Gnaeus Pompeius Magnus earned his "the Great" in many, many respects. He was a great general, an outstanding administrator, a compassionate man, a loving husband and father, and a loyal friend. However he happened to be a contemporary of somebody who was smarter, less scrupulous, and very ambitious: Caesar. They were for many years close friends; Pompey was even married to Caesar's daughter Julia. But the death of Julia took the last restraint off, and Caesar's ambition to rule Rome dragged the relationship into deadly enmity.
