Cale was 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. The Roman general
Decimus Junius Brutus Callaicus conquered the region and founded the Roman city
Portus Cale in around 136 BC. At the end of Brutus's campaigns,
Rome controlled the territory between the Douro and Minho rivers plus probable extensions along the coast and in the interior. It was only under
Augustus, however, at the end of the 1st century BC, that present north Portugal and
Galicia were fully pacified and under Roman control. During the Roman occupation, the city developed as an important commercial port, primarily in the trade between
Olisipo (the modern
Lisbon) and
Bracara Augusta (the modern
Braga). As the Roman Empire declined, these regions fell under
Suebi dominion, between 410 and 584. These
Germanic invaders settled mainly in the areas of Braga (
Bracara Augusta), Porto (
Portus Cale),
Lugo (
Lucus Augusti) and
Astorga (
Asturica Augusta). Bracara Augusta, capital of Roman
Gallaecia, became the capital of the Suebi. As trade collapsed, Portus Cale went into decline. Another Germanic people, the
Visigoths, also invaded the
Iberian Peninsula and would eventually conquer the Suebi kingdom in 584. The region around Cale became known by the Visigoths as
Portucale. Portus Cale would fall under the
Moorish invasion of the
Iberian Peninsula in 711. In 868,
Vímara Peres, a
Christian warlord from
Gallaecia and a vassal of the King of
Asturias,
Léon and
Galicia,
Alfonso III, was sent to
reconquer and secure from the Moors the area from the
Minho River to the
Douro River, including the city of Portus Cale, and founded the First County of Portugal or
Condado de Portucale.
Portus Cale is thus the former name of current-day
Porto and
Vila Nova de Gaia's riverside area, that would be used to name the whole region and, later, the country. ==Origin of Portugal's name==
