constance of castile , duchess of lancaster

constance of castile -lrb- 1354 -- 24 march 1394 -rrb- was claimant of the castilian throne after the death of her father peter the cruel , her mother being maría de padilla , whom peter had secretly married but was then forced to repudiate , only to keep her as a mistress .
she married , at roquefort , near bordeaux , guienne , on 21 september 1371 , john of gaunt , 1st duke of lancaster , third son of edward iii of england and philippa of hainault , as his second wife .
her younger sister , infanta isabella , married edmund of langley , 1st duke of york , the fourth son of king edward iii and queen philippa .
on 9 february 1372 constance made a ceremonial entry into london as queen of castile , accompanied by edward , the black prince , and an escort of english and castilian retainers and london dignitaries .
crowds lined the streets to see her as she processed to the savoy palace in the strand where she was ceremonially received by her husband , who had proclaimed himself king of castile and león on 29 january .
this was the way for gaunt to obtain a kingdom of his own -lrb- he had also pursued scotland -rrb- , as his nephew richard ii and the descendants of his brother lionel of antwerp , 1st duke of clarence stood between him and the crown of england .
john of gaunt claimed the title of king of castile `` jure uxoris '' , and insisted that english nobles address him as `` my lord of spain '' , but was unsuccessful in his attempts to obtain the crown .
their daughter catherine of lancaster was married to the king of the trastámara line , henry iii of castile , thus uniting these two rival claims .
constance died at leicester castle and was buried at the church of the annunciation , newark , leicester .
