Encounters and disagreements of the military orders at the border wars between Castille and Portugal in the 14th century

This work aims to show the encounters, whether friendly or not, between the Castilian and the Portuguese military orders throughout their integration into the hosts of those kingdoms in the fourteenth century. We study the presence and intervention of the military orders in the wars of attrition or border wars between both spaces. Those wars were the product of the policy in the respective monarchies, which claimed to impose their criteria and their power in their relations. Likewise, the desire of both Crowns to control and dominate the orders can be observed, as well as the consequences of these conflicts at the border.
