Traición (Treason Gate). Zamora was also the scene of fierce fighting in the fifteenth century, during the conflict between the supporters of Isabella the Catholic and Juana la Beltraneja. The Spanish proverb, No se ganó Zamora en una hora, literally, Zamora wasn't won in an hour, is a reference to these battles. It is the Spanish equivalent of the English proverb "Rome wasn't built in a day."
During the 12th century, the city was extraordinarily important for its strategic position in the wars between the Kingdom of León and Arabs to conquer the Iberian Peninsula. As a result, the city preserves many churches and buildings from that time. In the next centuries, the city lost its political and economic relevance and suffered emigration, especially to South America (where many other cities called Zamora were founded)
