On 21 March 2014, Russia formally annexed Crimea, a move that sparked international condemnation and escalated tensions with the West.
Following a disputed referendum, held under Russian military presence, Moscow declared Crimea part of its territory, citing historical ties and the will of the local population.
The annexation, deemed illegal by Ukraine and much of the global community, led to sanctions against Russia and a deepening geopolitical rift.
This event marked a turning point in post-Cold War relations, foreshadowing years of conflict and diplomatic standoff between Russia and the West.
