In the state of Bahia in north east Brazil, in the last quarter of the 19th century, a city was founded by poor people who wanted to live in hope and comradeship. They wanted to live by the principals of Christian Communism, as described in the Acts of the Apostles. Their leader was Antonio Conselheiro. They founded a Commune that consisted of 5,200 homes and involved 24,000 people. Everybody who could work, did work. Money was not needed, as everyone took what they really needed, but, in comradely spirit, took no more. There was no need for police.
So, how did the ruling class take this Communist Utopia? They sent an army that burned every home to the ground, and slaughtered hundreds of people. They captured Conselheiro, and beheaded him in 1897.
Today, the ruling class claim that such a Utopia is impossible. They say that human beings are naturally greedy and egotistical and could never live in peace and comradeship. As the people of Canudos showed in the 19th century, and the Zapatistas show today, the ruling class are liars
