Alfonso X is the Spanish king commonly linked to the legend that taverns should serve food with wine, inspiring tapas.
The story says Alfonso X, known as Alfonso the Wise, recovered from an illness by drinking wine with small portions of food. He supposedly ordered Castile’s taverns to serve wine covered by a small dish of food, so drinkers would eat before drinking more. The food is said to have helped prevent drunkenness.
This is a popular origin story rather than a firmly documented single event. The Spanish word tapa means “cover,” and another tradition says the food originally covered a glass. Regional customs and the modern tapas culture developed over centuries, so historians do not treat Alfonso X’s story as the complete explanation.
Alfonso X ruled Castile and León from 1252 until 1284 and was also an important patron of literature, law, and science. The legend survives because it neatly connects a royal order, wine service, and the name tapa.
