<section><h2 class="h2">World War II</h2><p class="p">
World War II (WWII or WW2), also known as the Second World War (after the recent Great War), was a global
war that lasted
<mark>from 1939 to 1945</mark>, though related conflicts began earlier. It involved the vast majority of the
world's nations—including all of the great powers—eventually forming two opposing military alliances: the
Allies and the Axis. It was the most widespread
war in history, and directly involved more than
<mark>100 million people from over 30 countries</mark>. In a state of "total war", the major participants
threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the
distinction between civilian and military resources.
Marked by mass deaths of civilians, including the
<mark>Holocaust</mark> (during which approximately 11 million people were killed) and the strategic bombing
of industrial and population centres (during which approximately one million people were killed, including
the use of two nuclear weapons in combat),
it resulted in an estimated 50 million to 85 million fatalities. These made World War II the deadliest
conflict in human history.
