Melvyn Bragg and guests discusses the Tudor State. In 1485 Henry Tudor slew Richard III and routed his army at The Battle of Bosworth Field. It was a decisive victory which founded a bold new dynasty; and this date like 1789 and 1066 has been taken by historians to be one of the great ‘year zeros’ of history: Suddenly the muddled Medieval World with its robber barons, feudal barbarism and bloody Wars of the Roses was banished, and the modern age of centralised government and King’s Justice was ushered in. But were the Tudors as instrumental in reshaping the British state as historians have liked to make out, and did their reign throughout the 16th century really lay the political foundations of our own age?
