In the long river of history, there were two wars that swept across the world like massive waves, World War I and World War II.
These wars not only changed the destinies of countless people but also deeply influenced the developmental trajectory of human society.
World War I erupted in Europe during the hot afternoon of 1914.
The assassination of Archduke Franz Ferdinand of Austria-Hungary, like a stone thrown into a calm lake, rapidly stirred up ripples.
The tensions between countries were like tightly drawn bowstrings, ready to snap at any moment.
This war lasted four years and three months, until November 11, 1918, when the Allies and Germany signed an armistice agreement, and the flames of war were finally extinguished.
Twenty years later, in 1939, Europe plunged into war once again. This time, the catalyst was a sudden attack by Nazi Germany on Poland.
Unlike World War I, World War II was a true global conflict, involving nearly all major countries and regions.
