Bipolarisation or bipolarization (American English) in politics, is a state where forces are organized around two rival powers, neither of which can dominate the other.
This division of the world between two poles was contested by the Non-Aligned Movement, which emerged from the Bandung Conference in 1955.
[1] Some analysts believe that after the fall of the Berlin Wall in 1989 and the collapse of the USSR in 1991, the bipolar system that emerged from the Cold War was replaced by a relatively unipolar system dominated by the hyperpower of the United States, a situation considered positive by the leaders of the United States and the United Kingdom who identify with the Western pole but criticized by French leaders who sought to assert a multipolar conception.
[2] However, the hegemony of the American pole is not very sustainable and, during the 2000s, would give way to a multipolar world sometimes described as chaotic where the powers fail to establish stable relations.
In France, bipolarisation is particularly important in a triangular election, alongside tripolarisation.
