Mora de Rubielos is a municipality located in the mountainous area of the Iberian System, province of Teruel, Aragon, Spain.

During the Middle Ages, the territory of Mora was reconquered by the troops of Alfonso II, being until the take of Rubielos in 1204 the most advanced position of the Christian forces against Muslims in the Kingdom of Valencia.

Mora was occupied by the Spanish troops in the War of the Two Peters but returned to Aragonese hands in 1364, receiving the privilege of Pedro IV for which it undertook not to separate it from the crown.

In a phase of the Battle of Teruel (1937 - 1938), after the fall of Andorra and Alcañiz, Mora de Rubielos was the capital of the republican-held area.

[2] By May 1938, the territory in Republican rule in the province was defended by a set of staggered lines of a hundred kilometers long known as the Grande Arche de Mora Rubielos.
