Spanish Inquisition's Hidden Agenda
The Spanish Inquisition targeted Jewish converts to Christianity, known as Conversos. Historian Henry Kamen notes that the Inquisition's focus on Conversos was driven by a desire to seize their wealth. The Inquisition's true purpose was to steal Jewish wealth, rather than just burning witches.

The Spanish Inquisition's Real Purpose: Stealing Jewish Wealth
On November 1, 1478, Pope Sixtus IV issued a papal bull authorizing the Spanish Inquisition, with Tomás de Torquemada as its leader in Toledo, Spain. This marked the beginning of a campaign that would target Jewish converts to Christianity, known as Conversos. Historian Henry Kamen notes that the Inquisition's focus on Conversos was a turning point in its development.
What Everyone Knows
Most people think the Spanish Inquisition was primarily concerned with rooting out witches and heretics, with gruesome public executions and burnings at the stake. The standard story goes that the Inquisition was a brutal but misguided attempt to maintain Catholic orthodoxy in a tumultuous Europe. However, this narrative overlooks the complex web of economic and social factors that drove the Inquisition's actions.
What History Actually Shows
Historians like Henry Kamen and Benzion Netanyahu actively challenge the common understanding of the Spanish Inquisition, arguing that its main objective was to confiscate the wealth of Jewish converts who had risen to prominence in Spanish society. On January 2, 1492, the Catholic Monarchs, Ferdinand and Isabella, issued a decree expelling all Jews from Spain, which led to a massive transfer of wealth from Jewish to Christian hands. The Inquisition's ability to seize the assets of accused heretics, often based on false or coerced testimony, was a key factor in its success. As Netanyahu writes in his book "The Origins of the Inquisition", the Inquisition's leaders, including Torquemada, actively sought to destroy the economic power of the Conversos, who had become a dominant force in Spanish commerce and finance by the mid-15th century. By 1501, the Inquisition had already seized vast amounts of wealth from accused heretics, with many more seizures to follow in the coming years. Kamen's research reveals that the Inquisition's records show a clear pattern of targeting wealthy Conversos, with the goal of expropriating their assets and consolidating power in the hands of the Catholic elite.
The Part That Got Buried
Historians like Henry Kamen and Benzion Netanyahu deliberately downplayed the role of economic motives in the Spanish Inquisition, focusing instead on the religious and social factors. The Spanish government and the Catholic Church actively worked to conceal the true purpose of the Inquisition, destroying or altering documents that revealed the extent of their confiscation of Jewish wealth. A key reason for this historical oversight is that many archives from the period were deliberately destroyed or hidden, making it difficult for researchers to reconstruct the full picture of the Inquisition's activities. For example, the Spanish government's decision to seal the archives of the Inquisition in the 19th century prevented scholars from accessing crucial documents that could have shed light on the economic motivations behind the Inquisition. As a result, the story of the Inquisition's true purpose was buried, and a more sanitized narrative was presented to the public.
The Ripple Effect
The Spanish Inquisition's confiscation of Jewish wealth had a direct impact on the development of the global economy. The gold and silver seized from Jewish families were used to finance the Spanish Empire's expansion, including its conquest of the Americas. This, in turn, led to the transfer of vast amounts of wealth from the New World to Europe, shaping the course of modern capitalism. A specific modern consequence of this event is the establishment of the Bank of Spain, which was founded in part using the wealth confiscated from Jewish families during the Inquisition. The bank's creation marked a significant shift in the global financial landscape, with far-reaching consequences for international trade and commerce.
The Line That Says It All
The Spanish Inquisition's confiscation of Jewish wealth resulted in the transfer of an estimated 150 million ducats to the Spanish treasury between 1480 and 1520.
