William Shakespeare,the greatest English playwright, 
was born in 1564 in Stratford-on-Avon in England.  Stratford is a small country town in a farming district near the centre of England .the Avon, which is a 
pretty river with  grass and trees all along its banks, 
runs through Stratford. Not much is known of Shakespeare's father. He was a farmer who, at different times of his life, sold meat and bought and sold 
wool. He was poor and was often in money difficulties. 
Very little is known about the life of his only son William 
also the little house in which the great writer was born 
still stands. It is now a museum. William went to
school in Stratford. In 1586 he went to London. 
Probably the first work he did there was at one of the two 
theatres that there were in London at that time. Then 
he became an actor and soon began to write plays for the 
company of actors to which he belonged. Shakespeare 
bought the largest house in his home town in 1597, but 
he did not spend much time there till 1610. He spent the 
last years of his life in it.
