Pre-contest favourite Loreen gave a strong performance and surprised no-one with her early lead on the scoreboard. Euphoria has appeared in the charts in 14 countries, and topped the charts in five. Following her victory, Sweden will host the contest next year.
Donny Montell, of Lithuania, provided some early entertainment in the 57th annual Eurovision Song Contest with some enthusiastic dancing during his performance of pop track Love Is Blind.
Runners up, the Buranovo Grannies, were well received by some 20,000 spectators in Baku's Crystal Hall. The six choir members hope to rebuild their local church with any proceeds from their track Party for Everybody, and their Eurovision exposure.
The Grimes twins once again represented Ireland at this year's Eurovision, with Waterline. But despite reasonable odds with the bookies - and an eye-catching routine - Jedward finished in 19th place, slipping 11 places on their previous performance in 2011.
Pastora Soler of Spain gave a passionate performance of Quedate Conmigo (Stay With Me). Earlier in the week, the Spanish entry was hit by controversy after the singer suggested she had been asked not to win, to avoid Spain having to foot the bill for next year's contest.
Turkey's somewhat kitsch entry, Love Me Back - perfomed by Can Bonomo, proved a popular choice with the home crowd. The song received 12 points from Azerbaijan. Countries are not allowed to vote for themselves, but typically favour neighbours and allies.
Azerbaijan's Sabina Babayeva told BBC One's Graham Norton that she was a "big fan" of Engelbert Humperdinck. Her track When The Music Dies was written by the same team behind 2011 Eurovision winner Running Scared. She finished in fourth place.
Germany's Roman Lob performed Standing Still, a song co-written by Britain's Jamie Cullum. He finished in a respectable eighth place, with 110 points. Last year's host nation previously won in 2010, with Satellite, by Lena.
BBC One Eurovision host Graham Norton likened Nina Zilli to an "Italian Amy Winehouse" as she performed her song L'Amore E Femmina (Out of Love). Italy only returned to the contest last year after a 14-year absence. Zilli was among the favourites, but only just scraped into the top 10.
Iranian-born Tooji, who performed Norway's entry Stay, had the misfortune of taking last place out of the 26 competing countries. His seven points kept Britain out of unenviable bottom slot.
It was not to be 'The Hump's' night, despite having a gift from Elvis on his person as a so-called good luck charm. The legendary Release Me singer opened the contest with aplomb, but was disregarded by voters, notching up a mere 12 points. He called Eurovision a "wonderful experience".
