The strengthening of the committees of correspondence in the 1770s also marked the creation of what Gordon S. Wood terms "a new kind of popular politics in America." Wood writes that "the rhetoric of liberty now brought to the surface long-latent political tendencies. Ordinary people were no longer willing to trust only wealthy and learned gentlemen to represent them ... various artisan, religious, and ethnic groups now felt that their particular interests were so distinct that only people of their kind could speak for them. In 1774 radicals in Philadelphia demanded that seven artisans and six Germans be added to the revolutionary committee of the city."
