Where to Start Genealogical Research in Belarus and Lithuania
Published on March 16, 2026
If you are starting genealogical research in the territories of modern-day Belarus and Lithuania, there are several important points that should be clarified before beginning your work.
The history of this region is complex, and political borders, administrative systems, and religious structures changed many times over the past two centuries. Understanding a few key factors in advance can significantly simplify the search for historical records.
The history of this region is complex, and political borders, administrative systems, and religious structures changed many times over the past two centuries. Understanding a few key factors in advance can significantly simplify the search for historical records.
1. Religion
Religion is often the first and most important question in genealogical research of this region. Historically, many different ethnic groups lived on the territories of present-day Belarus and Lithuania, and they were generally allowed to practice the religion of their ancestors. In the 18th and 19th centuries, several confessions were widespread here, including Catholicism, Orthodoxy, Uniatism, Judaism, Old belief and Protestantism (particularly Lutheranism).
The denomination of the parish determines where records of births, marriages, and deaths should be searched. Once you are able to identify the correct parish — the specific church or religious community — it becomes much easier to determine which archive holds the parish registers containing these records.
2. Time Period
Historical context also plays a crucial role. After the territories of Belarus and Lithuania were incorporated into the Russian Empire at the end of the 18th century, certain religious communities gradually began to face restrictions. These changes often affected the way records were created and preserved.
For example, after the uprising of 1831, Uniate churches were rapidly abolished, and their parishioners were forcibly transferred to the Orthodox Church. Later, following the uprising of 1863, a similar wave of pressure was directed against Catholic institutions. Because of these changes, records for the same family may sometimes appear in different church registers depending on the time period.
3. The Interwar Period
For more recent generations, especially those who lived between the two World Wars, knowledge of regional political history becomes particularly important.
In the 1920s, Belarus was divided into two parts. Western Belarus became part of Poland (the Second Polish Republic), while Eastern Belarus was governed by Soviet authorities. A real state border existed between these territories, complete with guards and penalties for violating the border regime. Lithuania, meanwhile, gained independence and remained a sovereign state until 1940. As a result, records from the same family may now be preserved in different countries depending on where they lived during this period.
All of these factors directly influence where genealogical documents are stored today. Records relating to families from this region may now be found in the archives of Belarus, Lithuania, or Poland. Experienced genealogists take these historical and administrative changes into account when conducting research. Understanding these complexities can help navigate archival systems more effectively and uncover the stories of earlier generations.
