Death of Alexander the Great in the context of "Hellenistic age"

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 Ptolemaic Kingdom (/ˌtɒlɪˈmeɪ.ɪk/; Koine Greek: Πτολεμαϊκὴ βασιλεία, Ptolemaïkḕ basileía) or Ptolemaic Empire was an ancient Greek polity based in Egypt during the Hellenistic period. It was founded in 305 BC by the Macedonian Greek general Ptolemy I Soter, a companion of Alexander the Great, and ruled by the Ptolemaic dynasty until the death of Cleopatra VII in 30 BC. Reigning for nearly three centuries, the Ptolemies were the longest and final dynasty of ancient Egypt, heralding a distinct era of religious and cultural syncretism between Greek and Egyptian culture.

Alexander the Great conquered Egypt in 332 BC during his campaigns against the Achaemenid Empire. Alexander's death in 323 BC was followed by the rapid unraveling of the Macedonian Empire amid competing claims by the diadochi, his closest friends and companions. Ptolemy, one of Alexander's most trusted generals and confidants, won control of Egypt from his rivals and declared himself its ruler in 305 BC. Alexandria, a Greek polis founded by Alexander, became the capital city and a major center of Greek culture, learning, and trade for the next several centuries. Following the Syrian Wars with the Seleucid Empire, a rival Hellenistic state, the Ptolemaic Kingdom expanded its territory to include eastern Libya, the Sinai, and northern Nubia.

The wars of Alexander the Great were a series of conquests and military campaigns carried out by Alexander III of Macedon from 336 to 323 BC. They began with his conquest of the Achaemenid Empire, which was ruled by Darius III. After a series of victories over the Persians and the defeat Darius, he began a campaign against local chieftains and warlords that stretched from Greece to as far as the Indus Valley. At the time of his death, Alexander ruled over most regions of Greece and the conquered Achaemenid Empire, including much of Achaemenid Egypt.

Despite his military accomplishments, Alexander did not establish a stable empire, and his untimely death threw the vast territories he conquered into a series of civil wars known as the Wars of the Diadochi.

Antipater (/ænˈtɪpətər/; Ancient Greek: Ἀντίπατρος, romanized: Antipatros, lit. 'like the father'; c. 400 BC – 319 BC) was a Macedonian general, regent and statesman under the successive kingships of Philip II of Macedon and his son, Alexander the Great. In the wake of the collapse of the Argead house, his son Cassander eventually ruled Macedonia as a king in his own right.

Probably active during the reign of Perdiccas III of Macedon, most of Antipater's political career was as one of Philip II's foremost Hetairoi. After Philip II's death, he helped Alexander secure the throne. When Alexander began his wars against the Persian Empire in 336 BC, Antipater remained behind to hold Macedon and Greece as regent. While Alexander was campaigning, Antipater crushed revolts, like that of King Agis III of Sparta, and managed Greek affairs. After the Death of Alexander the Great in 323 BC, Antipater was reconfirmed in his position as viceroy of Europe in the Partition of Babylon.
