The Center's best known work is our 30 years of organizing and advocacy to win adoption of the UN Declaration on the Rights of Indigenous Peoples. The Declaration was adopted by the UN General Assembly in 2007. The Declaration proclaims an historic body of collective rights and human rights of indigenous peoples and individuals. For the first time in history indigenous peoples' right to exist was declared to be a legal right. The Center continued its leadership in seeking endorsement of the declaration by President Barack Obama's Administration, and in 2010, the United States officially endorsed the UN Declaration. The Center staff continues to educate government officials, tribal leaders and non-governmental organizations about the Declaration and continues to advocate measures at the national and international levels to implement the principles of the Declaration.
