The other main trigger was the Schleiffen Plan as this also made the alliances come together and fight.
A world war is different to a normal war as it includes the whole world attacking each other with at least two or more sides.
If it was just a war it wouldn't have such a big impact on the rest of the world but if it is a world war you have no way but to end the war.
Section 1
The long term causes would be nationalism were your proud of your country and want to be prouder by taking over another country.
Arms Race is when you have the arms but you are afraid the other countries have more than you so you attack first.
Imperialism which is were you worry that the other empires are getting too big so you take them down, by invading them. You also get in there now in case they manage to get more alliances.
Alliances are the main part of the war. They are when you have an Ali but you must help them out when they are in trouble or are just in war.
I think this was one of the main reasons as the Schleiffen plan was commenced the alliances backed each other up and eventually started a world war.
The Schleiffen plan was also the long term cause as it caused the alliances to start taking place. As Germany wanted to attack France quickly they went through Belgium, but Belgium retaliated.
This was because Germany thought that they would be big enough and Belgium wont resist a German attack and also they thought it would take 6 weeks for France to be taken over and that it will take roughly 6 weeks for Russia to mobilise and also that Britain will remain neutral.
Germany were way too confident with their plan. This didn't lead them to their victory.
Really the war was only created by Germany with their Schleiffen plan but also if it wasn't for the alliances there wouldn't be a world war in the first place.
Everything is very much linked together as they are all part of each other.
If the Schleiffen plan wasn't brought together the alliances would have made a war any way and without the Schleiffen plan then most of Europe would have had a war any way.
I still think that the main cause was Alliances. Without it, it wouldn't have made a war as people would have been too scared.
Conclusion
Overall I have to a conclusion of the Alliances. If there was no Alliances there would not of been an assassination or even Austria invading Serbia.
I think that a long term cause and a trigger factor could be the same as the alliances could have made a long term cause into a trigger.
I do think that there is a country to blame and that it is Germany as they thought they could over rule France and Russia without the alliances helping such as Britain.
I also think that at 1915 was when it was unavoidable for Britain to escape World War 1. As that was when they started helping the French as an alliance.
In the end of this essay I think that the two main causes of the first world war was the Alliances and the Schleiffen plan.
