The observation of National American Indian Heritage Month has its roots in Public Law 99-471. Over several years the observation was moved to different months but in 1990 Public Law 101-343 set the month long observance in November. Each year the President issues a Proclamation in recognition of the observance. National American Indian Heritage Month is observed from 1 – 30 November of each year. The observance month recognizes American Indians for their respect for natural resources and the Earth, having served with valor in our nation’s conflicts and for their many distinct and important contributions to the United States.
