A more thorough explanation:

Definition: The national government is the governing body that oversees an entire country, as opposed to the government of a specific province, state, or territory within that country. It is also distinct from international organizations.

Examples:

• The United States government is a national government that oversees all 50 states and territories.
• The Canadian government is a national government that oversees all provinces and territories.
• The government of France is a national government that oversees all regions within the country.

These examples illustrate the definition of national government by showing how it is responsible for governing an entire country, rather than just a specific region or subdivision within that country. National governments are responsible for making decisions and policies that affect the entire population, and they have the authority to enforce laws and regulations across the entire country.
