this big group, dubbed g. r. e. s. grande rio, would later combine with the acadêmicos de caxias school to further centralize the potential of all the creative teams involved.

this would create the school today known as g. r. e. s. acadêmicos do grande rio, at the time still part of the third division of the samba school hierarchy.

the results of these fusions were quick to take effect and, after the first participation of this new organization, in 1989 it would immediately ascend to the second division.

during the 1990s and 2000s the school created several successful parades, which reinforced its fame as one of the greatest among its peers.
