Hopkinson was the author of several songs to which he wrote popular airs, and of various political poems, pamphlets, and jeux d'esprit, which from their humorous satire had a wide circulation, and powerfully asssisted in arousing and fostering the spirit of political independence that issued in the American Revolution.
His principal writings are The Pretty Story 1774; The prophecy 1776; The Political Catchism 1777. Among his songs may be mentioned The Treaty, The Battle of the Kegs, and The New Roof, a song for Federal Mechanics; and the best known of his satirical pieces are Typographical Method of conducting a Quarrel, Essay on White Washing, and Modern Learning. His Miscellaneous Essays and Occasional Writings were published at Philadelphia in three volumes in 1792.
He died in Philadelphia.
