African-American heritage of presidents of the United States
Calvin Coolidge's mother Victoria Moor was claimed to be of a mixed-race family in Vermont. Vaughn noted that her surname was derived from "Moor", a European term for people of North Africa. He did not note that another meaning of her surname is the landscape feature of moor or bog. People's surnames were often based on such landscape features when surnames became generally adopted in 14th century England. Moor/Moore is a common name in England, Scotland, and Ireland.
Iberian Peninsula
From the 8th–15th centuries, only the southern part of the Iberian Peninsula was part of the Islamic world. It became a center of culture and learning, especially during the Caliphate of Córdoba, which reached its height of its power under the rule of Abd-ar-Rahman III and his successor al-Hakam II. The Muslims, who were initially Arabs and Berbers, included some local converts, the so-called Muladi. The Muslims were referred to by the generic name, "Moors" The Reconquista gained momentum on c. 718, when the Christian Asturians opposed the Moors.
