Teruel is a city in Aragon, located in eastern Spain, and is also the capital of Teruel Province. It had a population of 35,900 as of 2022, making it the least populated provincial capital in Spain. It is noted for its harsh climate, with a wide daily variation on temperatures and its renowned jamón serrano, its pottery, its surrounding archaeological sites, rock outcrops containing some of the oldest dinosaur remains of the Iberian Peninsula, and its famous events: La Vaquilla del Ángel during the weekend closest to 10 July and "Bodas de Isabel de Segura" around the third weekend of February.

Alfonso II, called the Chaste or the Troubadour, was the King of Aragon and, as Alfons I, the Count of Barcelona from 1164 until his death. The eldest son of Count Ramon Berenguer IV of Barcelona and Queen Petronilla of Aragon, he was the first King of Aragon who was also Count of Barcelona. He was also Count of Provence, which he secured from Douce II and her would-be father-in-law Raymond V, Count of Toulouse, from 1166 until 1173, when he ceded it to his brother, Ramon Berenguer III. His reign has been characterised by nationalistic and nostalgic Catalan historians as l'engrandiment occitànic or "the Pyrenean unity": a great scheme to unite various lands on both sides of the Pyrenees under the rule of the House of Barcelona.
