The ending of the Armenian Genocide was very connected with the beginning.

1912 after losing the war with the Balkans and losing 70% of the land they had, the Ottoman Empire thought that they no longer could live peacefully with Christians. So they planned the Armenian Genocide in advance. When the WW1 started that was an oppurtunity for them, they insisted all the Armenians to give in their hunting weapons for the army to fight, those who didnt have a gun they had to buy one and give to the army, that way they were sure that no weapons were left with the armenians. The Armenian Genocide started in the Turkish parliament by arresting all the Armenian diplomats, lawyers, doctors and leaders. They got all Armenian men for the "war" and killed them all. The towns and the villages were left with no men, only elderly, women, and children. Then the "deportation" started people lost their homes, wealth, homeland and their lifes on the deserts. 1.5 million people were killed. 1923 thats when the Ottoman Empire collapsed, Armenian Genocide ended, and modern Turkey was established by Kemal Ataturk. Talaat Pasha and two others were convicted for the Armenian Genocide in absentia. They were later killed in Germany by Armenian assasins.

It is generally assumed that the Armenian genocide was limited to the period 1915-16; and it is certainly true that this was the period when most of Turkey's Armenians were murdered; deported and starved to death; or, if male children, forcibly converted to Islam.

But the genocide did not end then. Numbers of Armenians were still being hounded out of their homes in 1917. As late as March 1918, Enver Pasha issued orders that all Armenians over the age of 5 were to be executed; and massacres continued until at least September 1918, when 30,000 Armenians were murdered over a 3-day period in Baku.

The Allied victory over the Turks brought a brief respite to surviving remnants of the former Armenian population. Trials began of various Turkish officials accused of leading the genocide.

But in 1920, with Kemal Ataturk now heading the Turkish goverment, the massacres resumed: in February 1920, 10,000 Armenians were reported murdered in Marash. Turks accused in the genocide trials began to escape from prison with amazing regularity. And the killings continued. In November 1920, less than 500 Armenians from a population of 10,000 survived an attack in Hajen.

Nor did it stop in 1922. In September, the Turks regained control of Smyrna from Greek forces. Thousands of Armenians were butchered in the aftermath.

But that was the end of the mass killings --- if only because there were virtually no Armenians left to kill.

It was left to Hitler to mockingly speak their epitaph, within days of attacking Poland and starting WW2. Hitler gave orders "to kill without pity or mercy all men, women, and children of Polish race or language," and concluded by saying: "WHO STILL TALKS NOWADAYS OF THE EXTERMINATION OF THE ARMENIANS?"
