Following the death of King George I in 1913, Greece's Prime Minister Venizelos and new king Constantine were increasingly at odds. As Europe descended into the First World War, the pro-German king and the pro-Allied Prime Minister struggled politically over Greece's entry into the war with the king supporting neutrality and Venizelos favoring entry on the side of the Allies. Venizelos resigned and was succeeded by Alexandros Zaimis. In October, 1915, Venizelos left Athens and would later set up a rival government in Thessaloniki and Prime Minister Zaimis resigned. At that point, the king asked Skouloudis to form a government of national unity, including representatives of all the parties in parliament in his government. The Skouloudis government focused almost exclusively on the question of Greece's entry into World War I, and attempts to stave off the formation of a rival government in the north. Skouloudis was unsuccessful and Prime Minister Zaimis was reappointed by the king.
