Serbia

Serbia is a country in Eastern Europe that was later renamed Yugoslavia on April 27, 1992 a year after the country broke up, leaving Serbia and Montengro united.

Sparking off World War I
Gavrilo Princip, a Serb and his men recruited by him into a sub-faction called the Black Hand, were in Sarajevo to assassinate the Austrian Archduke, Franz Ferdinand because he was very unpopular to Serbia's people and made changes when he takes control in Europe. While the car, the archduke was travelling in crossed a bridge, Princip went up the car's step and used a pistol to shoot the Archduke. The Archduke was hit, along with his wife Sophie the Duchess of Honenberg in the car.

This assassination attempt was very successful for the Black Hand, but Germany blamed the Russians for the assassination on June 28, 1914 and France on the other for being an ally to Russia. The United Kingdom later blamed Germany for its alliance with Austria and on August 4, 1914 was when World War One broke out caused by many mistakes in Europe.

In the 1950s, a convoy of trucks were stopped in Yugoslavia and Allied forces attempted a promised capture of the trucks. The Soviets were critical that if the Allies got it, the top secret is exposed. They quickly managed to do everything as possible and destroyed the Allies. Then, the trucks travelled across a river on a bridge nearest to the Soviet base where the mission is accomplished.

Tiberium Universe
The Serbs joined the Brotherhood of Nod at a last minute attempt after many failures across Eastern Europe led GDI to victory. The first mission held there was to destroy a bio-research laboratory that is to launch chemical attacks across all of Europe, but Kane wasn't there at the time of this attack. General Mark Sheppard later advised the GDI Commander to not worry about Kane since the attack on the laboratory at Nis and told him to go near Belgrade to destroy a large Nod convoy heading back to Sarajevo. The two missions prove to be successful for the Global Defense Initiative.
