Early humans occupied sites around Burgos as early as 800,000 years ago. When the Romans took possession of what is now the province of Burgos, the site had been a Celtiberian city. In Roman times, it belonged to Hispania Citerior ("Hither Spain") and then toHispania Tarraconensis. In the 5th century, the Visigoths drove back the Suebi, then the Arabs occupied almost all of Castile in the 8th century, though only for a brief period, and left little if any trace of their occupation. Alfonso III the Great, king of León reconquered it about the middle of the 9th century, and built several castles for the defence of Christendom, which was then extended through the reconquest of lost territory. The region came to be known as Castile (Latin castella), i.e. "land of castles".
Burgos was founded in 884 as an outpost of this expanding Christian frontier, when Diego Rodríguez "Porcelos", count of Castile, governed this territory with orders to promote the increase of the Christian population; with this end in view he gathered the inhabitants of the surrounding country into one fortified village. The city began to be called Caput Castellae ("Cabeza de Castilla" or "Head of Castile"). The county (condado) of Burgos, subject to theKings of León, continued to be governed by counts and was gradually extended; one of these counts, Fernán González, established his independence.
In the 11th century, the city became the see of a Catholic bishop and the capital of the Kingdom of Castile. Burgos was a major stop for pilgrims on their way to Santiago de Compostela and a centre of trade between the Bay of Biscay and the south, which attracted an unusually large foreign merchant population, who became part of the city oligarchy and excluded other foreigners. Throughout the 13th and 14th centuries, Burgos was a favourite seat of the kings of León and Castile and a favoured burial site. The consejo or urban commune of Burgos was firmly in the hands of an oligarchic class
