Macedonian Wars

Greece in the Roman era (Greek: Έλλάς, Latin: Graecia) describes the period of ancient Greece (roughly, the territory of the modern nation-state of Greece) as well as that of the Greek people and the areas they inhabited and ruled historically, from the Roman Republic's conquest of mainland Greece in 146 BC until the division of the Roman Empire in late antiquity. It covers the periods when Greece was dominated first by the Roman Republic and then by the Roman Empire.

In the history of Greece, the Roman era began with the Corinthian defeat in the Battle of Corinth in 146 BC. However, before the Achaean War, the Roman Republic had been steadily gaining control of mainland Greece by defeating the Kingdom of Macedon in a series of conflicts known as the Macedonian Wars. The Fourth Macedonian War ended at the Battle of Pydna in 148 BC with the defeat of the Macedonian royal pretender Andriscus.

Roman Italy is the period of ancient Italian history going from the founding and rise of Rome to the decline and fall of the Western Roman Empire; the Latin name of the Italian peninsula in this period was Italia (continued to be used in the Italian language). According to Roman mythology, Italy was the ancestral home of Aeneas, being the homeland of the Trojans progenitor, Dardanus; Aeneas, instructed by Jupiter, moved to Italy after the fall of Troy, and his descendants, Romulus and Remus, were the founders of Rome. Aside from the legendary accounts, Rome was an Italic city-state that changed its form of government from Kingdom (ruled, between 753 BC and 509 BC, by seven kings) to Republic, and then grew within the context of a peninsula dominated by the Gauls, Ligures, Veneti, Camunni and Histri in the North; the Etruscans, Latins, Falisci, Picentes, Umbri and Sabines in the Centre; and the Iapygian tribes (such as the Messapians), the Oscan tribes (such as the Samnites) and Greek colonies in the South.

The consolidation of Italy into a single entity occurred during the Roman expansion in the peninsula, when Rome formed a permanent association with most of other the local tribes and cities; and Italy's inhabitants included Roman citizens, communities with Latin Rights, and socii. The strength of the Italian confederacy was a crucial factor in the rise of Rome, starting with the Punic and Macedonian wars between the 3rd and 2nd century BC. As Roman provinces were being established throughout the Mediterranean, Italy maintained a special status with political, religious and financial privileges. In Italy, Roman magistrates exercised the imperium domi (police power), as an alternative to the imperium militiae (military power) exercised in the provinces.

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 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 Fourth Macedonian War (150–148 BC) was fought between Macedon, led by the pretender Andriscus, and the Roman Republic. It was the last of the Macedonian Wars, and was the last war to seriously threaten Roman control of Greece until the First Mithridatic War sixty years later.

The last Macedonian king of the Antigonid dynasty, Perseus, had been defeated and dethroned by the Romans in the Third Macedonian War in 168 BC. In the aftermath of the war, Rome took indirect control of the region through a system of client states, and imposed harsh terms to prevent Macedon from becoming a powerful state again. This system was successful in maintaining Roman hegemony for nearly two decades, but broke down when Andriscus, a Greek who bore a resemblance to Perseus, claimed to be the former king's son and re-established the Macedonian Kingdom with Thracian troops.

Polybius (/pəˈlɪbiəs/; Ancient Greek: Πολύβιος, Polýbios; c. 200 – c. 118 BC) was an ancient Greek historian of the middle Hellenistic period. He is noted for his Histories, a universal history documenting the rise of Rome in the Mediterranean in the third and second centuries BC. It covers the period 264–146, recording in detail events in Italy, Iberia, Greece, Macedonia, Syria, Egypt and Africa, and documents the Punic Wars and Macedonian Wars among many others.

Polybius's Histories is important not only for being the only Hellenistic historical work to survive in any substantial form, but also for its analysis of constitutional change and the mixed constitution. Polybius's discussion of the separation of powers in government, of checks and balances to limit power, and his introduction of "the people", all influenced Montesquieu's The Spirit of the Laws, John Locke's Two Treatises of Government, and the framers of the United States Constitution.

The Hellenistic armies is a term that refers to the various armies of the successor kingdoms to the Hellenistic period, emerging soon after the death of Alexander the Great in 323 BC, when the Macedonian empire was split between his successors, known as the Diadochi (Ancient Greek: Διάδοχοι).

Initially, the Hellenistic armies were very similar to those commanded by Alexander the Great, but during the era of the Epigonoi (Ἐπίγονοι, "Successors") the differences became obvious, with the Diadochi growing to favor large masses of soldiers rather than smaller, well-trained ones, and weight was valued over maneuverability. The limited availability of Greek conscripts in the east led to an increasing dependence on mercenary forces, whereas the Hellenistic armies in the west were continuously involved in wars, which soon exhausted local manpower, paving the way for Roman supremacy in the region.
