It is due to the balkans problem
In my personal opinion, the Balkans has been a source of conflict for 1000 years. It is a principal trade route from Asia to Europe.
Russia, Britain, France, Balkans, etc.
Many things, but one was Austro-Hungarian domination in the Balkans.
The two countries that tried to dominate the Balkans in world war 1 were Austria-Hungary and the Ottoman Empire. This conflict, due to alliances with other countries, is one of the causes of WW1 as the countries took sides.
"because of the nationalistic spirit that was causing revolts and rebellion in that area prior to World War I. It was where "the Great War," World War I, began with the assassination of Archduke Ferdinand."
The Civil War of Balkans revolved around preserving the unity of Yugoslavia. The goal was to crush the secessionist governments.

the USA entered the war because of the bombing of Pearl harbour on (Dec.7 1941) which was anAmerican Navy Base.
I do not understand your question completely but i think you mean where did it happen which was in France, the Middle East, Russia, and in the Balkans
Prior to and following the outbreak of the First World War, the Balkans were considered to be the "powder keg of Europe." This is due to the overlapping alliances of the strongest nations and the volatility in that particular region. One significant action could, and, with the assassination of Archduke Franz Ferdinand, did, ignite a world war.
It did not escalate into a full blown war because both sides knew that if it did it would result in nuclear warfare, and if that happened it would be the end of humanity as we know it.
Apart from the brouhaha in the Balkans, it was because of the pacts between various countries agreeing to get involved if they were attacked.
