if modern rio de janeiro's carnival is defined by as the presence of distinct blocos and samba schools parading, then this is when modern carnival in rio was born.

as rio de janeiro entered the 1930's, a strong nationalistic culture was permeating brazil, and the blocos changed into the blocos as they are known today.

men and women, the rich and the poor, the young and the old, side by side, marching in unison through the streets in costumes, often satirizing the political class, and applauding carioca history and traditions.

blocos are now a group of people marching freely in the streets, in costumes, at the sound of music in a group that was considered less elitist than a rancho, and more proper than a cordão.
