Teachers' Day is observed in Brazil every October 15, celebrating the vital role of teachers and their contributions to national development. This date holds historical significance as it marks the anniversary of a decree signed by Emperor Pedro I in 1827, which established primary schools for the lower class, making education accessible to all societal layers. The first celebration of Teachers' Day took place in 1947, initiated by teachers at a small school in Rua Augusta, who organized a parade to honor education and curriculum planning. This tradition quickly spread to other schools across Brazil, leading to the holiday gaining official status in 1963. The observance recognizes the importance of education and the dedication of teachers in shaping future generations.
