1.William Shakespeare, the greatest English writer of drama, was born in 1564 in Stratford-on-Avon. We don’t know everything about Shakespeare’s early life. But we know that he studied at the Grammar School in Stratford, and that he became interested in the theatre when he was still a boy.

In 1586 Shakespeare went to London, where he worked in the theatre for some years before he began to write his own plays.

2.Shakespeare soon became well-known in London literary circles. Every play that he wrote was good news to the people of the capital. Queen Elizabeth I liked Shakespeare’s plays, and the actors were often invited to play before the Queen and later before the King James- a great honor in those days. By the end of the 16th century Shakespeare and his friends built their own theatre –the famous Globe Theatre.

3.But Shakespeare had many difficulties in his life. Less talented writers, whose plays were worse than his, often quarreled with Shakespeare and attacked him, the actors in his own theatre sometimes turned against him.

4.Now people in many countries love and honor Shakespeare for his plays, comedies and tragedies that are still modern and well-known all over the world.
