> A 13th-century king who sponsored astronomical tables still used centuries later, codified law in the vernacular for the first time in Castile, and chased a German crown he'd never wear — all while his own son turned the realm into a battlefield.

## Bio

Alfonso X became King of Castile, León and Galicia on 1 June 1252. Five years later, a dissident faction elected him king of Germany on 1 April 1257, a claim he'd renounce in 1275 after debasing Castile's coinage to fund the pursuit. His scientific interests earned him the nickname "the Astrologer" and drove him to sponsor the Alfonsine tables; the Alphonsus crater on the Moon now carries his name. He commissioned historians who, for the first time since Isidore of Seville around 600, framed Spain within world history, and introduced the Siete Partidas, Castile's first vernacular law code. He founded the Mesta, an association of sheep farmers in the central plain, won a war with Portugal, lost ground against Granada, and spent his final years in civil war against his eldest surviving son, the future Sancho IV — a fight that outlasted him when he died on 4 April 1284.
