Jorge Zagaia, born Jorge Isidoro Da Silva in 1922 in Rio de Janeiro, Brazil, was a prominent Brazilian samba singer and songwriter. He was a foundational figure in the Mangueira samba school, one of the most famous samba schools in Brazil. Zagaia was instrumental in establishing the Ala dos Compositores da Mangueira and served as a support singer for the school's samba-enredo performances. He was known for his role as a partideiro, a style of samba performance characterized by improvised verses, and was closely associated with other samba luminaries such as Aniceto do Império and Xangô da Mangueira.

Throughout his career, Jorge Zagaia contributed significantly to the success of Mangueira, with the school winning several championships with his compositions. One of his notable works, "Casa Grande e Senzala," co-authored with Comprido and Leléo, was featured in Mangueira's 1962 parade and later included in Leci Brandão's 1976 album "Questão de Gosto." In 1989, Zagaia was part of the Velha Guarda da Mangueira and participated in the album "Mangueira Chegou," which was produced for the Japanese market. His compositions, such as "A Vida do Trabalhador" and "A Mangueira Não Morreu," were highlighted in this collection.

Zagaia's legacy continued posthumously, with his works being featured in various compilations and tributes. In 1998, the song "A Mangueira Não Morreu" was interpreted by Chico Buarque and Nelson Sargento in the album "Chico Buarque de Mangueira." Additionally, in 2000, his compositions were included in the "Mangueira - Sambas de Terreiros e Outros Sambas" CD produced by the Arquivo Geral da Cidade do Rio de Janeiro.

Beyond music, Jorge Zagaia worked as a public servant for the City of Rio de Janeiro, retiring in a leadership position. He passed away in 1995 in his hometown of Rio de Janeiro, leaving behind a rich legacy in the world of samba.
