It is unclear which specific nation states are being referred to in the question. However, some of the earliest nation states in history include ancient Sumer, ancient Egypt, the city-states of ancient Greece, and the Gupta Empire in ancient India. Each of these can be considered as one of the first nation states established in their respective regions.

To determine which of the following nation-states was one of the first to be established, you would need to have a list of nation-states to choose from. Without that information, I cannot provide a specific answer. However, I can explain how you can conduct your own research to find the answer:

1. Start by gathering a list of nation-states that you want to investigate. This list could include historical nation-states or modern ones, depending on your research focus.

2. Conduct research using credible sources such as history books, academic journals, or reliable online sources. Look for information about the establishment of each nation-state.

3. Examine the historical context of each nation-state's establishment. Consider factors such as the development of central governments, the formation of distinct borders, or the emergence of national identities.

4. Cross-reference the information you find from multiple sources to ensure accuracy and reliability.

5. Analyze the data you have collected to identify which nation-states were among the earliest to be established.

By following these steps, you should be able to identify which of the listed nation-states was one of the first to be established.

One of the first nation-states established was the city-state of Sumer, located in ancient Mesopotamia. It emerged around 3000 BCE and encompassed several city-states such as Ur, Uruk, and Lagash.
