These were the golden centuries, during the early Middle Ages; in the Kingdom of Galicia agricultural activities increased, trade became more generalised and art flourished in the 12th century.
Santiago would be the first place in Europe where polyphonic singing was heard.
The Middle Ages was also an era of great collective creation in Galicia, with the use of the Galician language, a Romance language, daughter of Latin, sister of Portuguese, that achieved literary maturity in the 13th century.
Kings, nobles and troubadours of all kinds sang of love in the lands of Galicia and Portugal.
The Medieval Galician songs constitute one of the treasures of Europe's cultural heritage.
