Who were the Tertium Quids?
The term was first used in Pennsylvania in 1804, referring to a faction of the Democratic-Republican party called "the Society of Constitutional Republicans." They gathered Federalist support and in 1805 re-elected Governor Thomas McKean, who had been elected by a united Republican party in 1802 but had broken with the majority wing of the party. In New York state the term "quid" was applied to the Republican faction that remained loyal to Governor Morgan Lewis after he was repudiated by the Republican majority led by DeWitt Clinton. The two "quid" factions had no connection with each other and there was no third party at the federal level, for the quids supported President Thomas Jefferson.
