Tordesillas (Spanish pronunciation: [toɾðeˈsiʎas]) is a town and municipality in the province of Valladolid, Castile and León, central Spain.

During the skirmishes between Henry IV and the nobility the city supported the monarchy, and again during the clashes between the Catholic Monarchs and Joanna La Beltraneja in 1476.

The Catholic Monarchs signed the Treaty of Tordesillas with the Portuguese crown in 1494, which established the line dividing the globe between Spain and Portugal for colonization purposes.

Despite Tordesillas' traditional support for the monarchy, in the Castilian War of the Communities by citizens of Castile against the rule of Charles V, the city took the side of the Comuneros.

However, in 1521, after nearly a year of rebellion, the reorganized supporters of the emperor Charles V struck a crippling blow to the comuneros at the Battle of Villalar, and finally royal troops of the Count of Haro captured Tordesillas.

The ongoing position of Tordesillas at a crossing of historic roads and modern highways has been the decisive factor in its economic survival and development.

His son Peter the Cruel had it embellished by Mudéjar artists, beautiful works at Santa Clara, though on a much smaller scale than they did in the Alcázar of Seville.

Queen Joanna of Castile and Aragon, who spent much of her life in confinement at the (later demolished) Royal Palace of Tordesillas, was first interred at the Santa Clara convent before her remains were transferred to Granada.

The Plaza Mayor is the historic and attractive central community space framed by the 17th century colonnade and porticos creating the arcade that encircles it.

Celebrations begin on 8 September, Patron Saint's Day of Tordesillas, the 'Virgen de la Guía' (Our Guiding Lady).

This celebration was banned in 2016 by the regional government over rising concerns about violent clashes between those who held views in favor of the tournament and those against it.

There had been attempts to block the celebration by members of animal-rights groups before and altercations between both locals and visitors in the years prior to the ban were escalating.
