Her song "1944" about the mass deportation of Crimean Tatars under Stalin has received the highest scores both from the judges and a public vote on Sunday evening.
Jamala's song tells the story of the Soviet Red Army's deportation of nearly 250,000 Crimean Tatars in 1944.
"This song really is about my family, my grandmother. I had to write it. It is a memorial song and it is difficult for me to sing it," Jamala said in an earlier interview.
The first round of the semi-finals of the Ukrainian competition took place on February 6, the second one was held on February 13, each round offering three contestants for the finals – Jamala, The Hardkiss, Brunettes Shoot Blondes and SunSay, Pur:Pur and NuAngels (also known as neAngely).
Jamala, whose full name is Susana Dzhamaladinova, was born in Kyrgyzstan in 1983, where her family settled after her grandparents were deported under Stalin.
