Cittadinanza per discendenza

Could a line from Algua qualify for Italian citizenship?

If your ancestor was born in Algua, Italy may recognize you as a citizen under jure sanguinis (citizenship by descent).

The birthplace alone does not decide it. Each generation between that ancestor and you does: who naturalized, and when. Since the 2025 law, the number of generations matters too.

The checker goes back through your line one generation at a time. It is not legal advice, and it does not search for records.
