A group of people or nations controlled by an emperor is an empire.

In order to answer this question, we need to understand the definitions of the options provided.

1. City: A city refers to a relatively large and permanent human settlement with an organized government and inhabitants who engage in non-agricultural activities such as trade, industry, and administration. However, a city does not necessarily imply a system of government controlled by an emperor.

2. Empire: An empire is a group of people or nations that are brought under the control of a single ruler or ruling entity, usually an emperor. It is characterized by its extensive territorial holdings, often encompassing multiple regions or countries.

3. Village: A village is a small community or settlement, typically located in rural areas, consisting of a few houses or dwellings. Villages are generally organized around agricultural practices and do not have the political structure required for an emperor to rule over them.

4. Civilization: A civilization refers to a complex human society characterized by advanced social, cultural, economic, and political development. While civilizations can have various forms of governance, including empires, not all civilizations are controlled by an emperor.

Based on the definitions provided, the option that best fits the description of a group of people or nations controlled by an emperor is "empire." An empire typically involves a centralized authority led by an emperor who exercises political and military control over its territories and subjects.
