Diplomatic rank is like a job title, but for people who work in government offices and embassies. Diplomats are government officials who represent a country, and they hold different levels of responsibility and authority. Each diplomatic rank is a different title, and some levels are more important than others. Generally, the higher the level of diplomatic rank, the higher the level of responsibility and authority a person has. For example, ambassadors are the highest ranking diplomats and they usually serve as a country's top representative in another country.
