A sense of belonging to a larger political group, such as a party, a social movement, or a particular political movement. This affiliation reinforces people’s shared identity, their commitment to the group’s values and policies, and motivates collective participation in political life, including campaigning, community mobilization, and advocating for the group’s positions in public debate. Belonging to a group also contributes to the formation of strong social ties that support the political effectiveness and internal stability of the group.
