Polybius in the context of "Classical republic"

The Ardiaei were an Illyrian people who resided in the territory of present-day Bosnia and Herzegovina, Albania, Kosovo, Montenegro, and Croatia between the Adriatic coast on the south, Konjic on the north, along the Neretva river and its right bank on the west, and extending to Lake Shkodra to the southeast. From the 3rd century BC to 168 BC the capital cities of the Ardiaean State were Rhizon and Scodra.

The Ardiaean kingdom was transformed into a formidable power—both on land and sea—under the leadership of Agron of Illyria. During this time, Agron captured parts of Epirus, Corcyra, Epidamnos, and Pharos in succession, establishing garrisons there. The Ardiaean realm became one of Rome's major enemies, and the primary threat to it in the Adriatic Sea. A series of wars were fought between the Roman Republic and the Illyrian (Ardiaean-Labaeatan) kingdom in the 3rd–2nd centuries BC. Polybius (203 BC–120 BC) wrote that they were subdued by the Romans in 229 BC. The Epitome of Livy reports the Roman consul Fulvius Flaccus put down an uprising in 135 BC undertaken by Ardiaei and Pleraei in Roman Illyria.

During the Second Punic War with Carthage, Rome's earliest known annalists Quintus Fabius Pictor and Lucius Cincius Alimentus recorded history in Greek, and relied on Greek historians such as Timaeus. Roman histories were not written in Classical Latin until the 2nd century BCE with the Origines by Cato the Elder. Contemporary Greek historians such as Polybius wrote about the rise of Rome during its conquest of Greece and ascension as the primary power of the Mediterranean in the 2nd century BCE. Moving away from the annalist tradition, Roman historians of the 1st century BCE such as Sallust, Livy, and even Julius Caesar wrote their works in a much fuller narrative form. While Caesar's De Bello Gallico focused specifically on his wars in Gaul, Roman works that served as a broad universal history often placed heavy emphasis on the origin myth of the founding of Rome as a starting point. These works formed the basis of the Roman historiographic models utilized by later Imperial authors of the Principate era, such as Tacitus and Suetonius.

The Achaean League (Ancient Greek: Κοινὸν τῶν Ἀχαιῶν, romanized: Koinon ton Akhaion, lit. 'League of Achaeans') was a Hellenistic-era confederation of Greek city-states on the northern and central Peloponnese. The league was named after the region of Achaea in the northwestern Peloponnese, which formed its original core. The first league was formed in the fifth century BC. Although the first Achaean League is much less well documented than its later revival, it maintained a recognizable federal structure through the early Hellenistic period, but later fell into a period of dormancy under growing Macedonian influence. The more famous second Achaean League was established in 280 BC. First it was an ally of Antigonid Macedon at the Cleomenean War, Social War and First Macedonian War and a rival of the Aetolian League and Sparta. As a rival of Antigonid Macedon and an ally of the Roman Republic since the Second Macedonian War, the league played a major role in the expansion of Rome into Greece. This process eventually led to the League's conquest and dissolution by the Romans in 146 BC.

The League represents the most successful attempt by the Greek city-states to develop a form of federalism, which balanced the need for collective action with the desire for local autonomy. Through the writings of the Achaean historian and statesman Polybius, this structure has had an influence on the constitution of the United States and other modern federal states.

The Macedonian Wars (214–148 BC) were a series of conflicts fought by the Roman Republic and its Greek allies in the eastern Mediterranean against several different major Greek kingdoms. They resulted in Roman control or influence over Greece and the rest of the eastern Mediterranean basin, in addition to their hegemony in the western Mediterranean after the Punic Wars. Traditionally, the "Macedonian Wars" include the four wars with Macedonia, in addition to one war with the Seleucid Empire, and a final minor war with the Achaean League (which is often considered to be the final stage of the final Macedonian War). The most significant war was fought with the Seleucid Empire, and both this and the wars with Macedonia effectively marked the end of these empires as major world powers, even though neither of them led immediately to overt Roman domination. Four separate wars were fought against the weaker power, Macedonia, due to its geographic proximity to Rome, though the last two of these wars were against haphazard insurrections rather than powerful armies. Roman influence gradually dissolved Macedonian independence and digested it into what was becoming a leading empire. The outcome of the war with the now-deteriorating Seleucid Empire was ultimately fatal to it as well, though the growing influence of Parthia and Pontus prevented any additional conflicts between it and Rome.

From the close of the Macedonian Wars until the early Roman Empire, the eastern Mediterranean remained an ever shifting network of polities with varying levels of independence from, dependence on, or outright military control by, Rome. According to Polybius, who sought to trace how Rome came to dominate the Greek east in less than a century, Rome's wars with Greece were set in motion after several Greek city-states sought Roman protection against the Macedonian Kingdom and Seleucid Empire in the face of a destabilizing situation created by the weakening of Ptolemaic Egypt.

Timaeus of Tauromenium (Ancient Greek: Τιμαῖος; born 356 or 350 BC; died c. 260 BC) was an ancient Greek historian. He was widely regarded by ancient authors as the most influential historian between the time of Ephorus (4th century BC) and Polybius (2nd century BC). In the words of scholar Lionel I. C. Pearson, Timaeus "maintained his position as the standard authority on the history of the Greek West for nearly five centuries."

Polemic (/pəˈlɛmɪk/ pə-LEHM-ick, US also /-ˈlimɪk/ -⁠LEEM-ick) is contentious rhetoric intended to support a specific position by forthright claims and to undermine the opposing position. The practice of such argumentation is called polemics, which are seen in arguments on controversial topics. A person who writes polemics, or speaks polemically, is called a polemicist. The word derives from Ancient Greek πολεμικός (polemikos) 'warlike, hostile', from πόλεμος (polemos) 'war'.

Polemics often concern questions in religion or politics. A polemical style of writing was common in Ancient Greece, as in the writings of the historian Polybius. Polemic again became common in medieval and early modern times. Since then, famous polemicists have included satirist Jonathan Swift, Italian physicist and mathematician Galileo, French theologian Jean Calvin, French Enlightenment writer, historian, and philosopher Voltaire, Russian author Leo Tolstoy, socialist philosophers Karl Marx and Friedrich Engels, novelist George Orwell, playwright George Bernard Shaw, communist revolutionary Vladimir Lenin, linguist Noam Chomsky, social critics H. L. Mencken, Christopher Hitchens and Peter Hitchens, and existential philosophers Søren Kierkegaard and Friedrich Nietzsche.

Euthydemus I (Greek: Εὐθύδημος, Euthýdēmos, c. 260 BC – 200/195 BC) was a Greco-Bactrian king and founder of the Euthydemid dynasty. He is thought to have originally been a satrap of Sogdia, who usurped power from Diodotus II in 224 BC. Literary sources, notably Polybius, record how he and his son Demetrius resisted an invasion by the Seleucid king Antiochus III from 209 to 206 BC. Euthydemus expanded the Bactrian territory into Sogdia, constructed several fortresses, including the Derbent Wall in the Iron Gate, and issued a very substantial coinage.
