Carlos, Don

Carlos, Don, the brother of Ferdinand VII. of Spain, on whose death he laid claim to the crown as heir, against Isabella, Ferdinand's daughter who by the Salic law, though set aside in her favour by her father, had, he urged, no right to the throne; his cause was taken up by a large party, and the struggle kept up for years; defeated at length he retired from the contest, and abdicated in favour of his son (1785-1855).
