It is common for one war to lead to another. Often, one war creates so much ruin, another war follows as an attempt to “rebuild” from the devastation of what happened previously. The four-year First World War (1914-1918) left the world unstable and uncertain of what would happen after the devastation of that war. While World War I caused problems for the world, the nation's instability after World War I caused a war that would prove far more destructive than anyone could have imagined. The causes of the Second World War were multiple and it is difficult to pinpoint which cause had the greatest impact on the creation of the war, although most would agree that Adolf Hitler's involvement in the years leading up to the Second World War was one of the largest. causes of the war and Hitler was involved in multiple causes of the Second World War.
