John Adams' achievements must also include raising a son who would follow his footsteps to the White House. John Quincy Adams became the sixth President of the United States and the only son of a former President to enter office until George W. Bush 175 years later. John Adams had brought John Quincy along on his diplomatic journeys to Europe and it was here that John Quincy started his political career as the secretary for the American Minister to Russia at the age of only 14. The major accomplishments of John Adams were often mirrored in his son's political career; for example, whereas the elder Adams made peace with the British in the Treaty of Paris in 1783, the younger Adams made peace with the British in the Treaty of Ghent in 1814. While the elder Adams disentangled the United States from European affairs after the Quasi-War with France, the younger Adams helped write the Monroe Doctrine which banned any further colonization in the Americas by the European powers. It seemed quite the family tradition to form American policy for future generations.
