Paropamisadae in the context of "Gandāra"

Theophilus Dicaeus (Ancient Greek: Θεόφιλος Δίκαιος, romanized: Theophilos Dikaios) was a minor Indo-Greek king who ruled for a short time in the Paropamisadae. He was possibly a relative of Zoilus I and is only known from coins. It is possible that some of Theophilus' coins in fact belong to another ruler, in Greek Bactria, during approximately the same period.

The Baba Mountain range (Pashto: بابا غر Bâbâ Ǧar; Persian: کوه بابا Kōh-i Bābā; or Kūh-e Bābā; Kōh or Kūh meaning ′mountain′, Bābā meaning ′father′) is the western extension of the Hindu Kush, and the origin of Afghanistan's Kabul, Arghandab, Helmand, Farah, Hari, Murghab, Balkh, and Kunduz rivers. The mountain range is crowned by Foladi peak (or Shah Fuladi) rising 5048 m (some old maps and dictionaries: 5143 m) above sea level, and is located south of Bamyan.

The Koh-e Firoz plateau merges farther to the west by gentle gradients into the Paropamise, and which may be traced across the Hari River to Mashad. To the southwest of the culminating peaks, long spurs divide the upper tributaries of the Helmand River, and separate its basin from that of the Farah River. These spurs retain a considerable altitude, marked by peaks exceeding 11,000 ft (3,400 m). They sweep in a broad band of roughly parallel ranges to the southwest, preserving their general direction till they abut on the Great Registan desert to the west of Kandahar, where they terminate in a series of detached and broken anticlinals whose sides are swept by a sea of encroaching sand. The long, straight, level-backed ridges which divide the Argandab, the Tarnak and Arghastan valleys, flank the route from Kandahar to Ghazni.The high jagged peaks above the Hajigak Pass, blue-black and shining, shimmer in the sunlight for they contain an estimated reserve of 2 billion tons of iron ore; Asia's richest deposit. The very steep descent from the Hajigak Pass (3,700 m (12,100 ft)) with its numerous hairpin bends leads to the sparkling Kalu River, known locally as the Sauzao or Green Waters. It is bordered by poplars and several charming villages.

The Alchon Huns, (Bactrian: αλχον(ν)ο Alkhon(n)o or αλχαν(ν)ο Alkhan(n)o) also known as the Alkhan, Alchono, Alxon, Alkhon, Alakhana, and Walxon, were a nomadic people who established states in Central Asia and the Indian subcontinent during the 4th and 6th centuries CE. They were first mentioned as being located in Paropamisus, and later expanded south-east, into the Punjab and Central India, going as far as Eran and Kausambi. The Alchon invasion of the Indian subcontinent eradicated the Kidarite Huns who had preceded them by about a century, and contributed to the fall of the Gupta Empire, in a sense bringing an end to Classical India.

The invasion of India by the Huna peoples follows invasions of the subcontinent in the preceding centuries by the Yavana (Indo-Greeks), the Saka (Indo-Scythians), the Pahlava (Indo-Parthians), and the Kushana (Yuezhi). The Alchon Empire was the second of four major Huna states established in Central Asia and the Indian subcontinent. The Alchon were preceded by the Kidarites and succeeded by the Hephthalites and Nezak Huns in Bactria and the Hindu Kush respectively. The names of the Alchon kings are known from their extensive coinage, Buddhist accounts, and a number of commemorative inscriptions throughout the Indian subcontinent.

Alexandria in the Caucasus (Ancient Greek: Ἀλεξάνδρεια Alexándreia; medieval Kapisa, modern Bagram) was a colony of Alexander the Great. It was 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", specifically as "Caucasus Indicus" (Ancient Greek: Καύκασος Ινδικός) in parallel to their Western equivalent, the Caucasus Mountains between Europe and Asia.
