Global Tensions at a Peak: The World Witnesses the Highest Number of Wars Since WWII
In recent years, it seems as though the world is becoming a more tumultuous place. The rising number of conflicts across the globe reinforces this perception, and now, concrete data supports it as well.
A recent study by Swedish academics presents some alarming figures. The year 2025 witnessed the largest number of conflicts between nations since the Second World War and the highest number of deaths since the horrific genocide in Rwanda.
A Year of Many Conflicts
In 2025, there were a staggering 65 active conflicts worldwide, a figure compiled by a globally recognized research program specializing in conflict data. The number of direct disputes between individual countries doubled from the previous year, reaching a total of eight, which is the highest since records began in 1946.
These conflicts include the wars in Russia and Ukraine, Iran and Israel, as well as battles involving India and Pakistan, Thailand and Cambodia, and Israel's involvement in Syria and Yemen. Additionally, there was a border dispute between Afghanistan and Pakistan, and a conflict in the Red Sea and Gulf of Aden involving the U.S. and U.K. against Yemen's Houthis.
An expert from the research team noted, "There is a definite escalation in state conflicts. Interstate wars were once uncommon, but recent events indicate an increase in international tension and shifts in the global security order."
The remaining 57 out of the 65 total conflicts were intrastate disputes, involving government forces battling rebel groups within the same country.
Record-Breaking Fatalities
The death toll in 2025 was the highest since 1994, with approximately 244,600 fatalities, an increase from 187,000 in 2024. Another team member noted, "Not only are conflicts becoming more frequent, but the levels of lethal violence are also escalating. Particularly striking is the dramatic surge in violence targeted at civilians, especially in Sudan."
Researchers categorized the data into several groups. "State-based violence" includes internal civil wars and interstate wars, where one or both parties are governmental entities. "Non-state violence" refers to clashes between two groups, neither of which is a state. A third category, "one-sided violence," represents violence aimed at civilians.
Out of the 65 conflicts, 13 escalated to the level of war, defined by over 1,000 battlefield deaths a year.
Deadliest Conflicts of 2025
The war between Russia and Ukraine was the most deadly, causing 62% of all battle-related deaths. Approximately 77,700 Russian and 14,000 Ukrainian lives were lost. The figures are compiled from various open sources, including social media.
The conflict between Israel and Hamas was the second deadliest, with 14,400 fatalities. However, this was a reduction from the previous year due to ceasefire agreements. The third deadliest was in Sudan with 12,200 deaths. This only includes the conflict between government forces and paramilitary groups. The violence against civilians was significantly higher, with tens of thousands killed following the capture of the city of El Fasher.
Shifting International Order
Researchers attribute the increase in global conflicts over the past decade to a transformation in the international order established by the U.S. post-WWII. Some even suggest that the significant number of wars and conflicts in 2025 mark the end of the period of relative peace and stability known as Pax Americana.
However, experts caution against attributing this trend to any specific U.S. policy changes or political leadership. Instead, they highlight the need for a broader debate on the changes in the international order post-Cold War.
Regardless of the cause, researchers warn that 2026 may not be any more peaceful. Preliminary data suggests that the trend of increasing global conflicts is likely to continue.
