In 377 B.C., the city of Halicarnassus was the capitol of a small kingdom along the Mediterranean coast of Asia Minor. It was in that year the ruler of this land, Hecatomnus of Mylasa, died and left control of the kingdom to his son, Mausolus. Hecatomnus, a local satrap to the Persians, had been ambitious and had taken control of several of the neighboring cities and districts. Then Mausolus during his reign extended the territory even further so that it eventually included most of southwestern Asia Minor.
