The UK's hopes of a Eurovision Song Contest triumph were dashed as Ukraine was crowned winner of the competition.
Jamala won for her political song 1944 and pleaded for "peace and love" as she collected her trophy.
She said her song is dedicated to her great-grandmother and is reportedly about Stalin, Crimea and claims of ethnic cleansing.
After accepting the Eurovision trophy, she said: "I know that you sing a song about peace and love, but actually, I really want peace and love to everyone."
Thrusting the glass microphone in the air she yelled: "Thank you Europe - welcome to Ukraine."
Australia were ahead for much of the scoring but came in second.
They were knocked to second place after the public vote was taken into account.
Russia's Sergey Lazarev, who had been the favourite going into the competition, came in third.
British hopefuls Joe and Jake came a disappointing 24th out of 26th in the contest for their pop song You're Not Alone.
They tweeted fans to say they hoped they did the UK proud.
Justin Timberlake provided half-time entertainment during the competition, opening his special guest performance with his hit Dance With Me before moving on to his new single Can't Stop The Feeling.
The audience in Stockholm were on their feet and waving flags from all over Europe as the star performed one of his signature high-energy dance routines in front of a brass section and backing singers.
After his performance, commentator Graham Norton said Justin will not be the last big American star to appear at the music competition "now they have realised this is the Super Bowl of Europe".
