The municipality is named for the engineer and politician Benjamin Constant Botelho de Magajhães (1836-1891).
Benjamin Constant entered the Military College in Rio de Janeiro in 1852. As a professor of mathematics, he was introduced in 1857 to scientific positivism by the "Traité de géométrie analytique" and the first volumes of the "Cours de philosophie positive" published by the French philosopher Auguste Comte. In 1867, he campaigned for Comte's Religion of Humanity. Constant was among the founders of the Rio de Janeiro Postivist Society on 1 April 1876, which he left in December 1881.
In 1887, Constant, member of the Military Club, asked the club's president, General Deodoro de Fonseca, to publicly supported the abolition of slavery. This resulted in a petition to Princess Isabel asking the armed forces not to be commissioned to capture fleeing slaves.
In spite of being an "unfaithful and incomplete" positivist, Constant efficiently contributed to the positivist transition from the Empire to the Republic in 1889. He understood that the military uprising, aimed at overthrowing the decadent Imperial regime, was in search of an ideological support. Accordingly, the Republic of the United States of Brazil was pacifically proclaimed on 15 November 1889. Constant was appointed Minister of War by Deodoro de Fonseca, head of the provisory government.
