Portuguese ventures were intended to compete with the Muslim trans-Sahara caravans, which played a key
role in the highly profitable Muslim slave trade and also held a monopoly on West African gold and ivory.[15]
The Portuguese claimed territorial rights along the African coast by virtue of having invested time and treasure
in discovering it; the Castilian claim was based on their being the heirs of their Visigoth ancestors. In 1454 a
fleet of caravels from Seville and Cadiz traded along the African coast and upon their return, were intercepted
by a Portuguese squadron. Enrique IV of Castile threatened war. Afonso V appealed to the Pope for moral support
of Portugal's right to a monopoly of trade in lands she discovered.[16]
