Aragon is a region in northeastern Spain that is an autonomous community coextensive with the medieval Kingdom of Aragon. It is composed of three provinces: Huesca, Zaragoza, and Teruel, and its capital is Zaragoza. Aragon has a rich geopolitical and cultural history from its pre-Roman, Celtic and Roman days, four centuries of Islamic rule as Marca Superior of Al-Andalus or kingdom (or taifa) of Saraqusta, as lands that once belonged to the Frankish Marca Hispanica, counties that later formed the Kingdom of Aragon, and eventually the Crown of Aragon.
Aragon is also known for its exceptional Mudéjar architecture and bullfighting tradition. It is a history-rich region of Spain, but most of Aragón constitutes terra incognita for the average tourist. However, it is ideal for a summer visit, especially Huesca, which is close to the mountains. Aragon is also known for the jota, a bounding, leaping dance that is part of its folklore.
In addition, Aragon is the name of an open-source software used to maintain and create decentralized autonomous organizations (DAOs) on the Ethereum blockchain. The Aragon Project was the first DAO framework to launch, and it is still experimenting and iterating to enable the digital organizations of the future.
Finally, the Kingdom of Aragon was a medieval and early modern kingdom on the Iberian Peninsula, corresponding to the modern-day autonomous community of Aragon, in Spain. It was originally a Carolingian feudal county around the city of Jaca, which in the first half of the 9th century became a vassal state of the kingdom of Pamplona (later Navarre) . The Kingdom of Aragon gave the name to the Crown of Aragon, created in 1150 with the dynastic union resulting from the marriage of the Princess of Aragon, Petronilla, and the Count of Barcelona, Ramon Berenguer IV.
