Primera Guerra Civil Castellana
This conflict has also been called the Second Castilian Civil War, but this name may lead to confusion with the other civil wars that involved Castile in the 14th and 15th centuries. Some authors refer to it as the War of Portugal; however, this name clearly represents a Castilian point of view and implicitly denies Juana's claim. At other times the term "Peninsular War" has been used, but it is easily confused with the Peninsular War of 1808–1814, part of the Napoleonic Wars. Some authors prefer the neutral expression War of 1475–1479.
