When World War I began, Italy at first remained neutral, despite being part of the Triple Alliance (albeit it was signed on defensive terms and Italy objected that the Sarajevo assassination did not qualify as aggression). However, in 1915, Italy signed several secret treaties committing her to enter the war on the side of the Triple Entente. Most of the politicians opposed war, however, and the Italian Chamber of Deputies forced Prime Minister Antonio Salandra to resign. At this juncture, Victor Emmanuel declined Salandra's resignation and personally made the decision for Italy to enter the war. He was well within his rights to do so under the "Statuto," which stipulated that ultimate authority for declaring war rested with the crown.
