The Memphis Eagle was founded in 1842 as a weekly Whig paper known as the American Eagle. Its chief rival was the Democratic-leaning Memphis Appeal. In late 1842 the paper began putting out a daily paper, the Memphis Eagle, while continuing the weekly American Eagle. The weekly paper was a compilation of articles that appeared in the daily paper. For that reason, indexing was switched to articles in the daily Memphis Eagle in 1846. In late 1851 the Eagle merged with the Memphis Enquirer to become the Memphis Eagle-Enquirer.
