Bactrian language
Afghanistan in 305 BC when the Greek Seleucid Empire made an alliance with the Indian Maurya Empire. The resulting Greco-Buddhism flourished under the Greco-Bactrian Kingdom (250 BC-125 BC) and the later Indo-Greek Kingdom (180 BC - 10 AD) in northern Afghanistan. Greco-Buddhism reached its height under the Kushan Empire, which used the Greek alphabet to write its Bactrian language.
