The Indo-Greek Kingdom (or sometimes Graeco-Indian Kingdom) covered various parts of the northwest and northern
Indian subcontinent from 180 BCE to around 10 CE, and was ruled by a succession of more than thirty
Hellenic and
Hellenistic kings, often in conflict with each other. The kingdom was founded when the
Greco-Bactrian king
Demetrius invaded India in 180 BCE, ultimately creating an entity which seceded from the powerful
Greco-Bactrian Kingdom centered in Bactria (today's northern
Afghanistan). Since the term "Indo-Greek Kingdom" loosely describes a number of various dynastic polities, it had numerous cities, such as
Taxila in the easternmost part of the Pakistani
Punjab, or
Pushkalavati and
Sagala. These cities would house a number of dynasties in their times, and based on
Ptolemy's
Geographia and the nomenclature of later kings, a certain Theophila in the south was also probably a satrapal or royal seat at some point.
