A more thorough explanation:

A body politic is a group of people who are organized under a common government. This group is seen in a political sense rather than a private one.

For example, a country's citizens can be considered a body politic. They are organized under a government and are subject to its laws and regulations. Another example is a corporation, which is also a body politic. The employees and shareholders are organized under a common authority, the board of directors.

These examples illustrate the definition of a body politic because they show how a group of people can be organized under a common authority for political purposes. The government or authority has the power to make decisions that affect the group as a whole, and the members of the body politic are subject to those decisions.
