Alexandros Zaimis was re-elected as Prime Minister a further five times. He was appointed Prime Minister under King Constantine I to succeed Venizelos in October 1915, but resigned a month later when his government failed to receive a vote of confidence. In 1917, Zaimis served again as Prime Minister under King Constantine I, while Eleftherios Venizelos led a rival government controlling northern Greece. Under Entente pressure, he resigned in favor of Venizelos in June of the same year. During World War I, he was generally supposed to favor neutrality for Greece, but to be personally in favor of the Allies.
