Dukedoms in Portugal

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.
