Political Persecution
Some countries offer citizenship to descendants of those who fled persecution. For example, Germany has programs for descendants of Nazi regime victims, and several European countries have provisions for those who lost citizenship due to political persecution.
Religious & Cultural Heritage
Some countries have programs for descendants of historically displaced religious groups. For instance, Portugal and Spain offer paths based on cultural heritage and language connections, helping descendants maintain ties to their ancestral homeland.
Territory Changes
Several European nations maintain citizenship routes connected to former territories. The UK, France, and Netherlands, for example, have provisions for regions that changed sovereignty through history.
