In 1172, Pero Ruíz d'Azagra managed to consolidate his power over the Señorío making that territory independent of the other Christian Kingdoms in the region. In 1190, with the signing of the Borja Accords, between Alfonso II of Aragon and Sancho VI of Navarre, the two monarchs agreed to a defensive pact against Alfonso VIII of Castile which gave official legitimacy to the Sinyoría d'Albarrazín with respect to the two kingdoms.[1]

Downfall and integration into the Kingdom of Aragón
The House of Azagra remained dominant in the region for six generations thanks to the support received from the Kingdom of Aragon. In 1281, with the signing of the Treaty of d'Ágreda by Peter III of Aragon and Alfonso X of Castile came to an agreement and Aragon was free to pursue territorial expansion in the region of Albarrazín and elsewhere.[2] In 1284, the Sinyoría d'Albarrazín was conquered by the Kingdom of Aragon after a lengthy siege lasting from April to September of that year. Attempts to recover the lands by the contemporary lord, Juan Núñez I de Lara, who decided to pursue an alliance with the Kingdom of France, were defeated. Peter III of Aragon, upon capturing the city, gave it as a gift to his illegitimate child with Inés Zapata, Ferdinand of Aragon.[3]
In 1300, James II of Aragon incorporated the lands and city of Albarracín into his dominion as a titled city.
