The
Castilian people (Spanish:
castellanos) are certain inhabitants in regions of central
Spain including at least the eastern part of
Castile and León, the northern and eastern parts of
Castile-La Mancha, and the
Madrid community, who are the source of the
Spanish language (Castilian) among other aspects of cultural identity. However, not all people in the regions of the medieval
Kingdom of Castile think of themselves as Castilian. For this reason, the exact limits of what
Castile is today are disputed.
