The Modern Art Week (Portuguese: Semana de Arte Moderna) was an arts festival in São Paulo, Brazil, that ran from 10 February to 17 February 1922. Historically, the Week marked the start of Brazilian Modernism; though a number of individual Brazilian artists were doing modernist work before the week, it coalesced and defined the movement and introduced it to Brazilian society at large.
The Week took place at the Municipal Theater in São Paulo, and included plastic arts exhibitions, lectures, concerts, and reading of poems. In its breadth it differed significantly from the Armory Show, with which it is often compared, but which featured only visual art. It was organized chiefly by painter Emiliano Di Cavalcanti and poet Mário de Andrade, in an attempt to bring to a head a long-running conflict between the young modernists and the cultural establishment, headed by the Brazilian Academy of Letters, which adhered strictly to academicism. The event was controversial at best and divisive at worst, with one member of the Academy, Graça Aranha, ostracized for attending. He had opened the week with a conference titled "The aesthetic emotion in modern art". Due to the radicalism (for the times) of some of their poems and music, the artists were vigorously booed and pelted by the audience, and the press and art critics in general were strong in their condemnation (such as in a famous episode by editor, writer and art critic Monteiro Lobato).
