World War II, often abbreviated as WWII or WW2, was a global war that lasted from 1939 to 1945. The vast majority of the world's countries—including all of the great powers—eventually formed two opposing military alliances: the Allies and the Axis. In a state of total war, directly involving more than 100 million personnel from more than 30 countries, the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources.
World War II was the deadliest conflict in human history, marked by 50 to 85 million fatalities, most of whom were civilians in the Soviet Union and China. Tens of millions of people died due to genocides (including the Holocaust), premeditated death from starvation, massacres, and disease. Aircraft played a major role in the conflict, including in the strategic bombing of population centers, the development of nuclear weapons, and the only two uses of such in war.
In the United States, the president during World War II was Franklin D. Roosevelt. He served from 1933 to 1945 and was the only president to be elected to more than two terms.

Only president elected to more than two terms

Roosevelt was first elected in 1932, in the midst of the Great Depression. He won re-election in 1936, 1940, and 1944. His presidency is often considered to be one of the most consequential in American history.
There are a number of reasons why Roosevelt was able to win four terms in office. First, he was a very popular president. He was seen as a strong and decisive leader who was able to help the country through the Great Depression and World War II.
Second, Roosevelt was able to take advantage of the fact that the Republican Party was divided during his time in office.

Established the Manhattan Project
The Manhattan Project was a top-secret research and development project that produced the first atomic bombs during World War II. The project was established by the United States government in 1942, and it was led by physicist J. Robert Oppenheimer.
The Manhattan Project was one of the most ambitious and expensive scientific undertakings in history. It employed over 130,000 people at its peak, and it cost over $2 billion (equivalent to $26 billion in 2021). The project was also shrouded in secrecy, and its existence was not publicly acknowledged until after the war.
The Manhattan Project was a success. On July 16, 1945, the first atomic bomb was detonated at the Trinity test site in New Mexico. Two weeks later, atomic bombs were dropped on the Japanese cities of Hiroshima and Nagasaki. These bombings led to the surrender of Japan and the end of World War II.
The Manhattan Project had a profound impact on the world. It ushered in the nuclear age, and it raised serious questions about the ethics of using nuclear weapons.
President Franklin D. Roosevelt played a key role in the establishment of the Manhattan Project. He was the one who authorized the project and provided the funding for it. Roosevelt was also kept informed of the project's progress, and he was the one who made the final decision to use atomic bombs against Japan.
Died in office in 1945
Franklin D. Roosevelt died in office on April 12, 1945, just weeks before the end of World War II. He was 63 years old.

Despite his health problems, Roosevelt continued to work long hours. He was determined to lead the United States to victory in World War II. However, the strain of the war took a toll on his health. In April 1945, he suffered a massive cerebral hemorrhage and died.
Roosevelt's death was a major blow to the United States and to the Allied cause. He was a beloved leader who had guided the country through some of its darkest days. His death came at a time when the war was still raging, and it cast a pall over the celebrations that followed the Allied victory.
Roosevelt's death also had a profound impact on the course of American history. He was succeeded by Harry S. Truman, who had very different views on domestic and foreign policy.
