CUNHA BARBOSA, Januario da (koon'-yah bar-bo'-sa), Brazilian statesman, born 10 July 1780; died 22 February 1846. He was chaplain of John V[., and afterward professor of moral philosophy. On 15 December 1821, he established, in conjunction with Ledo, the "Reverbero Constitucional," a political journal, at Rio de Janeiro, favoring Brazilian independence. After this had been declared, Cunha was arrested, 7 December 1822, and banished to France. To repair this injustice, he was appointed in 1824 canon of the imperial chapel. In 1826 he became a member of the assembly. In concert with General Cunha, he founded the Historical and geographical society of Rio de Janeiro. He also edited a political journal favorable to the government, and an agricultural paper, and was imperial historiographer and director of the national library. He left a small volume of poems.
