How successful was the Treaty of London of 1518 in fulfilling Henry VIII’s aims in foreign policy?

Whilst it may have appeared in the beginning that the Treaty of London - an international non-aggression pact which involved over twenty European rulers - satisfied Henry’s desire to put England at the forefront of the European stage, it was short-lived. When Emperor Maximilian died a mere four months later in 1519, and Charles V succeeded him, a huge shift in power changed the diplomatic situation. Charles, young and confident, entered into a longstanding enmity with Francis I of France with the intention of claiming supremacy over Europe; England in its role of peacekeeper became irrelevant once more. Due to their lack of experience in the nuanced field of foreign politics, both Henry and Wolsey were slow to anticipate the rapid changes in authority between the two powers. The Treaty of London therefore did not retain for Henry a significant role in Europe, with France and Spain undermining its core aims, hence it was unsuccessful in fulfilling Henry’s aims.
