Alexander required service from his citizins
in his army as soldiers. Unlike the traditional citizen-soldier who
had to spend most of the year working or who enjoyed independent wealth, Alexanders
professional soldiers could stay in the field year round and recieve payment.
Alexander payed the soldiers in food for the soldiers and camp followers
in return for their service.
Alexander's army was not prejudice and gratefully received soldiers of
different nationalities. When Alexander married a Persian princess he encouraged
his soldiers to marry Persian women also. Many of them did just as their
powerful leader commanded.
