Edmund of Langley, 1st Duke of York
(June 5 1341
– August 1 1402
) was a younger son of King Edward III of England
and Philippa of Hainault
, the fourth of the five sons of the Royal couple who lived to adulthood. Like so many medieval princes, Edmund gained his identifying nickname from his birthplace: Kings Langley
. At the age of twenty-one, he was created Earl of Cambridge
. On 6 August 1385
, Edmund was created Duke of York
. He was the founder of the House of York
, but it was through the marriage of his younger son, Richard
, that the Yorkist
faction in the Wars of the Roses
made its claim on the throne.
Although marriages within the royal family and between royal families are the rule, it is interesting to note Langley's marital ties to his older brother, John of Gaunt
. Langley's first wife, Isabella of Castile
, was the sister of Gaunt's second wife, Constance of Castile
; his second wife, Joan Holland
, was the sister of Gaunt's daughter-in-law Margaret Holland
, wife of Gaunt's son John Beaufort
Langley's first wife, Isabella, was a daughter of Pedro "the Cruel" of Castile and María de Padilla. They had two sons and a daughter:
After Isabella's death in 1392, Langley married his cousin Joan Holland, whose great-grandfather Edmund of Woodstock, 1st Earl of Kent, was the half-brother of Langley's grandfather Edward II; she and Langley were thus both descended from King Edward I. The marriage produced no children.
Edmund of Langley died in his birthplace, and was buried there, in the church of the mendicant friars
. His dukedom passed to his eldest son, Edward.
