He had his capital at Sakala in the Punjab (present-day Sialkot).The expression "Indo-Greek Kingdom" loosely describes a number of various dynastic polities, traditionally associated with a number of regional capitals like Taxila, Other potential centers are only hinted at; for instance, Ptolemy's Geographia and the nomenclature of later kings suggest that a certain Theophila in the south of the Indo-Greek sphere of influence may also have been a satrapal or royal seat at one time.He (Antiochus) crossed the Caucasus (the Caucasus Indicus or Paropamisus: mod.

Some Greeks (Yavanas) may have played an administrative role in the territories ruled by Ashoka: the Junagadh rock inscription of Rudradaman records that during the rule of Ashoka, a Yavana King/ Governor named Tushaspha was in charge in the area of Girnar, Gujarat, mentioning his role in the construction of a water reservoir.
When the ruler of neighbouring Parthia, the former satrap and self-proclaimed king Andragoras, was eliminated by Arsaces, the rise of the Parthian Empire cut off the Greco-Bactrians from direct contact with the Greek world.
Overland trade continued at a reduced rate, while sea trade between Greek Egypt and Bactria developed.
Diodotus was succeeded by his son Diodotus II, who allied himself with the Parthian Arsaces in his fight against Seleucus II: Soon after, relieved by the death of Diodotus, Arsaces made peace and concluded an alliance with his son, also by the name of Diodotus; some time later he fought against Seleucos who came to punish the rebels, and he prevailed: the Parthians celebrated this day as the one that marked the beginning of their freedom and possibly satrap of Sogdiana, overthrew Diodotus II around 230 BC and started his own dynasty.

but since the extensive sources available on Seleucus never mention an Indian princess, it is thought that the marital alliance went the other way, with Chandragupta himself or his son Bindusara marrying a Seleucid princess, in accordance with contemporary Greek practices to form dynastic alliances. From him, Vindusara was born and ruled for the same number of years as his father.
An Indian Puranic source, the Pratisarga Parva of the Bhavishya Purana, described the marriage of Chandragupta with a Greek ("Yavana") princess, daughter of Seleucus, "Chandragupta married with a daughter of Suluva, the Yavana king of Pausasa. His son was Ashoka." On these occasions, Greek populations apparently remained in the northwest of the Indian subcontinent under Mauryan rule.
