John I (Spanish: Juan I; 24 August 1358 \endash 9 October 1390) was king of the Crown of Castile from 1379 until 1390. He was the son of Henry II and of his wife Juana Manuel of Castile. He was the last monarch of Castile to receive a formal coronation.
King John was killed at Alcalá on 9 October 1390, when he fell off his horse while riding in a fantasia with some of the light horsemen known as farfanes, who were mounted and equipped in the Arab style.[1][50] His death was kept secret by Cardinal Pedro Tenorio for days who claimed he was only wounded. Since his son Henry III was still a minor at the time, a regency was set up to rule in his place. After his death, the body of John I was transferred to the city of Toledo for burial. His tomb is in the Chapel of the New Monarchs (La Capilla de los Reyes Nuevos) of the Cathedral of Toledo in Spain.[51][52]

John married Eleanor OF ARAGON. (Eleanor OF ARAGON was born on 20 Feb 1358 in El Puig de Santa Maria, Valencia, Spain and died on 13 Aug 1382 in Coeliar, Segovia, Spain.)
