Following Alexander the Great’s conquest of Persia in the 330s BC, Baalbek (under its Hellenic name Heliopolis) formed part of the Diadochi kingdoms of Egypt & Syria. It was annexed by the Romans during their eastern wars. The settlers of the Roman colony Colonia Julia Augusta Felix Heliopolitana may have arrived as early as the time of Caesar but were more probably the veterans of the 5th and 8th Legions under Augustus, during which time it hosted a Roman garrison.
