Sixth-formers from three Sheffield schools did battle in a debating contest to decide the question: Who was the greatest Briton of the 20th century?
The judges awarded the £50 first prize to Sam Oliver from Birkdale School after deciding that he made the most compelling case on behalf of Margaret Thatcher.
The event was organised by the Sheffield branch of the Historical Association at the Humanities Research Institute in Gell Street, close to the city centre.
Also taking part were students from High Storrs and Dronfield Henry Fanshawe schools – Roisin Henry, Caitlin Pollard, Adam Colbert and Zach Smith.
Other heroes included in the debate were Clement Atlee, Aneurin Bevan, Winston Churchill and Alexander Fleming.
An association spokeswoman said: “The judges had a long debate on which of the students was most persuasive as the standard of the entries was so high.
“Family and friends came to support the students and the whole event was enjoyed by everyone.”
