Gundi is a classic case of balance of power in tribal areas. It is derived from Pashto word Gund, meaning a political party but it is used for an alliance. As modern states enter into bilateral agreements for promotion of trade, cultivation of friendly relations and mutual defence, similarly various sections of a tribe align themselves in blocs or Gundis to safeguard their common interests. Gundi is entered into defeat the aggressive and nefarious designs of a hostile neighbour. In tribal fighting the Gundi members espouse their mutual interests against their common enemy and act as a corporate body with all the resources at their command.
The history of the Pukhtoons provide many instances of long blood feuds spreading over several years. To quote an example, a quarrel of a few blacksmiths split up the Zarghun Khel section of the Adam Khel tribe into two warring factions in 1922 and the hostilities continued for over five years in which the tribesmen of different villages arrayed themselves on one or the other side. The member of a Gundi maintain constant liaison with each other, exchange views on matters of common interest and hold mutual consultations to meet critical situations. They invite each other on festive occasions, help each other in the hour of need and share each other's joys and sorrows.
