[EN] Leonese Wrestling (lucha leonesa, also known as aluches or luches) is an ancient wrestling style that nowadays is practised as a traditional sport in the province of León, Spain. Unlike many other wrestling styles, which were popular across the Spanish territory during most of the 20th century, it has resisted the many crises that led to their disappearance. In contrast, aluches soon enough found strong support in the later called movement of “Cultural Leonesism”, which promoted Leonese wrestling as an expression of Leonese culture and identity. For some decades, the “new” version of Leonese Wrestling, which started to follow a sportification process, coexisted with the old-style one, which was more local and diverse in terms of cultural elements, until it vanished. From then on, Leonese Wrestling has evolved, having as main priorities its development as a sport and the maintenance of its identity and value as a cultural asset. This chapter describes the evolution of Leonese Wrestling since the first decades of the 20th century to date, taking as reference the conception of Leonese Wrestling as a sport and an identitary tradition, with both aspects not always easy to balance and usually leading to conflict among Leonese Wrestling actors and stakeholders.
