Ordenamiento de Alcalá

They are an important part of the principal legislative body of the Castilian Crown during the low Middle Ages until the 1505 Leyes de Toro.

This work represented the success of the lawyers (who had training in Roman law), who represented the interests of the king to increase the power of the monarchy (with the goal of creating an early absolute monarchy).

Finally in cases of doubt or silence from the king the nobles would give their interpretation.

However, the king had to yield to pressure from the nobles who wished to see recognized different land concessions and privileges during the continued revolutions and civil wars of the Middle Ages, especially in the turbulent years under the regency of his grandmother María de Molina, during his years as a minor and those of his father Fernando IV.

It can be seen that orders fixed in this law were incorporated later in compilations of the Modern Age; being faithfully maintained until the enactment of the Código Civil at the end of the 19th century.
