With the end of the Portuguese monarchy in 1910, all titles of Portuguese nobility were initially abolished. Notwithstanding, although the status of nobility has not been recognised in law since 1910, legitimate titles of nobility (those granted by a reigning monarch before the 5th October 1910) have been given legal recognition and protection, including under article 26 of the Portuguese Constitution, in conjunction with articles 70 and 72 of the Civil Code, as established by decision of Portugal's Supreme Court of Justice in 2014.
