The Mocidade was founded on 10 November 1955, by eight people: Silvio Trindade, Renato da Silva, Djalma Rosa, Olímpio Bonifácio, Orozimbo de Oliveira, Garibaldi F. Lima, Felipe de Souza, Ary de Lima e Alfredo Briggs. The first flag of the school was offered by Mrs. Gilda Faria Lima. The first queen of the school was Mrs. Neuza de Oliveira. The samba school participated for the first time, in an official parade, with the plot "O Baile das Rosas", when it got 5th place. In 1958, it was the champion of Group 2 with the plot "Apoteose ao Samba". From 1959 forth, it took on Group 1 and did not anymore any relegation to the lower divisions. In 1959, the bateria, under the expert Master André, gave for the first time the famous "paradinha" in front of the judging committee, maintaining the rhythm so that the school would continue developing. The folk would pass, later, to accompany such "bossa" with the shout of "Olé". During this period, the Mocidade was known as "a bateria that carried a school on its back", because the bateria was more known than the school itself, that only years later would become a school that would compete with the famous of that epoch. In the year of 1974, Arlindo Rodrigues presented the plot "A Festa do Divino", getting 5th place. But on that same year the school could win the championship, had she not gotten 4 in clothings and 9 in harmony. The difference between Salgueiro and Mocidade was 6, therefore they would have tied only if Mocidade would have gotten 10. Even if they would tie, Salgueiro would win the championship because it got 10 in harmony. From then on, the school stopped being known only because of the bateria, and became known as a good samba school. In 76, by irony, Mocidade tied second place, with Mangueira, and lost the decision for getting one point less in the so famous bateria. In 1979, still with Arlindo Rodrigues, Mocidade conquered for the first time the championship of the 1-A Division with "O Descobrimento do Brasil" in its debut appearance. Next year, Fernando Pinto assumed the post of carnival producer and director, producing exceptional carnivals in Mocidade and becoming known as the most creative and ingenious carnival producer ever known. In Fernando Pinto's first year in Mocidade, in 1980, the school conquered second place with the plot "Tropicália Maravilha". In 1983, Mocidade received the banner of the best communication with the public with the plot "Como era verde o meu Xingu". In 1984 it became the Madrinha to the London School of Samba, the first samba school to be established in the UK. In 1989, Mocidade visited London to perform at the 3rd European Samba Encontro and formally adopt the LSS. It advanced to the Special Group in 1990, and won three general championships since then. after years away from Champions Parade in youth gave a back on top, with a beautiful tribute to Morocco however in the final voting ended with vice-championship, which ratified title, due to error of a magistrate who used the Book Abre-Alas wrong. With this surprise the Mocidade Independente samba school thus won its fourth championship title, shared with Portela.
