Deixa Falar was the earliest samba school. The group was initiated in Rio in 1926. The first competition began a few years later. The judging criteria was created in 1932 and has been revised over time. The original schools were sponsored by football teams. Now they are predominately neighborhood organizations, often times from impoverished areas called a favela. Since 1984, the parades have been conducted at the Sambadrome. There is a fierce loyalty to certain schools, especially those with a long track record of championships.
