OS LENCASTRE

Lencastre, Lancastre ou Alencastro são tudo grafias de único apelido
derivado da denominação de D. Filipa de Lencastre, rainha consorte
de El-Rei
D.João I, e proveniente este nome do titulo de seu pai, o
príncipe inglês
John de Gant, Duque de Lancaster. Como apelido, foi
dado pelo rei D. João II a seu filho natural legitimado, o chamado
senhor D. Jorge que foi duque de Coimbra e Mestre das Ordens de
Santiago e de Avis. Foi casado com D. Beatriz de Vilhena, filha do
senhor D. Álvaro de Portugal, filho do segundo Duque de Bragança
D. Fernando e de sua mulher D. Filipa de Melo, com geração que
deu continuidade a este apelido.
A descendência portuguesa do referido filho natural do Príncipe
Perfeito cedo se dividiu em dois ramos principais, o primogénito, dos
duques de Aveiro, que é hoje representado pela Casa dos
Marqueses de Lavradio, e o secundogénito, dos
comendadores-mores de Aviz cuja a primogenitura caíu na Casa dos
Condes de Vila Nova de Portimão.

House of Lancaster

Royal family of England. The line was founded by the second son of
Henry III, Edmund Crouchback, 1245–96, who was created earl of
Lancaster in 1267. Earlier (1254) the prince had been made titular king
of Sicily when the pope offered that crown to Henry III in order to keep
Sicily and the Holy Roman Empire separated. However, the English
barons refused financial support for the Sicilian wars, and the title was
withdrawn (1258). Later Edmund fought for his brother, Edward I, in
Wales and Gascony. His nickname “Crouchback,” or crossed back,
refers only to the fact that he went on crusade to Palestine in 1271
and, hence, was entitled to wear the cross. Edmund's son Thomas, earl
of Lancaster, 1277?–1322, led the baronial opposition to his cousin
Edward II. He was one of the lords ordainers and from 1314 to 1318
was virtual ruler of England. He tried unsuccessfully to drive the
Despensers (see Despenser, Hugh le) from England, was defeated at
the battle of Boroughbridge, and was beheaded for treason. Thomas's
brother, Henry, earl of Lancaster, 1281?–1345, was chief adviser to the
young Edward III in getting rid of the dominance of the queen mother,
Isabella, and her paramour, Roger de Mortimer, 1st earl of March. His
son, Henry, duke of Lancaster, 1299?–1361, was made duke in 1351
for his excellent service as a military commander in the early part of
the Hundred Years War. When he died without male heirs, his daughter
Blanche married the fourth son of Edward III, John of Gaunt, who
inherited the Lancaster lands in her right, and was made duke of
Lancaster in 1362. His son Henry deposed (1399) Richard II and
ascended the throne as Henry IV. In order to appear legitimate, Henry
devised the fiction that his ancestor Edmund Crouchback had actually
been Henry III's elder son but had been disinherited because he was a
hunchback. Later Lancastrian kings were Henry V and Henry VI. The
latter was deposed by the house of York in the course of the long
dynastic struggle known as the Wars of the Roses. However, through
the Beauforts, the legitimated descendants of John of Gaunt and
Catherine Swynford, the Lancastrian claims passed to the house of
Tudor.
