Caucasus campaign in the context of "Cemil Cahit Toydemir"

The Armenian genocide was the systematic destruction of the Armenian people and identity in the Ottoman Empire during World War I. Spearheaded by the ruling Committee of Union and Progress (CUP), it was implemented primarily through the mass murder of around one million Armenians during death marches to the Syrian Desert and the forced Islamization of others, primarily women and children.

Before World War I, Armenians occupied a somewhat protected, but subordinate, place in Ottoman society. Large-scale massacres of Armenians had occurred in the 1890s and 1909. The Ottoman Empire suffered a series of military defeats and territorial losses, especially during the 1912–1913 Balkan Wars. This sparked fear among CUP leaders that the Armenians, whose homeland in Anatolia they considered the Turkish nation's last refuge, would seek independence. During their invasion of Russian and Persian territory in 1914, Ottoman paramilitaries massacred local Armenians. Ottoman leaders took isolated instances of Armenian resistance as evidence of a widespread rebellion, and decided to permanently forestall the possibility of Armenian autonomy or independence.

The Middle Eastern theatre of World War I saw action between 30 October 1914 and 30 October 1918. The combatants were, on one side, the Ottoman Empire (including the majority of Kurdish tribes and Circassians, and the relative majority of Arabs), with some assistance from the other Central Powers; and on the other side, the British (with the help of a small number of Jews, Greeks, Armenians, some Kurdish tribes and Arab states, along with Hindu, Sikh and Muslim colonial troops from India) as well as troops from the British Dominions of Australia, Canada, and New Zealand, the Russians (with the help of Armenians, Assyrians, and occasionally some Kurdish tribes), and the French (with its North African and West African Muslim, Christian and other colonial troops) from among the Allied Powers. There were four main campaigns: the Sinai and Palestine, Mesopotamian, Caucasus, and Gallipoli campaigns. There were four more minor campaigns in Persia, South Arabia, the Arabian interior, and Libya.

Both sides used local asymmetrical forces in the region. On the Allied side were Arabs who participated in the Arab Revolt and the Armenian militia who participated in the Armenian resistance supported by Russia during the War; along with Armenian volunteer units, the Armenian militia formed the Armenian Corps of the First Republic of Armenia in 1918. In addition, the Assyrians joined the Allies and saw action in Southeastern Turkey, northern Mesopotamia (Iraq), northwestern Iran and northeastern Syria following the Assyrian genocide, instigating the Assyrian war of independence. Turks were persecuted by the invading Russian troops in the east and by Greek troops and Armenian fedayis in the west, east, and south of Anatolia. The theatre covered the largest territory of all theatres in the war.

The First Republic of Armenia, officially known at the time of its existence as the Republic of Armenia, was an independent Armenian state that existed from May (28th de jure, 30th de facto) 1918 to 2 December 1920 in the Armenian-populated territories of the former Russian Empire known as Eastern or Russian Armenia. The republic was established in May 1918, with its capital in the city of Yerevan, after the dissolution of the short-lived Transcaucasian Federation. It was the first Armenian state since the Middle Ages.

In its first year of independence, Armenia was confined to a small territory around Lake Sevan after its invasion by the Ottoman Empire during the Caucasus campaign. Following the Armistice of Mudros, Armenia expanded its borders in the wake of the Ottoman withdrawal, leading to a brief border war with neighbouring Georgia. During its first winter, hundreds of thousands of refugees in the country who had fled the Armenian genocide died from starvation or exposure. In the spring of 1919, Armenia, with British support, incorporated the formerly occupied regions of Kars and Nakhchivan, thereby tripling in size since independence; however, Armenian control of these regions collapsed during the Muslim uprisings that erupted in the summer of 1919.

Mustafa İsmet İnönü (24 September 1884 – 25 December 1973) was a Turkish politician and military officer who served as the president of Turkey from 1938 to 1950, and as its prime minister three times: from 1923 to 1924, 1925 to 1937, and 1961 to 1965.

İnönü is acknowledged by many as Mustafa Kemal Atatürk's right-hand man, with their friendship going back to the Caucasus campaign. In the Greco-Turkish War of 1919–1922, he served as the first chief of the General Staff from 1922 to 1924 for the regular Turkish army, during which he commanded forces during the First and Second Battles of İnönü. Atatürk bestowed İsmet with the surname İnönü, the site of the battles, when the 1934 Surname Law was adopted. He served as the chief negotiator for the Ankara government, first as an army general following the defeat of invading forces during the Armistice of Mudanya talks, later as Minister of Foreign Affairs at the Lausanne Conferences (1922–1923). He secured recognition of the Turkish victory by the Allies and replacing the imposed Treaty of Sèvres with the Treaty of Lausanne. As his prime minister for most of his presidency, İnönü executed many of Atatürk's modernizing and nationalist reforms. Some claim that, İnönü gave the orders to carry out the Zilan massacre.

The Transcaucasian Democratic Federative Republic (TDFR; 22 April – 28 May 1918) was a short-lived state in the Caucasus that included most of the territory of the present-day Armenia, Azerbaijan and Georgia, as well as parts of Russia and Turkey. The state lasted only for a month before Georgia declared independence, followed shortly after by Armenia and Azerbaijan.

The region that formed the TDFR had been part of the Russian Empire. As the empire dissolved during the 1917 February Revolution and a provisional government took over, a similar body, called the Special Transcaucasian Committee (Ozakom), did the same in the Caucasus. After the October Revolution and rise of the Bolsheviks in Russia, the Transcaucasian Commissariat replaced the Ozakom. In March 1918, as the First World War continued, the Commissariat initiated peace talks with the Ottoman Empire, which had invaded the region, but the talks broke down quickly as the Ottomans refused to accept the authority of the Commissariat. The Treaty of Brest-Litovsk, which ended Russia's involvement in the war, conceded parts of the Transcaucasus to the Ottoman Empire, which pursued its invasion to take control of the territory. Faced with this imminent threat, on 22 April 1918 the Commissariat dissolved itself and established the TDFR as an independent state. A legislature, the Seim, was formed to direct negotiations with the Ottoman Empire, which had immediately recognized the state.
