# 206 BC

Year 206 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Philo and Metellus (or, less frequently, year 548 Ab urbe condita). The denomination 206 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

## Events
### By place
#### Roman Republic

* In the Battle of Ilipa (Alcalá del Río, near Seville) in Spain, the Carthaginian generals, Mago Barca and Hasdrubal Gisco, are defeated by the Roman general Publius Cornelius Scipio. Mago retreats to Gades (modern Cádiz) and then sails for the Balearic Islands.
* The Roman general Publius Cornelius Scipio secures Gades, thus making Roman control of Spain complete. With the effective withdrawal of the Carthaginians from Spain, Hispania becomes a Roman province.
* The city of Italica (northwest of modern Seville, Spain) is founded by Scipio as a place to settle for the Roman soldiers wounded in the Battle of Ilipa.
* After having successfully driven the Carthaginians out of Spain, Scipio returns in triumph to Rome and is elected consul. He then prepares to carry the war into Carthage's territory in North Africa.

#### Carthage

* Hasdrubal Gisco retreats to the coast and then crosses to North Africa, where he gives his daughter in marriage to Syphax, king of the Numidian Masaesyli tribe, to formalize their military alliance.
* After being an ally of Carthage and fighting with them, Numidian chieftain, Masinissa switches sides when the Carthaginians are driven from Spain and offers to assist Rome. Syphax expels his rival Masinissa and claims himself to be King of Numidia. The Romans support Masinissa's claim to the Numidian throne against Syphax, the pro-Carthaginian ruler of the Masaesyli tribe.

#### Persia

* Arsaces II, king of the Parthians, loses territory in battles with Euthydemus I, ruler of Bactria.
* Antiochus III marches across the Hindu Kush into the Kabul valley and renews his friendship with the Indian king Sophagasenus.

#### Greece

* The war between Macedonia and Rome drags on with no decisive advantage on either side. Rome's interest lies not in conquest, but in keeping Macedon, the Greek city-states and Greek political leagues continually divided and non-threatening.
