Portugal's name derives from the Roman name Portus Cale. Cale was the name of an early settlement located at the mouth of the Douro River, which flows into the Atlantic Ocean in the north of what is now Portugal. Around 200 BC, the Romans took the Iberian Peninsula from the Carthaginians during the Second Punic War, and in the process conquered Cale and renamed it Portus Cale (Port of Cale). During the Middle Ages, the region around Portus Cale became known by the Suevi and Visigoths as Portucale. The name Portucale evolved into Portugale during the 7th and 8th centuries, and by the 9th century, that term was used extensively to refer to the region between the rivers Douro and Minho, the Minho flowing along what would become the northern border between Portugal and Spain. By the 11th and 12th century, Portugale was already referred to as Portugal.
