Featuring specially commissioned artwork and maps, carefully chosen illustrations and insightful analysis, this book examines the legendary Mongol warriors and their vastly different European opponents. Having conquered much of Central Asia by 1237, the Mongols advanced into the northern Caucasus. The fall of several key centres such as Riazan and Vladimir was followed by Mongol victory at Kiev. Moving west, in 1241 two Mongol armies achieved stunning victories at the battles of Liegnitz in Poland and the Sajo River (Mohi) in Hungary, before suffering their only reverse of the campaign at the fortress of Klis. The Mongol forces regrouped in Hungary to prepare for a further advance into Austria and Germany, but the death of their leader, Ogedei Khan, meant that his generals were required to return to Mongolia to choose a successor. Smaller Mongol forces would return to raid in the years to come, but never again would Western Europe be threatened as it was in 1242.
