Gedrosia: part of the ancient Achaemenid empire, modern Balûchestân in Iran.
The country was probably conquered by the Persian king Cyrus the Great (559-530 BCE), although information about his campaign is comparatively late. The capital of Gedrosia was Pura, which is probably identical to modern Bampûr, forty kilometers west of Irânshahr.
Gedrosia became famous in Europe when the Macedonian king Alexander the Great tried to cross the Gedrosian desert and lost many men (325) (text).
Several scholars have argued that the Persian satrapy Maka is identical to Gedrosia (which is a Greek name). One argument is the similarity of the name Maka to the modern name Makran, a part of Pakistan that is situated a bit more to the east. However, it is more likely that Maka is to be sought in modern Oman, which was called Maketa in Antiquity.
