Munia is from the Old Spanish-Basque muniño (hill, mound). **Munia Mayor (c. 990-1066)** was the Castilian princess and **wife of Sancho III the Great of Navarre** — through her, the kingdoms of Castile and Navarre were eventually united in their son Ferdinand I, **forming the foundation of medieval Spain**.
Sometimes called Mayor of Castile.
Munia reduces to three — the number of Castilian queen.
