House of Barcelona
These counties came under the rule of the counts of Barcelona, who were Frankish vassals nominated by the emperor of the Franks, to whom they were feudatories (801–988). The earliest known use of the name "Catalonia" for these counties dates to 1117. At the end of the 9th century, the Count of Barcelona Wilfred the Hairy made his title hereditary and founded the dynasty of the House of Barcelona, which ruled Catalonia until 1410.
