Hellenistic period

In classical antiquity, the Hellenistic period covers the time in Greek and Mediterranean history after Classical Greece, between the death of Alexander the Great in 323 BC and the death of Cleopatra VII in 30 BC, which was followed by the ascendancy of the Roman Empire, as signified by 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 where 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.

During the Hellenistic period, Greek cultural influence reached its peak in the Mediterranean and beyond. Prosperity and progress in the arts, literature, theatre, architecture, music, mathematics, philosophy, and science characterize the era. The Hellenistic period saw the rise of New Comedy, Alexandrian poetry, translation efforts such as the Septuagint, and the philosophies of Stoicism, Epicureanism, and Pyrrhonism. In science, the works of the mathematician Euclid and the polymath Archimedes are exemplary. Sculpture during this period was characterized by intense emotion and dynamic movement, as seen in sculptural works like the Dying Gaul and the Venus de Milo. A form of Hellenistic architecture arose which especially emphasized the building of grand monuments and ornate decorations, as exemplified by structures such as the Pergamon Altar. The religious sphere of Greek religion expanded through syncretic facets to include new gods such as the Greco-Egyptian Serapis, eastern deities such as Attis and Cybele, and a syncretism between Hellenistic culture and Buddhism in Bactria and Northwest India.

Scholars and historians are divided as to which event signals the end of the Hellenistic era. There is a wide chronological range of proposed dates that have included the final conquest of the Greek heartlands by the expansionist Roman Republic in 146 BC following the Achaean War, the final defeat of the Ptolemaic Kingdom at the Battle of Actium in 31 BC, the end of the reign of the Roman emperor Hadrian in AD 138, and the move by the emperor Constantine the Great of the capital of the Roman Empire to Constantinople in AD 330. Though this scope of suggested dates demonstrates a range of academic opinion, a generally accepted date by most of scholarship has been that of 31/30 BC.

The word originated from Ancient Greek Ἑλληνιστής (Hellēnistḗs, "one who uses the Greek language"), from Ἑλλάς (Hellás, "Greece"); as if "Hellenist" + "ic".

The idea of a Hellenistic period is a 19th-century concept, and did not exist in ancient Greece. Although words related in form or meaning, e.g. Hellenist (Ancient Greek: Ἑλληνιστής, Hellēnistēs), have been attested since ancient times, it has been attributed to the 19th-century German historian Johann Gustav Droysen, who in his classic work Geschichte des Hellenismus (History of Hellenism), coined the term Hellenistic to refer to and define the period when Greek culture spread in the non-Greek world after Alexander's conquest. Following Droysen, Hellenistic and related terms, e.g. Hellenism, have been widely used in various contexts; a notable such use is in Culture and Anarchy by Matthew Arnold, where Hellenism is used in contrast with Hebraism.

The major issue with the term Hellenistic lies in its convenience, as the spread of Greek culture was not the generalized phenomenon that the term implies. Some areas of the conquered world were more affected by Greek influences than others. The term Hellenistic also implies that the Greek populations were of majority in the areas in which they settled, but in many cases, the Greek settlers were actually the minority among the native populations. The Greek population and the native population did not always mix; the Greeks moved and brought their own culture, but interaction did not always occur.^{[citation needed]}

While a few fragments exist, there are no complete surviving historical works that date to the hundred years following Alexander's death. The works of the major Hellenistic historians Hieronymus of Cardia (who worked under Alexander, Antigonus I and other successors), Duris of Samos and Phylarchus, which were used by surviving sources, are all lost. The earliest and most credible surviving source for the Hellenistic period is Polybius of Megalopolis (c. 200–118), a statesman of the Achaean League until 168 BC when he was forced to go to Rome as a hostage. His Histories eventually grew to a length of forty books, covering the years 220 to 167 BC.
