in exchange for food, clothing, and other necessities. The Inca empire's lack of a monetary system did not hinder its ability to build extensive road networks, terracing systems, and monumental architecture. According to historian Maria Rostworowski, in her book "History of the Inca Realm", the Inca empire's economy was also based on a system of vertical control, where the state controlled the production and distribution of goods. By 1490, the Inca empire had already established a complex system of record-keeping using quipus, a type of knotted string, to track taxes, labor, and other economic activities. Historian Nathan Wachtel, in his book "The Vision of the Vanquished", notes that the Inca empire's unique economic system allowed it to maintain a high level of economic activity and growth, despite the absence of a monetary system. By 1525, the Inca empire had expanded to include a diverse range of cultures and economies, all of which were integrated into the Inca system of reciprocity and redistribution.
The Part That Got Buried
Historians like John Hemming and Nigel Davies have long noted that the story of the Inca empire's unique economic system was deliberately suppressed by Spanish conquistadors, who sought to impose their own monetary system on the newly conquered territories. The Spanish crown, eager to extract wealth from their new colonies, actively worked to erase the memory of the Inca system, which they saw as a threat to their own power. One concrete reason for this suppression was the destruction of Inca records, such as the quipus, which were intricate knotted strings used for record-keeping and accounting. By destroying these records, the Spanish effectively erased the history of the Inca empire's economic achievements, making it difficult for later historians to reconstruct the full story. Scholars like Steve Stern have argued that this destruction of records was a deliberate attempt to suppress the history of the Inca empire's economic system.
The Ripple Effect
The suppression of the Inca empire's economic system had a direct impact on the development of modern Peru, where the legacy of the Inca empire continues to be felt. The imposition of a monetary system by the Spanish led to widespread poverty and inequality, as many indigenous people were forced to adapt to a new and unfamiliar economic system. Today, the city of Cusco, once the capital of the Inca empire, is a thriving tourist destination, with many visitors drawn to its ancient Inca ruins, including the famous Machu Picchu. The Peruvian government's decision to adopt a monetary system based on the US dollar has also had a lasting impact on the country's economy, with many Peruvians still struggling to make ends meet.
The Line That Says It All
The Inca empire's economic system was dismantled by the Spanish in a matter of decades, leaving behind a legacy of poverty and inequality that still affects modern Peru.
