Indo-Greek Kingdom in the context of "Pushkalavati"

In classical antiquity, the Hellenistic period covers the time in Greek, Eastern Mediterranean, and West Asian (or Middle Eastern) history following Classical Greece, between the death of Alexander the Great in 323 BC and the death of Cleopatra VII in 30 BC, in which these regions were under the influence of Greek leadership, culture, and language. The Hellenistic period was followed by the ascendancy of the Roman Empire, the Battle of Actium in 31 BC, and the Roman conquest of Ptolemaic Egypt the following year, which eliminated the last major Hellenistic kingdom. Its name stems from the Ancient Greek word Hellas (Ἑλλάς, Hellás), which was gradually recognized as the name for Greece, from which the modern historiographical term Hellenistic was derived. The term "Hellenistic" is to be distinguished from "Hellenic" in that the latter refers to Greece itself, while the former encompasses all the ancient territories of the period that had come under significant Greek influence, particularly the Hellenized Ancient Near East, after the conquests of Alexander the Great.

After the Macedonian conquest of the Achaemenid Empire in 330 BC and its disintegration shortly thereafter in the Partition of Babylon and subsequent Wars of the Diadochi, Hellenistic kingdoms were established throughout West Asia (Seleucid Empire, Kingdom of Pergamon), Northeast Africa (Ptolemaic Kingdom) and South Asia (Greco-Bactrian Kingdom, Indo-Greek Kingdom). This resulted in an influx of Greek colonists and the export of Greek culture and language to these new realms, a breadth spanning as far as modern-day India. These new Greek kingdoms were also influenced by regional indigenous cultures, adopting local practices which were deemed beneficial, necessary, or convenient. Hellenistic culture thus represents a fusion of the ancient Greek world with that of the Western Asian, Northeastern African, and Southwestern Asian worlds. The consequence of this mixture gave rise to a common Attic-based Greek dialect, known as Koine Greek, which became the lingua franca throughout the ancient world.

The Greco-Bactrian Kingdom (Greek: Βασιλεία τῆς Βακτριανῆς, romanized: Basileía tês Baktrianês, lit. 'Kingdom of Bactria') was a Greek kingdom during the Hellenistic period located in Central Asia and Afghanistan. The kingdom was founded by the Seleucid satrap Diodotus I Soter in about 256 BC, and continued to dominate Central Asia until its fall around 120 BC. At its peak the kingdom consisted of present-day Afghanistan, Tajikistan, Uzbekistan and Turkmenistan, and for a short time, small parts of Kazakhstan, Pakistan, India and Iran. An extension further east, with military campaigns and settlements, may have reached the borders of the Qin State in China by about 230 BC.

A Greek population was already present in Bactria by the 5th century BC. Alexander the Great had conquered the region by 327 BC, founding many cities, most of them named Alexandria, and further settling Macedonians and other Greeks. After the death of Alexander, control of Bactria passed on to his general Seleucus I Nicator. The fertility and the prosperity of the region led to the creation of the Greco-Bactrian kingdom under Diodotus by the early 3rd century BC, as a successor state of the Seleucid Empire. The Bactrian Greeks grew increasingly more powerful and invaded north-western India between 190 and 180 BC under king Demetrius, the son of Euthydemus. This invasion led to the creation of the Indo-Greek kingdom, which in turn was a successor to the Greco-Bactrian kingdom, and was subsequently ruled by the kings Pantaleon and Apollodotus I. Historical records indicate that many rich and prosperous cities were present in the kingdom, but only a few of them have been excavated, such as Ai-Khanoum and Bactra. The city of Ai-Khanoum, in north-eastern Afghanistan, had all the hallmarks of a true Hellenistic city with a Greek theater, gymnasium and some houses with colonnaded courtyards.

Demetrius I Anicetus (Ancient Greek: Δημήτριος Ἀνίκητος, romanized: Dēmḗtrios Aníkētos, "Demetrius the Unconquered"), also called Dimetriya in Indian sources, was a Greco-Bactrian king and the founder of the Indo-Greek kingdom, who ruled areas from Bactria to ancient northwestern India. He was the son of the Greco-Bactrian ruler Euthydemus I and succeeded him around 200 BC, after which he conquered extensive areas in what is now southern Afghanistan, Pakistan and northwestern India.

He was never defeated in battle and was posthumously referred to as "the Unconquered" (Ἀνίκητος, Aniketos) on the pedigree coins of his successor Agathocles of Bactria. Demetrius I may have been the initiator of the Yavana era, starting in 186–185 BC, which was used for several centuries thereafter.

Taxila (Punjabi: ٹيکسلا, romanized: Ṭeksilā), historically known as Takshashila, is a city and UNESCO World Heritage Site on the Pothohar Plateau of Punjab, Pakistan. Founded around c. 1000 BC, it is one of the oldest cities in South Asia. Taxila is located within the Taxila Tehsil of Rawalpindi District in northern Punjab, and it lies approximately 25 kilometres (16 mi) northwest of the Islamabad–Rawalpindi metropolitan area and is just south of the Haripur District of Khyber Pakhtunkhwa.

Established during the Vedic period, Old Taxila was for a time the capital city of ancient Gandhāra. Situated on the eastern shore of the Indus River—the pivotal junction of the Indian subcontinent and Central Asia—it was possibly founded around 1000 BCE. Takshashila and Pushkalavati remained prominent cities in Gandhāra during the Mahajanapadas. The city is believed to have become part of the Achaemenid Empire during 550 – 326 BCE. In 326 BCE, it was claimed by Alexander the Great, after overthrowing the Achaemenids. Alexander gained control of the city without a battle since it immediately surrendered to his Macedonian Empire. This was followed successively by the Mauryans (~317 – ~200 BCE), the Indo-Greeks (~200 BCE – ~55 BCE), the Indo-Scythians (~80 BCE – ~30 CE), and the Kushan Empire (~30 CE – ~375 CE), who destroyed the existing city, in the first century CE, to build their own on a site to the north of the ruins. Owing to its strategic location, Taxila has changed hands many times over the centuries, with many polities vying for its control. When the great ancient trade routes connecting these regions ceased to be important, the city sank into insignificance and was finally destroyed in the 5th century by the invading Hunas. In mid-19th century British India, ancient Taxila's ruins were rediscovered by British archaeologist Alexander Cunningham and extensively excavated by Sir John Marshall. In 1980, UNESCO designated Taxila as a World Heritage Site. The area was part of the ancient Gandhara region. Taxila (ancient city) was designated a UNESCO World Heritage Site in 1980 and is located in the town of Taxila.
