The term neo-Nazism describes any post-World War II militant, social or political movements seeking to revive the ideology of Nazism in whole or in part.[4][5]
The term neo-Nazism can also refer to the ideology of these movements, which may borrow elements from Nazi doctrine, including ultranationalism, anti-communism, racism, ableism, xenophobia, homophobia, anti-Romanyism, antisemitism, up to initiating the Fourth Reich. Holocaust denial is a common feature, as is the incorporation of Nazi symbols and admiration of Adolf Hitler.
