December 12, 1474

Isabella I of Castile

Official news of Henry IV's death reaches Isabella in Segovia

Nothing was proclaimed on this date. Two councillors rode from Madrid with the news, and Isabella waited until the following day to be made queen.

12 December 1474

Henry IV died in Madrid during the night of 11–12 December 1474, though historical authorities normally record 11 December as his death date. On the 12th the royal councillors Rodrigo de Ulloa and Garcí-Franco carried the official news from Madrid to Isabella in Segovia.

Isabella was not proclaimed that day. The ceremony took place on 13 December in Segovia's main square and the adjoining church of San Miguel, and a municipal act records that date.

The rival who got no banner

Henry's twelve-year-old daughter Juana was in Madrid, the city where he had died. The consulted archival synthesis reports that no immediate proclamation was made for her there.

Opponents disputed Juana's legitimacy, but her biological paternity cannot be resolved from the partisan allegations circulated by Isabella's supporters.

Not yet a war

The internationalised civil war did not begin when the messengers arrived in Segovia.

Afonso V of Portugal — Juana's maternal uncle, not yet her husband — invaded Castile and married her in May 1475.

The War of the Castilian Succession began with that invasion, five months after the news reached Segovia.
