Researchers are examining historical disinformation campaigns targeting the legacy of Argentine liberator José de San Martín during the 19th century.

This analysis is significant because it draws parallels between modern fake news and the strategic use of propaganda to destabilize national figures. By studying these early efforts, historians can better understand how narrative manipulation has been used to shape political identity in South America.

The study focuses on the specific tactics used to discredit San Martín, who led the liberation of Argentina, Chile, and Peru. These early campaigns often utilized printed pamphlets, and coordinated reports to spread falsehoods about his motivations and political alliances.

Historians said that these efforts were not random but were calculated moves by political rivals. The goal was to erode public trust in the military leader and shift the balance of power during the formation of independent states.

While modern disinformation spreads via digital algorithms, the 19th-century version relied on the control of printing presses and the manipulation of diplomatic correspondence. The core objective remains the same: the erasure or distortion of historical truth to serve a current political agenda.

Despite the lack of digital footprints, the remnants of these campaigns are visible in archival documents. These records show a pattern of coordinated attacks that mirror the structural nature of contemporary influence operations.

Modern fake news has roots in 19th-century strategic propaganda.

This study suggests that disinformation is not a byproduct of the internet age but a long-standing tool of political warfare. By identifying the patterns of the anti-San Martín campaigns, scholars can identify a timeless blueprint for how state and non-state actors attempt to rewrite history to delegitimize leadership.
