It was decided that any future aggression by France would be prevented by creating strong neighbouring states. Belgium and the Netherlands were formed into an independent bloc, Prussia held the Rhineland, the kingdom of Sardinia and Piedmont was boosted in west Italy, and Austria regained Lombardy and Venice. Much of the rest of Italy was returned to the pre-1796 situation, the Pope got the Papal States back, and the old Holy Roman Empire was grouped into forty one, later thirty eight, states in a German Confederation. Russia retook much of Poland, and Spain welcomed back the Bourbons.
