World War I has affected many nations along with their citizens. WW1 was known as "the great war". One of the many causes to World War I was the rise of nationalism toward many countries.
The people who wanted independence led to a to series of national struggles and problem for their independence among the Balkan people.
Another cause for WW1 was the need for their own country, many people got tired they wanted to have their own country so they started becoming rivalries with other country around Europe. Another reason of the war was because of the Balkan wars and the assignation of Franz Ferdinand. Balkan states were very unstable at the start of the 20th century as the region was under foreign rule and the Balkans wanted self-rule.
In protest against Austria's control, terrorists in Bosnia assassinated Archduke Franz Ferdinand and his wife at around June 1914.
The Bosnians were backed by Serbia and Russia; Germany sided with Austria, against Serbia. Of course After Franz Ferdinand was shot, Serbia took advantage and was able to take Austro-Hungarian Land.
Militarism came into place all the countries within Europe were creating large armies before the war years. Every country was ready for the war they were planning and getting their army ready; it was just a matter of time. Secret battle plans lead to spies, which also lead to other nations feeling scared and suspicious.
The Collapse of the Alliance System came because the European government fells distrust and he made them feel suspicious. Everyone was so suspicious they never talked about specific plans if a war was to come soon because they were scared that they might be destructed.
