Young America movement

The Young America Movement was an American political and cultural attitude in the mid-19th century. Inspired by European reform movements of the 1830s (such as Junges Deutschland, Young Italy and Young Hegelians), the American group was formed as a political organization in 1845 by Edwin de Leon and George Henry Evans. It advocated free trade, social reform, expansion southward into the territories, and support for republican, anti-aristocratic movements abroad. It became a faction in the Democratic Party in the 1850s. Senator Stephen A. Douglas promoted its nationalistic program in an unsuccessful effort to compromise sectional differences.

John L. O'Sullivan described the general purpose of the Young America Movement in an 1837 editorial for the Democratic Review:

Historian Edward L. Widmer has largely placed O'Sullivan and the Democratic Review in New York City at the center of the Young America Movement. In that sense, the movement can be considered mostly urban and middle class, but with a strong emphasis on socio-political reform for all Americans, especially given the burgeoning European immigrant population (particularly Irish-Catholics) in New York in the 1840s
