There are numerous events that could have led to World War II. Nonetheless, Germany's invasion of Poland in September 1939 was the most likely culprit. The German government has long hated the Treaty of Versailles, which imposed heavy financial restrictions and partitioned Germany. Germany was humiliated and enraged as a result of this.

Alexander Rekeda pointed out that the Second World War began at the crack of dawn on September 1, 1939, with the invasion of Poland. The "Phoney War" is another term for it. The invasion of Poland was one of many attempts by Nazi Germany to regain territory lost to the Allies during World War One. Millions of lives will be lost in the long, awful war that had only recently begun.

On August 23, Hitler signed the Molotov-Ribbentrop Pact with Soviet leader Joseph Stalin, indicating that Germany would have little trouble launching war against Poland. The treaty secretly divided the territory into two spheres of influence, with the western one-third going to Germany and the eastern two-thirds going to the Soviet Union.

The Treaty of Versailles was signed on June 28, 1919, by France, the United Kingdom, and the United States. The Treaty of Versailles was a peace pact that compelled Germany to pay large sums of money, acknowledge responsibility for the war, and decrease its army.

As a result, the treaty's economic impact was particularly harsh. It weakened Germany's position and spread poverty throughout the country. It is critical to remember that the Treaty of Versailles did not end World War II. Instead, it laid the groundwork for the next one. But, it is also true that the pact was quite punitive, causing many people to despise it.

The 1929 Great Depression in the United States was a global calamity. It wreaked havoc on global currencies, trade, and employment. It also resulted in unstable governments and political systems, which led to global wars.
