The First World War left a lasting legacy of physical, psychological, and social devastation. Millions of soldiers were left with debilitating injuries, disabilities, and mental health issues. The war also caused widespread destruction of infrastructure, economies, and communities. In addition, the war contributed to social unrest, political instability, and the rise of totalitarian regimes in Europe. The long-term effects of the war continued to shape the world for decades after the armistice, leaving an enduring scar on the 20th century.
