Students of early Indian history are aware that the Yuga-purāṇa section of the Gārgī-saṁhitā contains an account of the Yavanas or Indo-Bactrian Greeks, important because it speaks of a Yavana invasion of Puṣpapura (i.e. the city of Pāṭaliputra, the capital of the Mauryas) and some other areas apparently forming parts of the Maurya empire, and assigns it to a date shortly after Śāliūka who was a descendant of Aśoka and flourished about 200 b.c. So the Yavanas invaded Pāṭaliputra not long before the Brāhmaṇa general Puṣyamitra killed his master, the last Maurya king Bṛhadratha, and occupied the Maurya throne about 185 b.c. There can be little doubt that the success of the Greeks against the Mauryas is associated with the dynastic revolution, and that the rise of Puṣyamitra was due to the Greek occupation of Maurya territories.
