Catalina de Lancáster
摘要
Catalina de Lancáster (1373–1418), daughter of John of Gaunt and Constanza de Castilla, played a pivotal role in uniting the rival dynastic lines of Castile through her marriage to Enrique III in 1388. As queen consort and later co-regent after Enrique’s death in 1406, Catalina navigated court power struggles and controversies surrounding her favorites. She championed Dominican spirituality, founding and patronizing monastic institutions like Santa María la Real de Nieva, and influenced Castilian literary culture, fostering court poetry and Marian devotion. Catalina’s surviving correspondence highlights her support for female relatives and descendants of Pedro I, particularly María de Castilla and Teresa de Ayala in Santo Domingo el Real de Toledo. Catalina is also notable for her associations with two of the first female writers in Castile, Leonor López de Córdoba and Constanza de Castilla.
