With so many new weapons being made and strong nationalism between countries caused many countries to feel that they must be ready for war at any moment. Years went by and countries were just waiting for a reason to strike. The assassination of Arch Duke Ferdinand and his wife gave reason for Austria-Hungary to give an ultimatum to Serbia. Serbia refused the ultimatum and soon Austria-Hungary waged war against Serbia. Allies of both Serbia and Austria-Hungary joined in the war ans soon became a four vs. four country war. The assassination of Arch Duke Ferdinand is known as the trigger for WWI.
