Dublin-born artist Duncan Campbell has won this year's Turner Prize for his series of films called 'It For Others'.
The judges said Mr Campbell's work, which takes in African art and iconic images from the Troubles in Northern Ireland, was "topical and compelling".
His hour-long essay film was part of Scotland's entry to last year's Venice Biennale.
The film artist, who is based in Glasgow, was the firm favourite to win as soon as the shortlist was announced.
Campbell, known for weaving together old archival footage, YouTube clips and censored erotic images, described the work as being "about how you can understand certain histories through objects".
Accepting his prize, the 42-year-old said: "This money will make a huge difference to me, even being nominated for the prize has given me great heart."
'12 Years A Slave' actor Chiwetel Ejiofor presented the £25,000 (€31,500) prize to Mr Campbell at a ceremony at Tate Britain in central London.
In a statement this evening, the Arts Council congratulated Campbell on his win.
Its chair, Sheila Pratschke, said: "Duncan's work often tackles difficult and challenging issues relating power and politics to different structures and contexts.
"We are exceptionally proud that an Irish artist has received this internationally renowned prize and it reflects the impact that Irish artists continue to make on a world stage."
The Turner Prize, a prestigious art award in the UK, has a reputation for controversy.
Previous winners have included Martin Creed's installation featuring a light going on and off and Grayson Perry's pots tackling subjects such as death and child abuse.
