# List of heirs to the Spanish throne

This is a list of the individuals who were, at any given time, considered the next in line to inherit the throne of Spain, should the incumbent monarch die. Those who actually succeeded (at any future time) are shown in bold.
From the personal union of the Crown of Castile and the Crown of Aragon until the accession of the first Bourbon monarch in 1700, the heir to the Spanish throne was the person closest to the Spanish monarch according to the male-preference cognatic primogeniture. From the accession of Philip V until the Pragmatic Sanction of 1830, the heir to the Spanish throne was the person closest to the Spanish monarch according to the Salic law. The heir, whether heir apparent or heir presumptive, was often granted the title of Prince of Asturias.
Significant breaks in the succession, where the designated heir did not in fact succeed (due to usurpation, conquest, revolution, or lack of heirs) are shown as breaks in the table below.

* ↑ In 1660, Infanta María Teresa renounced her claim to the throne, in order to marry King Louis XIV of France. Later, the validity of her renunciation was contested, based on the fact that Spain failed to pay the dowry, which was pivotal for the succession of King Felipe V in 1700.
* ↑ Since the validity of the renunciation of María Teresa on her rights to the Spanish throne was contested, the succession was disputed among the heirs by cognatic primogeniture and the heirs established under the will of Felipe IV. The will entailed the throne on the heirs of his younger daughter Margarita Teresa.
* ↑ On 31 August 1724, Luis I died childless at age 17, just months after the abdication of his father, Felipe V. His heir would be his brother, Infante Fernando, who was only 10. Six days later, to avoid a regency and after much convincing and pressure, especially from Queen Dowager Isabel, Felipe V reluctantly accepted to be restored to the Spanish throne.
* ↑ On 25 November 1885, Alfonso XII died while Queen María Cristina was pregnant, so the throne went vacant, depending on whether the unborn child was a male or a female: a male would make that child king, while a female would make the eldest daughter (María de las Mercedes, Princess of Asturias) queen. During this period, María Cristina ruled as regent until her third child, a son, was born on 17 May 1886; he was King Alfonso XIII from birth.
* ↑ In 1933, Alfonso XIII's eldest two sons (Alfonso, Prince of Asturias and Infante Jaime) renounced their claims to the throne, so from then on Alfonso XIII's heir would be his third son, Infante Juan. In 1947, Francisco Franco restored the monarchy, confirmed by referendum, while appointing himself as Head of State for life. Having the power to appoint his successor, who would be king, Franco did not do so with Infante Juan, Count of Barcelona, and in 1969 he appointed Infante Juan's eldest son, Juan Carlos, Prince of Asturias, considering him to be more likely to preserve the Francoist regime after his death, which did not happen, as in 1975, Juan Carlos I promptly promoted Spanish transition to democracy. Finally, in 1977, Infante Juan renounced his headship of the Royal House of Spain, recognising his son, the King, as such.
