The nationalist force is the motive that leads to Gavrilo Princip's assassination of Archduke Franz Ferdinand and his wife Sophie.

Gavrilo Princip was in anger by the ruling of the Austro-Hungarian empire that influenced him to assassinate the heir to the throne and his wife in order to make the Serbian country a newly independent nation.

It is because the empire was treating Serbia rudely and unfairly that started a war situation between Austria and Serbia for freedom.
