The dissolution of the Soviet Union in 1991 is primarily understood to have led to what change in global political structure?

💡 Explanation:

The dissolution of the Soviet Union (the USSR) in December 1991 marked the formal end of the Cold War and the bipolar world order that had been in place since the mid-20th century. With its main rival gone, the United States was left as the sole global superpower, leading to a period often characterized as the 'unipolar moment' or a unipolar world structure. This shift redefined international relations, security, and economics.
