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.

French (français [fʁɑ̃sɛ] or langue française [lɑ̃ɡ fʁɑ̃sɛːz] ) is a Romance language of the Indo-European family. Like all other Romance languages, it descended from the Vulgar Latin of the Roman Empire. French evolved from Northern Old Gallo-Romance, a descendant of the Latin spoken in Northern Gaul. Its closest relatives are the other langues d'oïl—languages historically spoken in northern France and in southern Belgium, which French (Francien) largely supplanted. It was also influenced by native Celtic languages of Northern Roman Gaul and by the Germanic Frankish language of the post-Roman Frankish invaders. As a result of French and Belgian colonialism from the 16th century onward, it was introduced to new territories in the Americas, Africa, and Asia, and numerous French-based creole languages, most notably Haitian Creole, were developed. A French-speaking person or nation may be referred to as Francophone in both English and French.

French is an official language in 26 countries, as well as one of the most geographically widespread languages in the world, with speakers in about 50 countries. Most of these countries are members of the Organisation internationale de la Francophonie (OIF), the community of 54 member states which share the use or teaching of French. It is estimated to have about 310 million speakers, of which about 74 million are native speakers; it is spoken as a first language (in descending order of the number of speakers) in France, Canada (Quebec), Belgium (Wallonia and the Brussels-Capital Region), western Switzerland (Romandy region), parts of Luxembourg, and Monaco. Meanwhile in Francophone Africa it is spoken mainly as a second language or lingua franca, though it has also become a native language in a small number of urban areas; in some North African countries like Algeria, despite not having official status, it is also a first language among some upper classes of the population alongside the indigenous ones, but only a second one among the general population.

The Celts (/kɛlts/ KELTS, see pronunciation for different usages) or Celtic peoples (/ˈkɛltɪk/ KEL-tik) were a collection of Indo-European peoples in Europe and Anatolia, identified by their use of Celtic languages and other cultural similarities. Major Celtic groups included the Gauls; the Celtiberians and Gallaeci of Iberia; the Britons, Picts, and Gaels of Britain and Ireland; the Boii; and the Galatians. The interrelationships of ethnicity, language and culture in the Celtic world are unclear and debated; for example over the ways in which the Iron Age people of Britain and Ireland should be called Celts. In current scholarship, 'Celt' primarily refers to 'speakers of Celtic languages' rather than to a single ethnic group.

The history of pre-Celtic Europe and Celtic origins is debated. The traditional "Celtic from the East" theory, says the proto-Celtic language arose in the late Bronze Age Urnfield culture of central Europe, named after grave sites in southern Germany, which flourished from around 1200 BC. This theory links the Celts with the Iron Age Hallstatt culture which followed it (c. 1200–500 BC), named for the rich grave finds in Hallstatt, Austria, and with the following La Tène culture (c. 450 BC onward), named after the La Tène site in Switzerland. It proposes that Celtic culture spread westward and southward from these areas by diffusion or migration. A newer theory, "Celtic from the West", suggests proto-Celtic arose earlier, was a lingua franca in the Atlantic Bronze Age coastal zone, and spread eastward. Another newer theory, "Celtic from the Centre", suggests proto-Celtic arose between these two zones, in Bronze Age Gaul, then spread in various directions. After the Celtic settlement of Southeast Europe in the 3rd century BC, Celtic culture reached as far east as central Anatolia, Turkey.

The Macedonians (Ancient Greek: Μακεδόνες, Makedónes) were an ancient tribe that lived on the alluvial plain around the rivers Haliacmon and lower Axios in the northeastern part of mainland Greece. Essentially an ancient Greek people, they gradually expanded from their homeland along the Haliacmon valley on the northern edge of the Greek world, absorbing or driving out neighbouring non-Greek tribes, primarily Thracian and Illyrian. They spoke Ancient Macedonian, which is usually classified by scholars as a dialect of Northwest Doric Greek, and occasionally as a distinct sister language of Greek or an Aeolic Greek dialect. However, the prestige language of Macedon during the Classical era was Attic Greek, replaced by Koine Greek during the Hellenistic era. Their religious beliefs mirrored those of other Greeks, following the main deities of the Greek pantheon, although the Macedonians continued Archaic burial practices that had ceased in other parts of Greece after the 6th century BC. Aside from the monarchy, the core of Macedonian society was its nobility. Similar to the aristocracy of neighboring Thessaly, their wealth was largely built on herding horses and cattle.

Although composed of various clans, the kingdom of Macedonia, established around the 7th century BC, is mostly associated with the Argead dynasty and the tribe named after it. The dynasty, also known as the Temenid dynasty, was allegedly founded by Perdiccas I, descendant of the legendary Temenus of Argos, while the region of Macedon derived its name from Makedon, a figure of Greek mythology. Traditionally ruled by independent families, the Macedonians seem to have accepted Argead rule by the time of Alexander I (r. 498 – 454 BC). Under Philip II (r. 359 – 336 BC), the Macedonians are credited with numerous military innovations, which enlarged their territory and increased their control over other areas extending into Thrace. This consolidation of territory allowed for the exploits of Alexander the Great (r. 336 – 323 BC), the conquest of the Achaemenid Empire, the establishment of the diadochi successor states, and the inauguration of the Hellenistic period in West Asia, Greece, and the broader Mediterranean world. The Macedonians were eventually conquered by the Roman Republic, which dismantled the Macedonian monarchy at the end of the Third Macedonian War (171–168 BC) and established the Roman province of Macedonia after the Fourth Macedonian War (150–148 BC).

The Middle East, or the Near East, was one of the cradles of civilization: after the Neolithic Revolution and the adoption of agriculture, many of the world's oldest cultures and civilizations were created there. Since ancient times, the Middle East has had several lingua franca: Akkadian, Hebrew, Aramaic, Greek, and Arabic. The Sumerians, around the 5th millennium BC, were among the first to develop a civilization. By 3150 BC, Egyptian civilization unified under its first pharaoh. Mesopotamia hosted powerful empires, notably Assyria which lasted for 1,500 years. For centuries after the 7th century BC, the region was dominated by Persian powers like the Achaemenid Empire.

In the 1st century BC, the Roman Republic conquered most of the region, and its successor, the Roman Empire, that ruled from the 6th to 15th centuries AD referred to as the Byzantine Empire, grew significantly more. Roman pagan religions were replaced by Christianity in the 4th century AD. From the 3rd to 7th centuries, Rome ruled alongside the Sasanian Empire. From the 7th century, Islam spread rapidly, expanding Arab identity in the region. The Seljuk dynasty displaced Arab dominance in the 11th century, followed by the Mongol Empire in the 13th century.

Koine Greek (ἡ κοινὴ διάλεκτος, hē koinḕ diálektos, lit. 'the common dialect'), also variously known as Hellenistic Greek, common Attic, the Alexandrian dialect, Biblical Greek, Septuagint Greek or New Testament Greek, was the common supra-regional form of Greek spoken and written during the Hellenistic period, the Roman Empire, and the early Byzantine Empire. It evolved from the spread of Greek following the conquests of Alexander the Great in the fourth century BC, and served as the lingua franca of much of the Mediterranean region and the Middle East during the following centuries. It was based mainly on Attic and related Ionic speech forms, with various admixtures brought about through dialect levelling with other varieties.

Koine Greek included styles ranging from conservative literary forms to the spoken vernaculars of the time. As the dominant language of the Byzantine Empire, it developed further into Medieval Greek, which then turned into Modern Greek.
