National Alliance was a national conservative political party in Italy. It was the successor of the Italian Social Movement (MSI), a neo-fascist party founded in 1946 by former followers of Benito Mussolini that had moderated its policies over its last decades and finally distanced itself from its former ideology, a move known as post-fascismo, during a convention in Fiuggi by dissolving into the new party in 1995.

The Italian Social Movement was a neo-fascist political party in Italy. A far-right party, it presented itself until the 1990s as the defender of Italian fascism's legacy, and later moved towards national conservatism. In 1972, the Italian Democratic Party of Monarchist Unity was merged into the MSI and the party's official name was changed to Italian Social Movement – National Right.
