The following is a list of European countries that recognize citizenship based on ancestry that grant citizenship for up to 3, 2, or 1 generation:

You can now apply for citizenship by ancestry up to the third generation in Bulgaria according to recent amendments to the country’s citizenship laws. If your parents, grandparents, or great-grandparents were Bulgarian citizens, you can apply to become a citizen of the country.
Additionally, the application procedure for citizenship by descent from Bulgaria is now easier to access. Along with submitting your application, you must present documentation demonstrating that your ancestors were Bulgarian nationals. A response could come up to 24 months later.
CroatiaIf you have a parent, grandparent, or great-grandparent who has or possesses Croatian citizenship, you can gain it by descent. However, you are ineligible for citizenship by descent if your ancestor left Croatia before 8 October 1991 and migrated to another nation in the former Yugoslavia.
You have until the age of 21 to register in the civil registration if you were born to Croatian parents abroad (in the event your parents did not record your birth, and you want to apply for citizenship in Croatia.)

Another EU nation that permits citizenship by descent through the third generation is Greece. You may be eligible for Greek citizenship through ancestry if:

Compared to other EU nations, Hungary has a slightly different citizenship by descent law. The biggest benefit of Hungarian citizenship rules is that everyone who can speak Hungarian and has a Hungarian ancestor in their family is eligible to become a citizen.
Therefore, as long as you can show you have a Hungarian ancestor in your direct line, there is theoretically no restriction on how far back in your family tree you can go (starting from your parents and back).

Ireland is one of the EU nations that permits citizenship by descent up to the third generation. You can apply for Irish citizenship if you fit one of the following requirements:
It’s necessary that your parents were included on the Foreign Births Register.
You must first register your birth with the Foreign Births Register in order to submit a legitimate application for citizenship by descent in Ireland. After that, you can continue with the remainder of the application procedure.
ItalyItaly’s citizenship-by-descent rules changed dramatically in 2025. Under Law 74/2025 (effective May 24, 2025), Italian citizenship by descent is now limited to two generations: you must have at least one parent or grandparent who was born in Italy and held Italian citizenship at the time of the “event giving rise to acquisition” (i.e., your birth).
Previously, Italy placed no generational limit on jus sanguinis claims — applicants could trace their lineage back to a great-grandparent, great-great-grandparent, or beyond, as long as the chain of Italian citizenship was never broken. That era is now over.
Grandfather clause: Applications that were submitted to a consulate, Italian municipality, or court — or had an officially confirmed appointment — before 11:59 PM Rome time on March 27, 2025, will still be processed under the old rules.
Constitutional Court confirmation: On March 12, 2026, Italy’s Constitutional Court declared the challenges to Law 74/2025 partly unfounded and partly inadmissible. The reform stands.
1948 rule cases: Claims through the maternal line for ancestors born before January 1, 1948, were already subject to additional restrictions and typically required a court application. Under the new law, these cases are further limited to the two-generation cap.

The following conditions must be met in order to qualify for citizenship by descent under Latvian law:

In Lithuania, you can also obtain citizenship by descent through the third generation. You must have at least one parent, grandparent, or great-grandparent who satisfies the requirements in order to be eligible.

Luxembourg: Recovery Program Now Closed
Luxembourg’s popular citizenship-by-descent recovery program under Article 89 of the 2017 Nationality Act has now fully closed. The program had two steps:
• Step 1 deadline (December 31, 2018): Applicants had to submit a certificate proving their ancestor was a Luxembourg citizen and resided in the country as of January 1, 1900.
• Step 2 deadline (December 31, 2025): Those who completed step 1 had to travel to Luxembourg in person to sign their declaration of citizenship. This deadline was extended twice — first from December 2022 to December 2025 — to accommodate processing backlogs.
Both deadlines have now passed. If you did not complete both steps, this route to Luxembourg citizenship is no longer available.
Other paths: Luxembourg still offers citizenship by naturalization (20 years of residence, or 7 years with language proficiency), and standard descent rules apply if one of your parents is a Luxembourg citizen.

You must have a parent, grandparent, great-grandparent, or an earlier ascendant who was born in Poland and resided there after 1920 in order to be eligible for Polish citizenship via ancestry.
If your ancestor emigrated before 1920, you are still eligible for citizenship as long as you can demonstrate that their address is listed in the Polish, Prussian, Russian, or Austro-Hungarian records and that they were citizens at the time of your birth.
You must keep in mind that if your ancestor acquired a new citizenship prior to 1951, they forfeited their Polish nationality and could not pass it on to you.

