South Korea's first female president who took office in February 2013. Before becoming president she served four consecutive parliamentary terms and was a member of Korean National Assembly.
In a country still very much gripped by patriarchy, she proudly campaigned on her gender, calling herself the first prepared woman president.
She found it difficult to escape from under the shadow of her father, first defending his controversial actions by saying the circumstances called for it, and then apologizing for the people he hurt.
She and Malala Yousafzai, another woman changing politics in the world, were both named among Time magazine's most influential people of 2013.
