Rome tried to increase both the numbers of its people and their well-being, and hence their wealth, but it was not until the 16th century that European rulers were urged to achieve these aims by the power of the state to enforce public health. By the 17th century, absolutist states such as France, Austria and especially Germany had created an administrative profession of enlightened despotism, with "medical police" to encourage healthy and thus wealth-producing citizens. Johann Peter Frank (1745-1821) was the profession's exemplar with his 6,262 page System einer vollstandigen medicinischen Polizey, leading to comprehensive public health legislation in German-speaking states, followed by more libertarian countries such as Britain and the United States. However, controversy continues on the role of government in trying to save its citizens, and especially their children, from harming themselves and/or others by their actions and omissions.
