Understanding Jure Sanguinis: The Legal Basis for Citizenship by Descent in Europe
At Pravas Global, we specialize in helping individuals navigate the complexities of acquiring European citizenship through jure sanguinis, or citizenship by descent. This legal concept, rooted in the principle of bloodline rather than residency or birthplace, offers a unique pathway to citizenship across various European countries. Understanding the legal basis for jure sanguinis requires a comparative analysis of how different nations implement this principle.
The Principle of Jure Sanguinis
Jure sanguinis, Latin for “by right of blood,” allows individuals to inherit citizenship through their parents, grandparents, or sometimes even more distant ancestors. This concept contrasts with jure soli, or citizenship by birth on the territory of a country. While jure soli is more prevalent in countries like the United States, many European nations favor jure sanguinis, emphasizing the importance of familial ties and national heritage.
Country-Specific Examples
Italy
Italy is renowned for its jure sanguinis provisions, allowing citizenship to individuals with Italian ancestry. The Italian Citizenship Law of 1992 grants citizenship to descendants of Italian citizens, irrespective of the generation, as long as the lineage is unbroken. This means that even those whose ancestors emigrated centuries ago can apply, provided they meet specific conditions, such as the ancestor not having renounced their citizenship, in addition to meeting various cut-off dates.
Germany
Germany also recognizes jure sanguinis, but with a more restrictive approach. Under the Nationality Act, children born to at least one German parent are granted citizenship, regardless of their place of birth. However, the law also stipulates that individuals seeking citizenship through a grandparent must meet certain criteria, such as proof of the grandparent’s citizenship status and maintaining ties to Germany. Citizenship on the basis of great-grandparents or great-great-grandparents is also possible in some cases. In addition, descendants of individuals persecuted for their religious or political beliefs by the National Socialist regime have a simplified path to citizenship.
Croatia
In addition to its stunning coastlines, Croatia also has arguably the most flexible citizenship by descent policy in the European Union. Interestingly, citizenship is generally open to descendants of emigrants from present-day Croatian territory (of any ethnicity) and ethnic Croats. There is no language requirement for citizenship by descent under Croatia’s citizenship law. If you have Croatian roots, you most likely qualify!
Hungary
In Hungary, citizenship by descent allows individuals to claim Hungarian citizenship if they can prove their ancestry, typically through parents or grandparents. This principle is codified in the Hungarian Citizenship Act, enabling those with Hungarian heritage to reconnect with their roots. Additionally, simplified naturalization is available for ethnic Hungarians living outside Hungary, further descendants of Hungarian emigrants, or descendants of emigrants former Hungarian territories, allowing them to obtain citizenship more easily. This process typically requires proof of Hungarian ancestry, language proficiency, and an affirmation of loyalty to Hungary. These provisions reflect Hungary’s commitment to supporting its diaspora and preserving cultural ties.
Ireland
Ireland’s approach is similarly favorable towards jure sanguinis. Irish citizenship is available to anyone with at least one grandparent born in Ireland. This law reflects Ireland’s historical migration patterns and the significant Irish diaspora worldwide. The process is straightforward, requiring proof of lineage, such as birth certificates and marriage records.
Poland
Poland offers a unique perspective on jure sanguinis, where citizenship can be claimed by descendants of Polish citizens who lost their citizenship due to historical events, such as World War II. The law allows for claims to citizenship by those who can trace their lineage back to a Polish ancestor, but the process may involve proving the ancestor’s citizenship status at the time of emigration.
Austria, Slovakia, Portugal, Luxembourg, Ukraine, and Serbia
Whilst out of this article’s limited scope, these countries all have forms of citizenship by descent. If you have ancestry from any of these countries, contact us to learn more! Note that Ukraine and Serbia are currently not EU member states.
The Importance of Documentation
Regardless of the country, applicants must provide thorough documentation to establish their lineage. This typically includes birth, marriage, and death certificates, all of which must clearly illustrate the familial connections leading to the applicant’s ancestor. The requirements can vary significantly, making expert guidance essential.

Frequently Asked Questions (FAQ)
Do I have the right to live in the UK as an EU citizen?
No, the UK left the EU in 2020. With the exit of the UK from the European Union, EU citizens unfortunately lost the freedom of movement in the UK. Nevertheless, EU citizens still have the freedom of movement in over 30 countries, including neighboring Ireland.
How many citizenships can I have?
Contrary to popular belief, most countries do not have a maximum number of citizenships permitted per se. Furthermore, “dual citizenship” is not a legal institution itself, rarely mentioned by national legislation, but rather a mere description of the legal phenomena of having more than one citizenship. The acquisition and loss of each country’s citizenship is regulated by the respective country’s legislation.
How long does the citizenship procedure take?
The timeline depends on your specific case and the specific administrative authorities involved.
As a dual citizen, will I need to pay taxes in the EU?
The United States is one of the only countries in the world that taxes on the basis of citizenship. European Union member states take a more residency-based approach to taxation. Generally, some kind of substantial link will need to be created between the citizen and the country other than citizenship, such as residence, either administratively or through physical-presence. Pravas Global does not current provide tax consulting services and does not advise on tax law.
