Its institutional system evolved over the centuries, establishing political bodies (such as the Courts, the Generalitat or the Consell de Cent) and legislation (constitutions, derived from the Usages of Barcelona) which limited the royal power and secured the political model of pactism. Catalonia contributed to further develop the Crown trade and military, most significantly their navy. Catalan language flourished and expanded as more territories were added to the Crown, including Valencia, the Balearic Islands, Sardinia, Sicily, Naples and Athens, constituting a thalassocracy across the Mediterranean. The crisis of the 14th century, the end of the rule of House of Barcelona (1410) and a civil war (1462–1472) weakened the role of the Principality in Crown and international affairs.
