The causes for each were not entirely the same. Before WWI countries were content to wage war on each other relatively indirectly, for control of the colonies and their resources. After WWI, the possibility of directly attacking other European countries was once again raised. WWI started due to the assassination of Archduke Ferdinand. It involved several countries because a lot of countries had agreed to help each other if war came. It was called The War to End all Wars, or The Great War.

World War II started when Germany again began it's expansion into Europe A lot of countries didn't like that, and so there was another huge war. It didn't make sense to say 'The War' anymore, and so they came to be called World War 1 and World War 2. The Japanese, expecting America to be occupied in the European war, and considering America as a threat to it's Asia-Pacific hegemony declared war on the Americans.

World War 1 came first. Technology was relatively primitive, with most of the war being done in trenches. Early airplanes were used. Poisonous gas was deployed for the first time.

In World War 2, tanks were used as the main deployment in many areas. Planes had improved, and bombers and fighters were heavily used. Submarines were also more heavily used. Encryption codes for secret also became more complex.

In both wars Germany was fighting against Great Britain, France, Russia and United States and in both wars Germany lost the war and territory.

In First World War, the Ottoman Empire (Turkey) carried genocide against Armenians; in

Second World Germans committed genocide against Jews and Romanies ('gypsies').

But while First World War was mostly the war between countries, Second World War was also the war of ideologies, such as Fascism and Communism.

Casualties and damages in the Second World War were on larger scale.

The Americans did not directly join WW2 immediately; they only joined after they were attacked at Pearl Harbour.

World War 1 came first, but there were a lot of differences. Many of the same countries were involved in World War 2, but the weaponry was more advanced and the idealogies had changed. Also, World War 2 lasted longer, and more people were killed in it worldwide.

World War One or the Great War was mostly a trench war. It mainly consisted of trench combat. One side would wait in there trench while one advanced and attacked. World War Two was a war where the Germans Italians and Japanese tried to conquer the world (Mainly Europe and the Pacific) Then the Allied powers went and retook the land.
