Achaean War in the context of "Fourth Macedonian War"

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.

The Battle of Corinth of 146 BC, also known as the Battle of Leucapetra or the Battle of Lefkopetra, was a decisive engagement fought between the Roman Republic and the Greek city-state of Corinth and its allies in the Achaean League. The battle marked the end of the Achaean War and the beginning of the period of Roman domination in Greek history, and is also notable for the complete and total destruction of Corinth by the Romans in its aftermath.

The Romans had moved swiftly since the war's beginning a few weeks earlier; they had destroyed the main Achaean force at Scarpheia, conquered Boeotia and then proceeded to Corinth itself. Despite the Roman successes, the Achaeans refused to surrender and gathered a final army for the defense of the League's capital of Corinth, where they engaged the Romans in battle. In a few hours of fighting, the Achaeans were soundly routed, with their troops killed, captured, or put to flight. After a few days' waiting, the Romans entered the city, and, on the orders of Mummius, set it on fire, killed all the men and enslaved all the women and children, after which the rest of Greece was subjugated by Rome.

The 2nd century BC started the first day of 200 BC and ended the last day of 101 BC. It is considered part of the Classical era, although depending on the region being studied, other terms may be more suitable. It is also considered to be the end of the Axial Age. In the context of the Eastern Mediterranean, it is the mid-point of the Hellenistic period.

Fresh from its victories in the Second Punic War, the Roman Republic continued its expansion in the western Mediterranean, campaigning in the Iberian Peninsula throughout the century and annexing the North African coast after the destruction of the city of Carthage at the end of the Third Punic War. They became the dominant force in the Aegean by destroying Antigonid Macedonia in the Macedonian Wars and Corinth in the Achaean War. The Hellenistic kingdoms of Ptolemaic Egypt and Attalid Pergamon entered into subordinate relationships with the Romans – Pergamon was eventually annexed. The end of the century witnessed the evolution of the Roman army from a citizen army into a voluntary professional force, which later scholars would misattribute to putative reforms by noted general and statesman Gaius Marius (the so-called Marian Reforms).
