Context: At the end of the Balkan Wars, the extent of Greece's territory and population had increased. In the following years, the struggle between King Constantine I and charismatic Prime Minister Eleftherios Venizelos over the country's foreign policy on the eve of World War I dominated the country's political scene, and divided the country into two opposing groups. During parts of the First World War, Greece had two governments; a royalist pro-German government in Athens and a Venizelist pro-Britain one in Thessaloniki. The two governments were united in 1917, when Greece officially entered the war on the side of the Triple Entente.
