Use the passage to answer the question the Georgia governors order is an example of which of the following
My answer was marital law, but the correct answer was sectionalism Can you explain to me why my answer was wrong and the other answer was correct

Your answer of martial law is incorrect because martial law refers to the imposition of military control over civilian populations. In this passage, the governor of Georgia insisting that only Georgia officers should command Georgian troops is not an example of martial law.

The correct answer, sectionalism, is a better fit for the situation described in the passage. Sectionalism refers to loyalty or support for a particular region or section of a country, often at the expense of national unity. In this case, the governor of Georgia is prioritizing the interests of his own state (Georgia) over those of the central government (the Confederacy), demonstrating a sectional bias. This reflects the political problems faced by the Confederacy, where states' rights were favored over central authority, leading to difficulties in central governance.
