McCulloch v. Maryland was a case discussed by the US Supreme Court which led to the enactment of a landmark decision in 1819. It delimited the scope of the different goverment levels existing in the US. More specifically, it declared the supremacy of the federal goverment over the states, whose power to interfere with the federal decisions is limited.  Moreover, some of the federal powers are implied, which means that they are not explictly enumerated in the Constitution but authorized by its provisions.

In this case, the state of Maryland could not challenge the decision of creating a national bank that had been adopted at a federal level. The creation of a national bank was not listed as one of the powers of the federal goverment in the Constitution, therefore it is an implied power.

isolationism is a doctrine practiced by the united states for much of its history with the aim of not intervening in external affairs that did not pose a real threat to their country. the united states managed to maintain a state of political isolation throughout the nineteenth century and the first part of the xx. few nations have been able to maintain such a position for such a long period of time. historians argue that it is largely due to geographical reasons, given the physical distance between europe and the usa. uu the venataja of this situation is that the national state can spend its resources in satisfying all the needs of its inhabitants, without the need to invest in armament and equipment for a war that does not directly affect the country.
