Extending from the mouth of river Minho in the North, to the mouth of river Guadiana in the south, a part of the current Portuguese/Spanish border dates to the ancient County of Portugal. From the Treaty of Zamora (1143), which marks the birth of Portugal, to the episode of the “Reconquista” that culminated in the Treaty of Badajoz (1267), which attributed the Algarve to Portugal, and the Treaty of Alcanizes (1297), a separation line was established that was rarely reviewed throughout more than 700 years.
