The Iron Lady.

Almost everyone in this world knows her.

She was the Prime Minister of Great Britain for more than a decade, re-transformed it to a powerful industrialized country. She remained close relationship with the United States that ended the cold war with the Soviets. She even brought the country into war with Argentina in 1982 if I'm not mistaken to regain Falkland.

She was a determined leader. She changed the atmosphere of the political world and also, the economy. Many might not agree with the decisions made during her era, but no one could ever deny her successful, iconic and impressive achievement that she had brought. She is truly a legend, a titan of the modern world, she is indeed, The Iron Lady.
She will be remembered. 

Margaret Thatcher, 1925 - 2013.
