Castile-La Mancha is an autonomous community of Spain and is one of the most sparsely populated of Spain's autonomous communities. Its capital city is Toledo, and its most populated city is Albacete. Castile-La Mancha was formerly grouped with the province of Madrid into New Castile, but with the advent of the modern Spanish system of semi-autonomous regions, it was separated due to great demographic disparity between the capital and the remaining New-Castilian provinces.
