|World War I Fueling Point|
The assassination resulted in anti-Serbs riots in Sarajevo. Austria-Hungary wanted to end the Serbian influence in Bosnia. The Serbians didn't accept the ultimatum served by Austria-Hungary, which resulted in the later declaring a war with Serbia.
Russia sided with Serbia and mobilized its troops. Fearing the Russian presence in Central Europe, Germany opposed the mobilization and declared war against the Russians.

With Belgium located between Germany and France, and the Belgians not allowing the Germans easy access to France through its land, the Germans declared war on Belgium.
Irked by the war against Belgium, Britain jumped into the fray and declared war against the Germans.
So it was Germany, Austria-Hungary + others on one side, the Central Powers, against France, Russia, Britain + others, the Allied Powers.
Political and Military positioning led to a confluence of power and conflict of interest.
The rest, as we all know, is World War I !
It resulted in 9.9+ Million military deaths, 21+ Million wounded people, and 7.7+ Million people missing. Did we need all of this??
In hindsight, it will be worthwhile to read the comments by Hew Strachan, a military historian. He said, "Whether an equivocal and early response by Serbia (to the ultimatums) would have made any difference to Austria-Hungary's behavior must be doubtful. Franz Ferdinand was not the sort of personality who commanded popularity, and his demise did not cast the empire into deepest mourning."
Need I say more?
P.S. Think twice, before overreacting.
