text: Studying the works of Niccolò Machiavelli, such as The Prince, was considered necessary for any king in Europe to rule effectively. In 1739, Frederick finished his Anti-Machiavel, an idealistic rebuttal of Machiavelli. It was written in French—as were all of Frederick's works—and published anonymously in 1740, but Voltaire distributed it in Amsterdam to great popularity. Frederick's years dedicated to the arts instead of politics ended upon the 1740 death of Frederick William and his inheritance of the Kingdom of Prussia. Frederick and his father were reconciled at the latter's death, and Frederick later admitted, despite their constant conflict, that Frederick William had been an effective ruler: "What a terrible man he was. But he was just, intelligent, and skilled in the management of affairs... it was through his efforts, through his tireless labour, that I have been able to accomplish everything that I have done since."
  Inheritance
  Frederick was twenty-eight years old when his father died and he ascended to the throne of Prussia. Frederick William I had left him with a highly militarised state. Prussia was the twelfth largest country in Europe in terms of population, but its army was the fourth largest, after France, Russia and Austria. Prussia had one soldier for every 28 citizens, whereas Britain only had one for every 310, and the military absorbed 86% of Prussia's state budget. The Prussian infantry trained by Frederick William I were, at the time of Frederick's accession, arguably unrivalled in discipline and firepower. By 1770, Frederick had doubled the size of the huge army he had inherited. The situation is summed up in a widely translated and quoted aphorism attributed to Mirabeau, who asserted in 1786 that "" ("Prussia was not a state in possession of an army, but an army in possession of a state"). Using the resources his frugal father had cultivated, Frederick was eventually able to establish Prussia as the fifth and smallest European great power.
