Disputed inheritance

edit

When George of Lencastre, 2nd Duke of Aveiro died, in 1578 in the Battle of Alcácer Quibir, together with King Sebastian I of Portugal and most Portuguese nobles, the Dukedom of Aveiro was claimed by two pretenders:

  • his daughter, Juliana of Lencastre (1560–1636);
  • his cousin, Álvaro of Lencastre (1540–1626), his closest male relative, son of Alphonse of Lencastre (Afonso de Lencastre), 2nd son of Infante George of Lencastre.

According to the Lei Mental ("Mental Law"),[a] females could not inherit their father’s lands and fiefs (except with a specific royal permission). That was why Álvaro of Lencastre claimed his cousin's inheritance, to prevent the extinction of such a remarkable aristocratic House.

This dispute took about 2 decades, and finally, King Philip I of Portugal (also known as Philip II of Spain) decided that Dom Álvaro should marry his cousin, Dona Juliana, in order to inherit his family titles and estates, and they became jointly 3rd Dukes of Aveiro.

This marriage took place in 1598 and, for that occasion, the King granted the Dukes special honours:

The Ducal Palace was located in Azeitão, where, attached to the palace, they also built a hospital. They granted a huge protection to the Arrábida convent, founded by the 1st Duke, John of Lencastre, where they both are buried.

The couple had sixteen children:
