Pablo Picasso is well known as one of the most famous artists of the 20th century. His name is virtually synonymous with the term Modern Art. During his 75 year career, he created thousands of paintings, prints, and sculptures. His influence on the art of th 20th century is undisputed, and he has been recognized as the greatest art genius of the twentieth century.
He was also an active, thoughtful and expressive Communist.
"Communism for me is closely bound up with my entire life as an artist," Picasso said. And in a 1954 interview, "I am a Communist and my painting is Communist painting."
From the article Picasso: Peace and Freedom:
In a visually sophisticated age, Picasso often used Cubist space and Expressionist distortion and simplification to express feelings and ideas. But at a time when Western critics argued that the only "advanced" painting was abstract, he resolutely continued making representations of the visible world. Sometimes gently, often fiercely, always directly, he condemned oppression, cruelty and bigotry, celebrated life and humanity and called for justice, peace and freedom.
