Final answer:
The Kurds, Rohingya, and Palestinians are three stateless nations with distinct cultural identities but without sovereign territory or a nation-state.
Step-by-step explanation:
Three stateless nations (peoples) in the world include the Kurds, the Rohingya, and the Palestinians. Stateless nations are those that have a distinct culture and history but no sovereignty over a specific territory. For example, the Kurds are a large ethnic group spread across regions in Turkey, Iraq, Iran, and Syria yet do not have a country of their own. The Rohingya are an ethnic group facing persecution in Myanmar, leading to a significant number of them becoming refugees. The Palestinians have been in conflict with the State of Israel since its establishment, resulting in many Palestinians living in refugee camps without a recognized sovereign state.
