In the 1790s, opposition political parties were new and not fully accepted. Government leaders often considered their opponents to be traitors. Historian Ron Chernow reports that Secretary of the Treasury Alexander Hamilton and President George Washington "regarded much of the criticism fired at their administration as disloyal, even treasonous, in nature." When an undeclared Quasi-War broke out with France in 1797–98, "Hamilton increasingly mistook dissent for treason and engaged in hyperbole." Furthermore, the Jeffersonian opposition party behaved the same way. After 1801, with a peaceful transition in the political party in power, the rhetoric of "treason" against political opponents diminished.
