This treaty established a long-standing alliance between England and Portugal, underpinned by mutual support in military conflicts and trade benefits. The historical context of the treaty was marked by a desire for mutual security among nations, which not only enriched the diplomatic relations between these two kingdoms but also illustrated the evolving nature of international treaties during the medieval period.
