The motion was passed with 19 'yes' votes against 5 'no' votes.
In 1302 a trial stated that Dante, the author of "The Divine Comedy," would be executed if he stepped foot in Florence again. He spent the last 20 years of his life in various Italian cities, and finally ended his days in Ravenna in 1321.
The city authorities hope the vote was "a decisive step" toward Dante's full rehabilitation.
Dante was exiled from Florence after backing the 'wrong' political faction.
