Final answer:
A historical figure or a group leader would typically call a meeting of all the families or groups involved in a conflict to establish a truce. Such instances range from Jefferson Davis addressing rioters to precolonial town elders convening community gatherings for consensus.
Step-by-step explanation:
The question is regarding a historical moment where a meeting is called to establish a truce between groups, which could be political entities, gangs, or factions within a society. The general concept of calling a meeting for truce amongst conflicting parties has been a common practice throughout various periods of history, prevalent from precolonial times to more modern urban settings. Throughout history, leaders or influential individuals have often taken the initiative to convene such meetings with the goal of reaching a peaceful consensus or to quell disturbances. This could be seen in various situations such as the Confederate President Jefferson Davis handling a situation by offering sympathy and aid or resorting to threats to restore order during a riot, or community elders in precolonial Igbo societies summoning a general town meeting to reach consensus on issues and maintain peace.
