There are many different causes associated with each of the two world wars. In the case of WW I, Serbian separatism was the cause of the assassination of Archduke Ferdinand which was the spark that set off the war, but in order for war to be that easily started, there first had to be an unstable political standoff between two very large, arrogant and unreasonable political alliances, the Central Powers and the Triple Entente. Added to this was the long-standing territorial dispute between France and Germany about the ownership of the province of Alsace-Lorraine. Those were the main causes. In the case of WW II the main cause was German resentment about the outcome of WW I. We could say that WW II was just a rematch of WW I.
Who knows? What has caused previous wars? Religion, Communism, Power-hungry egotistical rulers, Patriotism, Imperialism, etc.
WW I was bigger than previous wars, because all the powerful nations of the world were involved on one side or the other, in two vast, opposed alliances (the Triple Entente vs. the Central Powers). No previous war had involved the whole world.
