White nationalism is a type of nationalism or pan-nationalism which espouses the belief that white people are a race and seeks to develop and maintain a white racial and national identity. Its proponents identify with and are attached to the concept of a white nation. White nationalists say they seek to ensure the survival of the white race, and the cultures of historically white states. They hold that white people should maintain their majority in majority-white countries, maintain their political and economic dominance, and that their cultures should be foremost. Many white nationalists believe that miscegenation, multiculturalism, immigration of nonwhites and low birth rates among whites are threatening the white race, and some believe these things are being promoted as part of an attempted white genocide.
