How many years had the Russia-Ukraine war been ongoing as of 2025?

The full-scale invasion of Ukraine by Russia commenced in February 2022, marking a significant escalation of a conflict that had already simmered for years. This pivotal event dramatically reshaped the geopolitical landscape and initiated a prolonged period of intense warfare. As of 2025, the conflict had therefore been ongoing for several years, with its fourth anniversary falling in February 2026.

The roots of the conflict, however, stretch back further than the 2022 invasion. Russia's annexation of Crimea and support for separatists in eastern Ukraine began in 2014, establishing a simmering conflict in the Donbas region. The 2022 invasion represented a dramatic expansion of this existing tension, bringing full-scale war to the entire nation.

The war has led to immense humanitarian challenges, including a massive displacement of people and widespread destruction of infrastructure. It has also had profound global implications, affecting energy markets, food security, and international relations. The ongoing nature of the conflict highlights the complexities of modern warfare and the enduring struggle for sovereignty and territorial integrity.
