The act of breaking up or dissolving a group, organization, or military unit so members go their separate ways.
From dis- (opposite) + band (from Old French bande, 'group'). The verb band meaning 'to gather' became disbanding by the 17th century in military contexts.
Disbanding carries historical weight — armies, bands, and political movements all 'disband,' and the word shows how groups that came together must eventually come apart.
