POLITICAL IMPORTANCE 5 military values became, in 733, an ecclesiastical metropolis, for from this date the Archbishop of York was not only the ruler of the diocese of.York, but in addition spiritual head of the Church in the North of England. Further, there were established in the city branches of the civil government. Business of the state, both civil and military, and of the Church was regularly conducted at York from early times. This political importance lasted long and is intimately connected with' many events in the city's history. The fort and military, defences were renewed from time to time, and staff-work and general administration, whether Roman or Edwardian, were conducted from York. The king, from, whom York was rented by the citizens, had his official representatives with their offices permanently established here. The siege of 1644 after the royalist defeat at Marston Moor, was due mainly to the political importance of the city. In Danish times there were kings of York. The Archbishops, besides owning large areas of land in and around the, city, had their palace in the city. Monasteries grew up and flourished till the Dissolution ; churches and other religious buildings were everywhere. Further, from century to century, York was the home of important nobles of the realm, This political importance has persisted through the centuries. York still claims its traditional rank of second city in the kingdom.
