Answer :
In Machiavelli's "The Prince," the text evidence that supports his primary purpose to persuade readers that a conquering prince must destroy a former republic if he hopes to hold it includes:
1. The explanation of how Rome held Capua, Carthage, and Numantia: Machiavelli illustrates how the Romans successfully retained control over these cities by dismantling them, thus preventing any potential rebellions. This serves as an example of the necessity to destroy former republics to maintain power.
2. The description of liberty as a rallying cry for rebellion in former republics: Machiavelli emphasizes that liberty and ancient privileges become rallying points for rebellion in cities accustomed to freedom. This highlights the challenge a conquering prince faces in holding a republic without eliminating these sources of resistance.
3. The example of the Florentines losing control over Pisa: This example demonstrates the consequences of not taking decisive actions to control a former republic. By showcasing how the Florentines lost control over Pisa due to not destroying it, Machiavelli reinforces the idea that a conquering prince must be willing to dismantle former republics to prevent future uprisings.
By using these elements from the text, Machiavelli conveys his argument that a conquering prince must resort to destruction and dismantling of former republics to ensure long-term control and stability.
