Wealth of Nations by Adam Smith was first published in 1776, a few months before the American Declaration of Independence founded the first fully capitalist revolution trying to seperate itself from a monarchy. While the US would adopt a lot of Smith’s ideas, most of their philosophy on how to form a government came from Locke, with some Calvanism and Hobbes thrown in, all of whom were from the century prior.
All this to say yes, classical liberalism was conceived in the late 1600s going into the 1700s, then put into practice by the end of the 18th. Century.
