Causes of WW1

The main causes of WW1 was militarism and the fail of the alliance system. It was also caused by the grown hatred toward other countries which supported the rising of nationalism in European countries. Economic and imperial competition and fear of war prompted military alliances and an arms race, which further escalated the tension contributing to the outbreak of war amongst the countries. Another reason why WW1 broke out was because of the Assassination of Franz Ferdinand.
