In the early hours of June 11, armed Serbian officers, comprising a faction of the military unhappy with the current political leadership, stormed the royal palace in Belgrade. Their target was King Alexander I of Serbia and his wife, Queen Draga. The discontent within the military ranks arose from years of escalating tension due to the king's unpopular rule and perceived ineffectiveness in leadership. Officers viewed the monarchy as corrupt and out of touch with the needs of the populace, and they sought change through violent means. The brutal assault was meticulously planned; the officers entered the palace and confronted the royal couple, leading to a chaotic scene which resulted in their deaths.Following the assassination, the military took control, and power shifted rapidly in Serbia. The incident was pivotal, as it ended the reign of the Obrenović dynasty that had governed Serbia for most of the 19th century. Furthermore, the assassination of the king and queen set the stage for further political upheaval in the region. Shortly after, the leaders of the coup installed a new government, leading to the establishment of the Karageorgevich dynasty. This coup had far-reaching ramifications for Serbia's future political landscape and its role on the European stage, contributing to the rising tide of nationalism and militarism in the Balkan region leading up to World War I.
