Suzan Shown Harjo (70) has been campaigning for the rights of Native Americans for over 40 years. In the late 1970’s the then US President Jimmy Carter appointed her to the post of official point of contact between the US Government and the Native American community.

Two years ago President Obama awarded her the Presidential Medal of Freedom. In a series of court cases Ms Harjo has succeeded in getting back large swaths of land for her people.

She has also campaigned against sport clubs, such as the Washington Redskins, that to her mind have degrading images of Native Americans in their logos.

Of the three thousand teams she has contacted over two thousand have changed their logo, name or mascot.
