Han nationalism is the nationalism that asserts that the Hans are a nation, and promotes the cultural uniformity of the Hans. It is built upon various right-wing ideologies and sentiment; a syncretic blend elements emanating from the traditional socio-political philosophies of Confucianism and Legalism, as well as imported political philosophies such as Japanese statism, American exceptionalism, and Soviet statolatry. It is regarded as a type of ethno-cultural nationalism, deemphasizing and trivializing matters such as allegiance or citizenship (as in civic nationalism) while emphasizing the adoption of the Han ethnic identity and culture. It has been promoted by the Han government under the basis of promoting political unity and patriotism, launching active campaigns to curb regionalism, separatism, and multiculturalism. It is often used in its struggle to fulfil the ideals of the Han Dream, and thereby justify its authoritarian and heavy-handed government.
Since its establishment during the laxity of the Roaring Twenties, its growth in popularity during the reestablishment of colonial rule during the thirties and policies bent on the suppression of Han culture, it and the Han Nationalist Party have been often criticized. Vocal critics include Han diaspora living in Sierra, who are descendants of political émigrés, as well as ethnic minorities who receive discrimination for resisting and refusing to conform under its beliefs. Han nationalism is often credited by some political analysts as reasons for an increasing authoritarian state, and a rise in human rights violations including persecution of religious minorities, usage of police brutality, and censorship.
