Roman Emperor Trajan led two great wars against the people of Dacia. No written documentation of this campaign survives, but its story is depicted in stone on Trajan's Column, a monument that has towered above Rome for almost 2,000 years. Starting here, the film retraces the steps of Trajan's army and the course of the wars, and uncovers the military secrets of an empire founded on war. 4/6.
