How Did World War II End

The Final Year of War

By early 1945, the Allied Powers had gained the upper hand on every front.
In Europe, the Western Allies — led by the United States, Britain, and France — advanced through Germany from the west, while the Soviet Union pushed from the east.
In the Pacific, American forces closed in on Japan, capturing key islands like Iwo Jima and Okinawa after brutal fighting.

The End of World War II – From Ruins to Peace

After six years of global conflict, the Axis Powers were collapsing under the combined weight of military defeat, economic exhaustion, and overwhelming Allied firepower.

The Fall of Nazi Germany

The turning point in Europe came with the invasion of Germany itself.
In April 1945, Allied and Soviet forces encircled Berlin, the heart of Hitler’s Third Reich.
After weeks of street fighting, Adolf Hitler took his own life on April 30, 1945, inside his bunker beneath the city.

With their leader dead and the capital in ruins, German forces began surrendering across the continent.
On May 7, 1945, Germany signed an unconditional surrender at Reims, France. The following day, May 8, was declared Victory in Europe Day (V-E Day) — the official end of the war in Europe.

Europe celebrated, but the war was not yet over. In the Pacific, Japan continued to fight on fiercely.

The End of the War in the Pacific

Japan’s empire still stretched across much of East and Southeast Asia. Despite heavy losses, its leaders refused to surrender, choosing instead to prepare for a final defense of the Japanese homeland.

In July 1945, at the Potsdam Conference, the Allies issued a declaration calling for Japan’s unconditional surrender — or face “prompt and utter destruction.”
Japan did not respond.

To avoid what was expected to be a costly invasion of Japan, the United States made the fateful decision to use its newly developed atomic bomb.
On August 6, 1945, the first bomb was dropped on Hiroshima, destroying the city and killing tens of thousands instantly.
Three days later, a second bomb struck Nagasaki.

At the same time, the Soviet Union declared war on Japan and invaded Manchuria, crushing Japanese forces there.

Japan’s Surrender

Faced with devastation and the loss of millions of lives, Emperor Hirohito intervened.
On August 15, 1945, he addressed the Japanese people in a historic radio broadcast, announcing the nation’s surrender — the first time a Japanese emperor had ever spoken directly to his citizens.

The formal surrender took place on September 2, 1945, aboard the USS Missouri in Tokyo Bay.
Representatives of the Allied and Japanese governments signed the documents that officially ended World War II.

The Aftermath of Victory

With the guns finally silent, the world faced both relief and grief.
More than 70 million people had died, cities lay in ruins, and entire nations had to be rebuilt.
The Allied powers began a long process of reconstruction and justice — including the Nuremberg Trials, which prosecuted major Nazi leaders for war crimes.

The United Nations (UN) was founded in 1945 to promote peace and cooperation between nations, aiming to prevent another global catastrophe.
Meanwhile, the alliance between the United States and the Soviet Union soon gave way to ideological rivalry — beginning the Cold War that would define the next half-century.