Slovakia used to permit citizenship by descent up to the second generation. However, a new modification to the nationality law was passed in 2021, enabling the third generation of descendants of former Slovak and Czechoslovak nationals to petition for citizenship. This means that if your parent, grandparent, or great-grandparent was a citizen of Slovakia, you are eligible to apply for citizenship by descent in Slovakia.
Lithuania is the only EU nation on this list that only allows dual citizenship for people who have ancestors who were Lithuanian before 1940. On the other hand, Germany and Austria permit people who are descended from Nazi victims who had their citizenship revoked during World War II to hold dual nationality.
One of the few EU nations, Slovakia restricts dual citizenship when it is gained by descent. Due to Hungary’s lenient citizenship regulations, which allow any Slovak person with an ancestor in their family line to petition for citizenship in Hungary, Slovakia and Hungary have a contentious relationship as a result of this.

Czechia permits citizenship by descent up to the second generation, so if your parents or grandparents were once Czech citizens, you might be eligible for citizenship there.
Keep in mind that your parents must present proof of paternity at the Registry Office if they were not married and only your father was a citizen of the Czech Republic. A DNA test, a court order, or a joint declaration from both parents could all serve as proof of this.

You may also seek for citizenship if your grandmother or parent is a Maltese citizen. Malta has also made its citizenship regulations more lenient in this area since 2007. For instance, all you have to do to become a citizen is register if you were born outside of Malta but can show that both your parents and your grandparents were born there (in the same direct line).
You cannot obtain Maltese citizenship by descent, however, if your parent passed away after August 1, 2010, without seeking for citizenship. However, if your parent passed away before August 1, 2007, or three years later without submitting a citizenship application on their own, they would still be regarded as a citizen and you might submit a citizenship application on their behalf.

Portugal’s nationality law is undergoing a major overhaul. In April 2026, the Portuguese Parliament approved a revised Nationality Law by a two-thirds majority, with the legislation now sent to the President for review.
Key changes under the new framework:
• Residency for naturalization: The residency requirement for citizenship through naturalization increases from 5 years to 10 years of legal residence. Citizens of CPLP (Community of Portuguese Language Countries) member states and EU nationals would qualify after 7 years.
• Descent claims limited: Eligibility for nationality by descent would be restricted to great-grandchildren of Portuguese nationals, and only where the applicant can demonstrate an “effective and demonstrable connection” to Portugal.
• Genuine connection test: The new law introduces a genuine-link requirement — applicants may need to show knowledge of Portuguese, regular visits, or other ties to the country.
Note: The revised law is still completing the legislative process (presidential review). Check the current status before beginning an application.
For a detailed breakdown, see our full guide: Portuguese Citizenship by Descent: The Complete Guide.

If you had a parent or grandfather who was a Romanian citizen, you might petition for Romanian citizenship via descent. However, if you have a parent, grandparent, or great-grandparent who was born before 1940 in any place in the Kingdom of Romani between 1918 and 1940, including the province of Bessarabia and Northern Bukovina, you may petition for citizenship up to the third generation.

You must have at least one parent or grandparent who was or is a Slovenian citizen to qualify for citizenship by descent from Slovenia. If one of your parents has Slovenian nationality, you can apply to register as a citizen in Slovenia before you are 36 if you were born outside of Slovenia.

Spain’s citizenship-by-descent options are more limited than many other EU countries. Standard Spanish nationality law restricts descent claims to those with a Spanish parent (first generation only).
Ley de Nietos (Grandchildren Law) — now closed: Spain’s Democratic Memory Law (2022) opened a temporary window for grandchildren and great-grandchildren of Spanish exiles and emigrants to apply for citizenship. This was a time-limited program, and the application window has now closed. If you did not submit your application before the deadline, this route is no longer available.
Remaining paths:
• Parent-based descent: If one of your parents is a Spanish citizen, you can claim nationality regardless of where you were born.
• Sephardic Jewish ancestry: Spain previously offered a path for descendants of Sephardic Jews expelled in 1492, though this program has also been subject to changing requirements and deadlines.
• Latin American connection: Citizens of Latin American countries, the Philippines, Equatorial Guinea, and Portugal can apply for Spanish nationality after just 2 years of legal residence, rather than the standard 10.

Only the first generation receives citizenship through descent in Austria. Therefore, children automatically inherit citizenship from their parents if:
According to Austrian law, children have a right to dual citizenship and are not required to choose between the two nationalities when one parent holds a foreign citizenship based on jus sanguinis, such as Austria.

In Belgium, you can only get citizenship via descent through your parents. However, depending on your date of birth, two regulations apply because Belgium changed its citizenship laws in 1984.
If any of the following apply and you were born before to January 1, 1967, you may petition for citizenship:
If any of the following apply to you and you were born after January 1, 1985, you can apply for Belgian citizenship:

Only your parents can apply for citizenship in Denmark. Therefore, regardless of where they were born, children born on July 1, 2014, are regarded as Danish citizens if one of their parents is a citizen of the country. There are, however, different rules for people who were born before this time depending on which parent was a citizen of Denmark and whether they were born in Denmark or not.

