‘’William Shakespeare”
William Shakespeare, the greatest English writer of drama, was born in 1564 in
Stratford-on-Avon. We don`t know everything about his early life. 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. He soon became well-known in
London literary circles. Every play he wrote was good news to the people of the
capital. Queen Elizabeth I liked his plays and the actors were often invited to
perform before the Queen and later before the King James – a great honor in
those days. By the end of the 16-th century Shakespeare and his friends built
their own theatre –the famous Globe Theatre.
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.
Now people in many countries love and honor Shakespeare for his plays,
comedies and tragedies that are still modern and performed all over the world.
