A world war is an international conflict that involves all of the principal countries of the world. Two of these conflicted in the first half of the 20th century. These two conflicts were referred to as world wars because they involved a lot of different people. Whether or not these wars were truly world wars depends on the definition of the term used. Read on for a brief history of each world-wide conflict and how it shaped the course of human history.

The conflict was so large that millions of people were displaced, and many were killed or injured. The fighting was particularly intense in France and Belgium, where the war began on April 6, 1917. The United States declared war on Germany on April 6th, and the following day, it allied with the Allies in the Pacific. In addition, the blockade of German ports helped to shift the balance of power away from Germany, which helped the Allies win the war.

There are a number of different theories about the causes of world wars, including the ‘timetable theory’. The AJP Taylor ‘timetable theory’ points to the delicate plans that go into mobilization. The Schlieffen Plan, a German-led plan to conquer France, was a shrewd move that brought Britain into the war. Although the United States, Britain, and France were the three major powers in the conflict, many people attribute the conflict’s scale to imperialism and capitalism.
