U.S. politician.
From 1834 he served in the Rhode Island legislature, where he tried to introduce constitutional reform to expand white manhood suffrage. In 1841 he organized the People's Party, which held elections and installed Dorr as governor in 1842. The existing government refused to recognize his authority, labeling the action "Dorr's Rebellion." The state had two governments until 1844, when Dorr was tried for treason; though given a life sentence, he was released in 1845.
