Final answer:
Territorial disputes are a driving factor of conflict historically, fueled by competition for scarce resources and the desire for power, wealth, and cultural dominance.
Step-by-step explanation:
The issues that have historically driven conflict are often related to the competition for scarce resources, the quest for power and wealth, and cultural discord. Territorial disputes arise from the desire to gain or protect land and resources, while cultural harmony often falls victim to powerful personalities and divisive political forces. In the context of the original question, territorial disputes are a correct answer as they have consistently been a fundamental cause of conflict throughout history. This is exemplified by historical events such as the colonization efforts of European powers and internal conflicts like the French Revolution, where the control and division of territory were central issues.
