Jazz artist was already a household name in Ukraine, before winning the nomination to represent her country at Eurovision
The first ever Crimean Tatar to perform at the contest, she will appear in Thursday's second semi-final in Stockholm.
And her song, about Stalin, Crimea and claims of ethnic cleansing, is a far cry from the typical Eurovision song.
Jamala's Eurovision entry, 1944, is about the mass deportation during World War Two of the entire ethnic Tatar population from Crimea by Soviet troops under the orders of Stalin.
It is also "very personal". Jamala's great-grandmother and her five children were among a quarter of a million Tatars who were packed on trains "like animals".
However historical and personal the song purports to be, anything linked to Crimea is an emotive topic in Ukraine today.
The eastern peninsula is now firmly under Russian control, since the territory was annexed by President Vladimir Putin in March 2014.
The West condemns the annexation as illegal. Ukraine still considers Crimea to be part of its territory.
