Davis has been seen as an early exponent in Ireland of what has since been understood as
cultural nationalism. In contrast to the
Painite republicanism of the 1790s, and to the mix of
Benthamite utilitarianism and Catholic devotionalism that characterised O'Connell's leadership of the national movement, Davis promoted the
Irish language as a means of reconnecting with the
Gaelic past. Davis drew inspiration from the civic and enlightenment ideas promoted by the
United Irishmen prior to the
1798 Rebellion. One of Davis's first major projects was a collection of the bar, and parliamentary speeches, with a "Memoir and Historical Notices", of
John Philpot Curran.
Karl Marx was to recommend it to
Friedrich Engels on the basis of being able to find there "quoted there all the sources for the
United Irishmen". Davis was also the source of a hagiography of The United Irishmen, centred on the figure of
Wolfe Tone. In 1843, he published his elegiac poem ''
Tone's Grave'', and with the blessing Tone's widow Mathilda (in American exile), organised the first
Bodenstown Tone memorial.'''' With for his fellow
Young Irelander (and Protestant)
John Mitchel, Tone for Davis was an "alternative national hero" to O'Connell, "the Liberator", with whose solicitation of Whig government favour and Catholic
clericalism he was increasingly at odds.'''' It was a turn toward a
romantic nationalism, in which Davis was influenced by the ideas of
Johann Gottfried von Herder (1744–1803). For Herder nationality was not genetic but the product of climate, geography, history and inclination. Davis did write of an "unsaxonised" Ireland, but this was not an Ireland ethnically cleansed of those of his own British ancestry and reformed religion. Rather it was an Ireland in which Catholic and Protestant alike, find sufficient unity and strength in their education and in their "recollections, ancestral, personal, national" to resist England's "unnatural", "cosmopolite" influence. ==Differences with Daniel O'Connell==