Only the first generation can seek for Cyprus citizenship through descent. You must be older than 18 and fulfill the following conditions in order to qualify for citizenship in Cyprus by birth:
You must keep in mind that some restrictions apply if your parents are granted British citizenship.

Only the first generation is eligible for citizenship by descent in Estonia. Therefore, regardless of where you were born, if one of your parents was an Estonian citizen at the time of your birth, you are immediately an Estonian citizen. You must reapply for citizenship if your parents cancelled it before you became 18 though. The Police and Border Guard Board oversees citizenship inquiries and applications.

Citizenship by ancestry from Finland is exclusively carried down through your parents, not from any previous generation. By way of your parents, you can become a citizen of Finland if:
In the following situations, you can still obtain citizenship even though your father passed away before you were born:
In rare cases, you can be qualified for a residence visa in Finland for up to the second generation. You can immigrate to Finland and be regarded as a returnee if one of your parents or grandparents is or was a citizen of Finland. You can then apply for a returnee’s residency visa.

Only if at least one parent had French citizenship at the time of the child’s birth is citizenship by descent permitted in France. However, if neither you nor your parents had any connections to France over the previous 50 years that you lived abroad, you cannot demonstrate citizenship by descent under French law. You (or your parents), for instance, failed to renew your passports, register to vote, register at a French consulate overseas, etc.

Germany is the only country where you can only apply for citizenship by descent through the first generation. However, for Nazi victims and their descendants, nationality through family members in Germany can be extended up to the third generation. A wider range of applicants who can demonstrate that their parent, grandparent, or great-grandparent lost their citizenship under the Nazi dictatorship are now eligible for citizenship in Germany under the country’s new citizenship regulations.

Jus soli is infrequently given in the Netherlands, which has a rigorous nationality law based only on jus sanguinis. Therefore, even if you were born in the Netherlands, if your parents are foreign nationals, you are not a Dutch citizen.
In terms of citizenship by descent, you can only become a citizen if one of your parents is Dutch.
Prior to January 1, 1985, citizenship by descent could only be passed down through the father; however, as of that day, citizenship can also be transmitted down through the mother.
The Netherlands does, however, offer citizenship by option procedure, which is a quicker and simpler approach to become a citizen, but there are a number of requirements you must complete (takes 5 years on average).

Compared to other EU nations, Sweden is one of those that has stricter laws on citizenship by ancestry. Only the first generation of your family can petition for Swedish citizenship by ancestry, and only if one of the following conditions applies to you:

If your parents gave you Icelandic citizenship, then:
You are not eligible for citizenship if you were born between 1964 and 1982 to an Icelandic mother and a non-Icelandic father. The nationality law of Iceland was recently revised, nevertheless, and as a result, you can now apply for citizenship by declaration if:

In all of Europe, Liechtenstein has by far the tightest citizenship regulations. You must have lived in Liechtenstein for at least 30 years in order to become a citizen by naturalization. Therefore, regardless of the place of birth, citizenship by descent is only granted to children born to Liechtenstein citizens.

Another nation that strictly enforces jus sanguinis citizenship regulations is Norway, therefore chances are good that you won’t be granted Norwegian citizenship if you were born there to foreign parents.
However, the way that citizenship regulations apply to you depends on the year that you were born:
* You cannot become a Norwegian citizen in this situation if your parents were not married, but if you are under 18, you can do so by submitting a notification of Norwegian citizenship.

Only the following situations qualify for citizenship by descent in Switzerland:
* Important: If you were born outside of Switzerland to at least one Swiss citizen, you must declare your citizenship to a Swiss authority by the time you are 25 in order to maintain your right to nationality in Switzerland.
Your children will be qualified for Swiss citizenship if you become a citizen in this scenario.

Almost all countries offer citizenship by descent though one or both parents. This is why the emphasis on obtaining citizenship through ancestry usually is placed on countries that offer citizenship for more than 1 generation in the past. Therefore, on our platform we only include citizenship by descent options for countries that offer this possibility for more than 1 generation in the past (even if for some countries this is tied to very specific circumstances, like we saw above).
Keep in mind that some countries do not allow dual citizenship, so you would have to renounce your current citizenship.

For Ukrainian citizenship by descent you have to have at least one grandparent or one parent with Ukrainian citizenship.
Keep in mind that Ukraine does not allow dual citizenship, so you would have to renounce your current citizenship.

Children of parents with Armenian citizenship are also granted citizenship. Those born overseas to a parent or grandparent from Armenian are eligible for Armenian citizenship.
Furthermore, speaking Armenian is not a requirement for obtaining citizenship by descent. The Armenian constitution doesn’t need you to pass an exam, and you aren’t even required to live there.
