Alexandria in the Caucasus (Ἀλεξάνδρεια) (medieval Kapisa, modern Bagram) was a colony of Alexander the Great (one of many colonies designated with the name Alexandria). He founded the colony at an important junction of communications in the southern foothills of the Hindu Kush mountains, in the country of the Paropamisadae. In Classical times, the Hindu Kush mountains were also designated as the "Caucasus" in parallel to their Western equivalent, the Caucasus Mountains between Europe and Asia. Alexander populated the city with 7,000 Macedonians, 3,000 mercenaries and thousands of natives (according to Curtius VII.3.23), or some 7,000 natives and 3,000 non-military camp followers and a number of Greek mercenaries (Diodorus, XVII.83.2), in March 329 BC. He had also built forts in what is now Bagram, Afghanistan, at the foot of the Hindu Kush, replacing forts erected in much the same place by Persia's king Cyrus the Great c. 500 BC, Alexandria being in fact a refoundation of an Achaemenid settlement called Kapisa. The deity of the city seems to have been Zeus, as suggested by coins of the Greco-Bactrian king Eucratides. Alexandria of the Caucasus was one of the capitals of the Indo-Greek kings (180 BC – AD 10). During the reign of Menander I the city was recorded as having a thriving Buddhist community, headed by Greek monks. The epic Sri Lankan poem Mahāvaṃsa mentions the Greek (Pali: Yona, lit: "Ionian") Buddhist monk Mahadhammarakkhita (Mahadharmaraksita), who is said to have come from “Alasandra” (thought to be Alexandria of the Caucasus), with 30,000 monks for the foundation ceremony of the Maha Thupa at Anuradhapura in Sri Lanka: From Alasanda the city of the Yonas came the thera (elder) Yona Mahadhammarakkhita with thirty thousand bhikkhus. Some archaeological evidence concerning Alexandria of the Caucasus was gathered by Charles Masson (1800–1853), providing insight into the history of that lost city. His findings include coins, rings, seals and other small objects.
