When did Madrid become capital of Spain?
Almudena Cathedral
When the capital of Spain was transferred from Toledo to Madrid in 1561, the seat of the Church in Spain remained in Toledo and the new capital had no cathedral. Plans to build a cathedral in Madrid dedicated to the Virgin of Almudena were discussed as early as the 16th century but even though Spain built more than 40 cities in the new world during that century and plenty of cathedrals, the cost of expanding and keeping the Empire came first and the construction of Madrid's cathedral was postponed. Making the cathedral the largest that the world had ever seen was then a priority, all other main Spanish cities had centuries old cathedrals, Madrid also has old churches but the construction of Almudena only began in 1879.
Castile (historical region)
Leonese regionalists want Castile and León to be dissolved and become an autonomous community in its own right as the Leonese Country. Cantabria was previously considered as part of Old Castile, but they have their own identity and had achieved independence from Castile in the 1970s and are now a comunidad autonoma in their own right. Madrid had been in New Castile until the 1970s and has traditionally been considered Castilian. However, its status as the capital of Spain, meant that it gained its own autonomous community. Also, its people are not all Castilian as there have been immigration from other regions in Spain and indeed the world. In terms of cultural identity, there is a divide and controversy. Older Madrid people as well as Castilians nationalist in the region consider their city to be in Castile (cultural identity). Younger Madrid people, look at the modern reality of the administration, and do not consider it to be in Castile, as there is no reference to it in the name or the symbols of the autonomous community. However, the folk culture in the Madrid region is Castilian, even though the city itself has its own folklore, the chotis. As for La Mancha, they are still in Castile as their autonomous community is called Castile–La Mancha. However, their cultural identity focuses on the La Mancha rather than on the Castile. They have their own identity even though they are recognised as fully Castilian, for example, they had no language of their own, unlike, León.
