The goal of Izquierda Castellana is the attainment of what they call a united Castile, overcoming the current division of the Castilian "nation" between five autonomous regions and a comarca. It emphasizes socialism, sovereignty and republicanism, principles it reaffirms each year on April 23, in a special ceremony in the municipality of Villalar de los Comuneros. This day is celebrated by Castilian nationalist organizations such as Izquierda Castellana and Tierra Comunera as the National Day of Castile, but officially it is the festivity of the autonomous region of Castile and León.
Tierra Comunera
A Castilian nationalist political party that seeks the defense of the rights and freedoms of the Castilian people, the constant exercise of their decision-making capacity, the progressive transformation of their society in order to achieve freedom and the preservation of their historical heritage, as the most valuable legacy to pass on to future generations. It currently does not assume a social, economic, and cultural role that defines Castile. It holds great value towards many aspects of the human nature, which includes cultural and environmental ideals, its production of raw materials of high quality, and most importantly, the existence of a political power at the service of its citizens, should allow the Castilian people build a society more prosperous and developed, that satisfaction appropriate to the needs of the people. As an organization that is fully committed to unify the Castilians amongst themselves and the rest of Spain, Tierra Comunera is responsible for multiple organized experiences that are developed by the people giving them continuity and gathering the best thing of all of them to plan a way that incorporates the illusion of all the persons and sectors that believe for a possible and united Castile.
Yesca
A Castilian youth organization that specialized in combat action that creates struggles by the Revolutionary Youth of their land: Castilla. Yesca arose from the militant representation that during the decade of the 90s and the early years of the new millennium that was carried out by the Revolutionary Youth Castilian. It was not simply a change of name but the natural evolution of the project after years of struggles and experiences of another step in the construction of a real Spanish organization qualified to give answers to the problems that they suffer as young. Yesca is committed to bring together people that want to real changes in society, fighting from the framework of the construction of Castile between everyone. It is something that traditionally ignite the spark; the symbolic name presents to us as what we aspire to be and a catalytic tool of ideas and actions that will lead us to kindle the flame of the social revolution, gender and national they need.
For the last three decades, tens of thousands of Castilian attend "Villarlar of the Comuneros" on April 23 to celebrate the day of Castile. The Battle of Villalar was a battle in the Revolt of the Comuneros fought near the town of Villalar in Valladolid province, Spain. The royalist supporters of King Charles I won a crushing victory over the comuneros rebels. Three of the most important rebel leaders were captured, Juan de Padilla, Juan Bravo, and Francisco Maldonado. They were executed the next day, effectively ending armed resistance to Charles I. The Battle of Villalar represents an important historical event in Castile because it marked the end of autocratic Spanish monarchy.
