This campaign exemplifies how poorly planned military invasions can destabilize nations and alter their destinies (springboardacademy.org).
Hernán Cortés’ campaign against the Aztecs led to the collapse of an advanced civilization and centuries of colonial rule. Cortés, with about 500 soldiers, entered Tenochtitlán in 1519, where Emperor Montezuma II initially welcomed him, suspecting him to be a returning god. However, tensions escalated, leading to Montezuma’s death in Spanish custody. After a retreat and reinforcements, Cortés returned in 1521, besieging Tenochtitlán for four months before capturing it, marking the end of the Aztec Empire (britannica.com).
The First Anglo-Afghan War (1839-1842) began with the British invasion of Afghanistan, aiming to install Shah Shuja as a puppet ruler and counter Russian influence. Initial successes, including the capture of Kabul, were overshadowed by mismanagement and a lack of understanding of Afghan society. The situation rapidly deteriorated after the assassination of key British officials, which emboldened Afghan resistance led by Dost Mohammad’s son, Mohammad Akbar Khan. A disastrous retreat through the Khyber Pass resulted in the near annihilation of the British forces, with only a single survivor reaching safety. This conflict highlighted the complexities of Afghan politics and the challenges of foreign intervention (ebsco.com).

The prolonged resistance against French colonization laid the groundwork for future conflicts, including the First Indochina War and the Vietnam War. (britannica.com).
King Leopold II’s personal rule over the Congo Free State from 1885 to 1908 was marked by extreme exploitation and brutality. The indigenous population was subjected to forced labor, particularly in the rubber industry, leading to widespread abuse and atrocities. Punishments for failing to meet quotas included mutilation, such as the amputation of hands. Estimates suggest that the population declined by up to 10 million people during this period. The Belgian state assumed control in 1908, but the legacy of exploitation and depopulation continued to affect the Congo’s development for decades (en.wikipedia.org).
