Insurgents, in U.S. history, the Republican Senators and Representatives who in 1909–10 rose against the Republican standpatters controlling Congress, to oppose the Payne-Aldrich tariff and the dictatorial power of House speaker Joseph G. Cannon. Many—but by no means all—of them joined the Progressive party.
