On 28 June 1919, the Treaty of Versailles was signed. Here is a short film to mark that centenary, made by Ronan McGreevy of the Irish Times, along with Professor Alan Kramer, Professor Margaret MacMillan and Dr John Gibney. Ronan spoke at last year's West Cork History Festival when he screened his brilliant film United Ireland: how Nationalists and Unionists fought together in Flanders.
[Interesting aside: MacMillan is the great-grand-daughter of David Lloyd-George, British Prime Minister in the final years of the First World War, and during the negotiations at Versailles.]
