The signing of the Tripartite Pact on March 25, 1941, marked a significant moment in Yugoslavia's tumultuous history during World War II. This agreement aligned the Kingdom of Yugoslavia with the Axis powers, comprising Germany, Italy, and Japan, and aimed to fortify their military influence in southeastern Europe. The decision to join the Axis occurred against a backdrop of increasing pressure from Nazi Germany, which had rapidly expanded its control over Europe, including neighboring countries like Hungary and Bulgaria, that had already entered the pact.

King Peter II, who ascended the throne in exile, found himself in a precarious position as factions within the country debated the merits of siding with the Axis or maintaining a stance of neutrality. The signing took place in Belgrade's government complex, where the prime minister, Dragiša Cvetković, represented the government. However, this decision sparked widespread outrage among the military and the populace, who were deeply opposed to Nazi influence and ambitions.

The backlash from signing the pact was immediate and severe. Just two days later, on April 27, 1941, a coup led by General Dušan Simović overthrew the pro-Axis government, leading to a withdrawal from the Tripartite Pact. This act of defiance, however, prompted a swift military response from Germany, culminating in the invasion of Yugoslavia. The subsequent occupation had devastating effects as Yugoslavia fell apart into factions, leading to a brutal civil war and significant human suffering over the next several years.
