Performing during the show in position 11, "Euphoria" was announced among the top 10 entries of the second semi-final and therefore qualified to compete in the final on 26 May.
In the final, Sweden performed in position 17 and placed first out of the 26 participating countries, winning the contest with 372 points.
Following the introduction of semi-finals for the 2004, Sweden's entries, to this point, have featured in every final except for 2010 when the nation failed to qualify.
Since 1959, SVT has organised the annual competition Melodifestivalen in order to select the Swedish entry for the Eurovision Song Contest.
Melodifestivalen 2012 was the Swedish music competition that selected Sweden's entry for the Eurovision Song Contest 2012.
The combination of points from a viewer vote and eleven international jury groups determined the winner.
The nations that comprised the international jury were Belgium, Bosnia and Herzegovina, Cyprus, Estonia, France, Germany, Ireland, Malta, Norway, Ukraine and the United Kingdom.
The Swedish entry received votes from 40 countries and won the contest, with only Italy failing to award them any points.
