Casa do Infantado

The House of the Infantado (Portuguese: Casa do Infantado) was an appanage for the second eldest son of the Portuguese monarch.

Created in 1654 by King John IV of Portugal, the properties and riches confiscated from the Marquis of Vila Real, supporters of House of Habsburg, during the Portuguese Restoration War. The House of the Infantado belonged to and was passed on to the second-born son of each King — i.e., the Infante that was not entitled to the crown — as his appanage. This member of the Portuguese Royal family was known as the Lord of the House of Infantado (Senhor da Casa do Infantado) or simply the Lord of Infantado (Senhor do Infantado).

The measure was intended to "perpetuate and extend as much as possible the blood of the royal family." The extinction of the House of Aviz in 1580 had brought the Kingdom of Portugal in personal union with Spain, de facto subjecting the country to Spanish rule. Thus the country's independence depended also on the fertility of the royal house. With a large income, second sons are encouraged to marry to produce cadet branches capable of perpetuating the royal line. The basis of the donation was the city of Beja, with the ducal title, which belonged to King Manuel I of Portugal. As this income was not enough, the lands Vila Real and Caminha, confiscated in 1641, were added to it.

The donation covered the villages, places, castles, padroados, land, forums, rights and duties for the second house, which guaranteed the title of Duke of Vila Real to the eldest son of Infante Dom Pedro. The House continued to receive new grants from the crown: the fifth of Queluz and their appurtenances; the palaces and houses of Corte-Real in Lisbon, which had belonged to the 2nd Marquis of Castelo Rodrigo; the town of Serpa and with their barns and de Moura; rents of the Military Order of Christ to which the infante had been named Commander; the marshlands of Golegã, Borba, Mouchões and Silveira, near the Tagus river, from São Liborio to Santarém; saboarias of Porto and villages and places of Entre Douro and Minho and Tras-os-Montes.
