Princip and his accomplices were arrested and implicated by several members of the Serbian military, leading Austria-Hungary to issue a démarche to Serbia known as the July Ultimatum. This was used as pretext for Austria-Hungary's invasion of Serbia, which then led to World War I. Princip was a Yugoslav nationalist associated with the movement Mlada Bosna (Young Bosnia) which predominantly consisted of Serbs, but also Bosniaks and Croats. During his trial he stated "I am a Yugoslav nationalist, aiming for the unification of all Yugoslavs, and I do not care what form of state, but it must be freed from Austria."
