José da Costa Carvalho, Marquis of Monte Alegre, (7 February 1796 – 18 September 1860)[2] was a Brazilian politician, judge, journalist and magistrate.

In 1839, three years after the death of Geneva, José da Costa Carvalho married Maria Isabel de Sousa Alvim.

After finishing his studies in Portugal, he returned to Brazil and pursued a career as a magistrate in Salvador, until he was later appointed to the positions of Juiz de Fora and Ouvidor in São Paulo (1821–1822).

He served for a year in São Paulo, and then was elected in 1823, deputy for the province of Bahia, to the National Constituent and Legislative Assembly of the Empire of Brazil.

As it was unable to control the political and social upheaval the country was experiencing, after three months the General Legislative Assembly appointed a Permanent Triune Regency.

Senators and Assembly members voted jointly to appoint Francisco de Lima e Silva, João Bráulio Muniz and José da Costa Carvalho as the three regents.

Carvalho founded, ran and edited pt:O Farol Paulistano,[2] the first periodical printed and published in São Paulo, which circulated between 1827 and 1832.
