The Arabs arrived on the Iberian Peninsula in 711 CE, and when their occupation ended in 1492, they left a big impact on the culture, language, architecture, and cuisine in Spain. There, they established a presence that lasted for centuries. 

The Spanish language has more than 4000 words that have their roots in Arabic. For instance, "azúcar" (sugar), "aceite" (oil), "naranja" (orange), and "azafrán" (saffron) all trace their etymology back to Arabic origins. Additionally, many Spanish place names are of Arab descent, e.g. ‘Madrid’, meaning ‘breeze’ in English. 

The Moorish rule introduced features of Islamic architecture, such as geometric patterns, tilework and calligraphy. Evidence of this is seen through Alhambra in Grenada, and the Great Mosque of Córdoba. 

Moreover, Arab culture brought advancements in fields like medicine, astronomy and mathematics. More specifically, the father of algebra was Al-Jwarizmi, whose face was also on the cover of students’ algebra books in Mexico. 

The Arabs also brought many foods and spices from overseas, like nutmeg, cinnamon and dates. This had an impact on the Spanish cuisine, which we still observe today in desserts like turrón, a type of nougat made with almonds and sugar, both of which the Arabs also introduced all those years ago.
