A more thorough explanation:

Ambasciator

Ambasciator is a historical term that means a person who is sent to represent someone else. This person is usually sent on important missions and is known as an ambassador.

During the Renaissance period, many Italian city-states sent ambasciators to other countries to negotiate trade deals and alliances. For example, the Republic of Venice sent ambasciators to the Ottoman Empire to negotiate a peace treaty.

In modern times, countries still send ambasciators to represent them in other countries. For example, the United States has an ambasciator to the United Nations who represents the country's interests in international affairs.

These examples illustrate how ambasciators are important representatives who are sent to other countries to negotiate on behalf of their country or organization.
