Elizabeth 2 is the Queen of Great Britain. She was born in Windsor on 21 April 1926. Her full name is Elizabeth-Mary-Alexander Windsor. Her pet name is Lilibet. She was educated at home, taught to read and write by her parents. She knew foreign languages. Elizabeth was made her speech on the radio in 1940. She was learned to drive. She was married Prince Philip in 1947. Her first son Prince Charles was born in 1948. She came to throne in 1952. Elizabeth was crowned in Westminster Abbey on 2 June 1953.
Now she plays an important role in the country. She travels a lot. The Queen has got four children: Prince Charles, Princess Anne, Prince Andrew, and Prince Edward. She has five official residences in Britain; Buckingham Palace and Windsor among them.
Queen Victoria was a strong queen. Her monument you can see in front of Buckingham Palace. Queen Victoria came to throne in 1837 and reigned until her death in 1901. She ruled for the longest period in the English history, for 64 years! Victoria married a German, Prince Albert, but he died at the age of 42 in 1861. That was a great tragedy for Queen Victoria. She left London and never lived in the city where she had been so happy with her husband and nine children (5 daughters and 4 sons). But there are places in London that reminds us of their love. One of them is the Royal Albert Hall - a very large concert hall where the best musicians of the world perform classical music. In front of the Albert Hall there is a monument to Prince Albert built by Queen Victoria. Another place is theVictoria and Albert museum (V & A) with its rich collections of paintings and other works of art. The family life of Queen Victoria touched people's hearts. But this is not only reason why Queen Victoria became very popular. During her reign Britain became a rich industrial country with a developed trade, an empire with a lot of colonies.
