In the Ottoman empire.
The Armenians, of whom between 600,000 and 1,8 million were systematically killed. The Turks themselves however maintain that this was an unfortunate case of ethnic violence and that death figures of Armenians are exaggerated, but among scholars there is very little doubt that the killings were well-organized by the Ottoman government.

The worst massacre of all time was the Nanking Massacre in 1937.
The Turks accused the Armenians of aiding the Russians in World War I to circumvent Ottoman defenses in the East with minimal evidence. Now they accuse the Armenians of trying to defame their name because of the Armenian request that the world recognize the Armenian Genocide.
The Armenian Genocide
In 1915 there was a massive genocide when the Turks killed millions of Armenians so many left to find a better place to live and to escape.
There were Kurdish militias that assisted the Young Turks in hunting down and butchering Armenians. Unlike the Turkish government, Kurdish leaders in subsequent decades have admitted their role in the genocide and requested forgiveness for their crime.
They never did. The turks to this day deny its happening and as of yet the turks have not addmitted to the murder of more than a million armenians
It ended in 1917, but there were further massacres of Armenians by the Turks in 1922.
