What was Dadaism?

Marcel Duchamp's
Mona Lisa

A protest against World War I
Was known as Dadaism
It was started by creative types
Angry at nationalism
They regarded this as one vital part
To the beginning of the War
So a cultural movement was launched
With anger at its core
French and German creatives
Banded together to provoke
From their base in Zurich
Many emotions did they evoke
Marcel Duchamp was part of the movement
He liked to vandalise art
Like drawing a moustache on Mona Lisa

Tristan Tzara's
Dadai

And scrawling an obscene remark
Tristan Tzara was another member
He wrote a book about it all
It was called Dadai
And he would read from it wearing a monocle
Parts of Europe and America
In time followed suit
But some people were repulsed
And would have preferred them to stay mute
It began in 1916
Continuing for six years
But when mainstream art started taking notice
Dadaism died and disappeared
