The fall of the Berlin Wall in 1989 marked the beginning of a unipolar era led by the United States.
US hegemony translated into almost uncontested leadership in political, military and economic arenas.
The US faces challenges to its dominance from China and resurgent Russia.
The emergence of populist nationalism and authoritarian figures challenge international institutions.
New multinational bodies such as the BRICS offer a counterweight to Western institutions.
The contemporary world is multipolar with emerging powers like India, South Africa, Turkey and Brazil.
A multipolar world presents more complex diplomacy and risks of instability.
Conflicts and wars multiply in a multipolar world with the US, China, and Russia as main actors.
The hostility between traditional and emerging powers in different areas makes it difficult to consolidate stable multipolarity.
Conclusion: The world has evolved from a unipolar hegemony to a turbulent multipolarity, where conflicts and instability abound. However, the world order continues in transformation, and it remains unclear whether multipolarity is a passing stage or a permanent feature.
