     Karl Marx was born on May 5th, 1818 in Germany. He went to high school and then continued

his studies at a university. He received his doctor's degree in April 1841.

     In 1842 Marx began writing articles for a newspaper. He wrote articles on many subjects. For

example, he wrote about housing problems of the poor people and the hard life of the peasants. He

started a new programme called "communism".This new kind of political idea was supported by the

working people, but hated by many governments. He and his wife had to move from one country to

another.

     During the 1840s, Marx met Engels, another revolutionary writer, and they became close friends.

Together they wrote The Communist Manifesto. It closed with words that quickly became famous:

"Working people of all countries, unite!"
