Some political movements have aimed to change government policy, such as the anti-war movement, the ecology movement, and the anti-globalization movement. Many have aimed to establish or broaden the rights of subordinate groups, such as abolitionism, the women's suffrage movement, the civil rights movement, feminism, gay rights movement, the disability rights movement, or the inclusive human rights movement. Some have represented class interests, such as the Labour movement, socialism, and communism, others have expressed national aspirations, such as anticolonialist movements, Ratana, Zionism, and Sinn Féin. Political movements can also involve struggles to decentralize or centralize state control, as in anarchism, fascism, and Nazism. With globalization, global citizens movements may have emerged. Movements may be named by outsiders, as with the levellers political movement in 17th century England was so named as a term of disparagement. Yet admirers of the movement and its aims later came to use the term, and it is the term by which they are known to history.
