Perhaps the most famous poet of Russian futurism movement, Mayakovsky (born 1893) is particularly interesting for his powerful and original verse as well as his experiments in theater. One of his most famous poems of pre-revolutionary period is "Cloud in Trousers", here's an excerpt:
"You need –
I'll be crazy from meat
– like the sky that's changing the colours –
i'll be impeccably tender and neat,
not a man, but a cloud in trousers"
(translated by D. Paranyushkin)
After the Russian revolution (1917) Mayakovsky was leaning more towards propaganda of Bolshevik's beliefs (which he shared with full passion). However, towards the end of his life he became somewhat disillusioned with the system and his last poems bear a kind of criticism. He killed himself in 1930 officially because of unhappy love, but some researches believe that he was murdered by the order of Stalin.
