Queen Elizabeth I who reigned from 1558 to 1603 was one of the most successful monarchs to
rule England. Born to King Henry and his second wife Anne Boleyn couldn’t give him a male heir
(наследника), Henry beheaded Anne so that he could marry again. He sent Elizabeth away to the
country where she was brought up by governesses.
Her stepbrother Edward, who became king at the age of 9 after King Henry died, also died at 15.
However, Elizabeth had an older stepsister, Mary, who became the heir. Mary was afraid that Elizabeth
was trying to take her throne, so she imprisoned her and later placed her under house arrest for many
years. The people of England often called the Queen “Bloody Mary”, they were afraid of her and they
were happy when in November 1859 she finally died, naming 27-year-old Elizabeth the new Queen of
England.
During her 44-year reign Elizabeth showed great leadership transforming what was a poor weak
island into a wealthy European country. Also, thanks to her love for music, drama and poetry, she
encouraged artists and writers. She supported some of England’s greatest writers including William
Shakespeare
