Mehrstaatlichkeit

Mehrstaatlichkeit refers to the condition of being a citizen of more than one state simultaneously. This can arise through various circumstances, such as birth in one country to parents who are citizens of another, or through naturalization in a new country without renouncing one's original citizenship. Many countries permit Mehrstaatlichkeit, while others require individuals to choose a single nationality.

The legal framework governing Mehrstaatlichkeit varies significantly worldwide. Some nations automatically grant citizenship based on jus soli (right of soil), meaning birth within their territory, while others rely on jus sanguinis (right of blood), conferring citizenship through parentage. When an individual holds citizenship in two or more countries, they are subject to the laws and obligations of each state. This can include rights such as residing and working in those countries, as well as responsibilities like military service or taxation.

International agreements and conventions, such as the 1963 Convention on the Reduction of Statelessness and the 1997 European Convention on Nationality, aim to address issues related to Mehrstaatlichkeit and to prevent statelessness. However, the recognition and implications of holding multiple citizenships are ultimately determined by the national laws of the states involved. The trend in many parts of the world is towards greater acceptance of Mehrstaatlichkeit, reflecting increased global mobility and interconnectedness.
