The highest hereditary title in the Portuguese nobility. By tradition, there are a total of five royal and seven non-royal dukes in Portugal, out of 28 dukedoms that have ever been created. In the majority of cases, the title of duke was attributed to members of the high nobility, usually relatives of the Portuguese royal family, such as the second son of a monarch.
There are exceptions, like António José de Ávila, who, although not having any relation to the royal family, was given the title of duke of Ávila and Bolama.
Hereditary royal dukedoms
Courtesy royal dukedoms
These titles were occasionally given to other infantes of the royal family, but did not automatically descend to their heirs:
Noble dukedoms
All of these dukedoms are inherited, but only some of them are titles de juro e herdade – this meant that the reigning monarch was obliged to renew the title for its rightful heir whenever a titleholder died. Only Aveiro, Lafões, Terceira, Palmela, Saldanha and Loulé were dukedoms de juro e herdade. Some of these dukes (Cadaval, Terceira and Saldanha) enjoyed Honras de Parente, i.e. certain honours (of style and/or precedence) associated with being an officially recognised relative of the king.
