Looking back at the events that led up to the Second World War, it’s easy to see that the world was barreling toward disaster long before the first shot was fired.

The political, social, and economic unrest in the 1920s and 1930s made the second great conflict of the 20th century feel inevitable.

What’s even more unsettling is how some of the signs from that era are reappearing today in a world that, while vastly different, still faces the prospect of geopolitical tensions boiling over.

So, what were the warning signs that a world-shaking war was on the horizon, and what lessons can we learn from them? And more importantly, how do today’s tensions echo those from the past? Let’s take a closer look.

Signs of a Looming Conflict

Warning Sign #1:| The Rise of Nationalism and Authoritarianism

One of the most obvious precursors to World War II was the rise of nationalism and authoritarian regimes across Europe.

After the Treaty of Versailles ended World War I, many countries were left dealing with the aftermath of economic and social instability.

Germany, in particular, suffered greatly under the harsh terms of the treaty, leading to widespread resentment and the eventual rise of Adolf Hitler and the Nazi Party.

Hitler played into the German people’s desire for national pride and revenge, promising to rebuild the country and restore its former glory.
