Roman EmpireThe Roman Empire was the largest in the ancient world and at its height controlled the land around the Mediterranean and most of continental Europe, with the exception of modern-day Germany, Denmark, and Russia. The incipient Roman Empire led to the demise of the Roman Republic and the accession of Octavian (better known by his posthumous title Augustus Caesar).
The Punic Wars
The first lands occupied by the Romans were in the Italian peninsula. From the days of the creation of the Roman Republic with the expulsion of the Tarquin dynasty in 510 BCE, the Romans had started attacking and ruling lands held by rival cities in central Italy. Rome's being sacked by the Gauls in 390 BCE significantly weakened it in the eyes of many. It rebuilt its military strength, and its defeat of Carthage in the First Punic War (264–241 BCE) led to Rome gaining a foothold in Sicily. From 241 until 218 BCE the Romans conquered Sardinia, Corcyra (modern-day Corfu), and Lombardy (northeastern Italy). During the Second Punic War, when Hannibal invaded the Italian peninsula in 218 BCE, the Romans were able to stop his attack on Rome, but their hold over the Italian peninsula was tenuous. Hannibal exploited this by forming alliances with the Gauls in northern Italy (Cisalpine Gaul) and also with predominantly Greek cities in the south, such as Capua and Tarentum.
When Hannibal was recalled to North Africa to defend Carthage and defeated at the Battle of Zama in 202 BCE, the Romans expanded their landholdings, taking many areas that had sheltered Hannibal during his 15 years in the Italian peninsula. The defeat of Hannibal also gave them the confidence to attack and conquer other lands, initially parts of Spain, and then attack Syria in 191 BCE.
This came about over tensions between Rome and the Seleucid Empire, with Rome declaring war in 192 BCE and attacking in the following year. Ptolemy V of Egypt allied himself with Rome against his neighbor. A Roman fleet commanded by Gaius Livius destroyed the Seleucid navy off the coast of Greece in 191 BCE and again in the following year at Eurymedon where Hannibal was helping the Seleucids in his first (and last) naval battle. At the same time a large Roman army advanced into Asia Minor and in December 190 BCE, at the Battle of Magnesia, destroyed the Syrians. In an agreement signed at Apameax, the Romans returned most of the land they had taken, only retaining the islands of Cephalonia and Zacynthus (modern-day Zante)...
