What is considered a major cause of civil unrest during the revolution?

Civil unrest during a revolution often arises from deep-seated divisions within society regarding the revolutionary changes taking place. In this context, option C highlights how differing views on the direction of the revolution can lead to conflict among various social groups. Some may support the revolutionary ideals, while others may resist changes that threaten their status, beliefs, or way of life. This discord can manifest in protests, riots, and other forms of civil unrest, as factions within a society clash over their vision for the future.

Economic stability, while often linked to social contentment, typically does not drive unrest; instead, a lack of economic stability can exacerbate tensions but does not inherently represent a cause of civil unrest. The nationalization of church properties may contribute to unrest but is a more specific issue within the broader context of societal divisions. Support for the restoration of monarchy usually suggests a desire to revert to old systems rather than an immediate cause of unrest within the revolutionary framework, where debates about the nature of government are more pronounced. Thus, the division in society over revolutionary changes is the most significant catalyst for civil unrest during this period.
