What is described as a state of disorder due to a lack of government?

The term that is best described as a state of disorder due to a lack of government is anarchy. Anarchy refers to a political philosophy or state where there is an absence of authority or a governing body, which leads to a breakdown in the structured rule of law and can create disarray and confusion among individuals. In such a situation, there might be no defined rules or systems of governance, resulting in chaotic conditions as people may act independently without a coordinated government to impose order.

While chaos is often associated with disorder, it does not inherently imply the lack of government; chaos can occur even within a governed context. Control is the opposite of what anarchy represents, as it implies the presence of authority or regulation. Order signifies a state of organized or structured society, which again is contrary to the concept of anarchy. Hence, anarchy is the only term that specifically encapsulates the idea of disorder resulting from the absence of a governing authority.
