in 1965, the federação dos blocos carnavalescos do estado do rio de janeiro - fbcerj (federation of carnival blocks of rio de janeiro) is also created.

the federation to this day regulates the competition among the blocos de enredo, or thematic blocks - these blocks specifically compete against one another to be promoted to the status of samba schools.
