Baltic German in the context of "Nicholas Roerich"

Latgale (Latgalian: Latgola; Latvian: Latgale; Russian: Латгалия, romanized: Latgaliya; Polish: Łatgalia; German: Lettgallen; Belarusian: Латгалія, romanized: Lathalija; Belarusian Latin: Łathalija; Latin: Lettgallia), also known as Latgalia or Latgallia, is one of the Historical Latvian Lands. It is the easternmost region of the country and lies north of the Daugava River. While most of Latvia is historically Lutheran, Latgale is predominantly Catholic: 65.3% according to a 2011 survey. After the Counter-Reformation it was the northernmost predominantly Catholic province or region in Europe. There is a considerable Eastern Orthodox minority (23.8%), of which 13.8% are Russian Orthodox Christians and 10.0% are Old Believers. As of 2020, the region's population was 255,968.

The region has a large population of ethnic Russians, especially in Daugavpils, the largest city in the region and the location of the region's only public university, the University of Daugavpils. Many of the Russians who lived in Latgale before Soviet rule are Old Believers. Rēzekne, often called the heart of Latgale, Krāslava, and Ludza are other large towns in the region, which also has a Belarusian minority. There is also a significant Polish minority. As part of the Polotsk and Vitebsk guberniyas, the region was part of the Pale of Settlement and had a very large Jewish population – but many of the Jews were killed in WW2 and most of the remainder emigrated. Other than in Daugavpils, the Baltic German presence in Latgale was less sizable than in other regions of Latvia. According to the Latvian Official Statistics portal, Latgale is the only region of Latvia where the number of Slavs surpasses the number of ethnic Latvians.

Estonia under Swedish rule signifies the period of time between 1561 and 1710, when present-day Estonia was under the rule of the Swedish Empire. In the wake of the breakup of the State of the Teutonic Order, the Baltic German local nobility in the areas of Harrien (Harjumaa) and Wierland (Virumaa), as well as the city of Reval (Tallinn) in June 1561 (and somewhat later Jerwen (Järvamaa)) asked for and were granted protection by the Swedish king Eric XIV, leading to Swedish involvement in the Livonian War. At the conclusion of hostilities in 1583, Sweden was in control of the northern parts of modern Estonia and Dagö (Hiiumaa island); the Duchy of Estonia was created from this territory. Following renewed wars between Poland and Sweden, the southern parts of present-day Estonia (then Livonia) were incorporated into Sweden by the Treaty of Altmark in 1629. Sweden also conquered the island of Ösel (Saaremaa) from Denmark, and were thus in control of all of present-day Estonia.

The time of Swedish rule came to an effective end in 1710, when all the Swedish Baltic provinces capitulated to Russian troops during the end-stages of the Great Northern War. Russian hegemony was formalized in 1721.

Faddey Faddeyevich Bellingshausen or Fabian Gottlieb Benjamin von Bellingshausen (20 September [O.S. 9 September] 1778 – 25 January [O.S. 13 January] 1852) was a Russian cartographer, explorer, and naval officer of Baltic German descent, who attained the rank of admiral. He participated in the first Russian circumnavigation of the globe, and subsequently became a leader of another circumnavigation expedition that discovered the continent of Antarctica. Like Otto von Kotzebue and Adam Johann von Krusenstern, Bellingshausen belonged to a cohort of prominent Baltic German navigators which helped Russia launch its naval expeditions.

Bellingshausen was born on the island of Saaremaa (Ösel), to the Bellingshausen family [de]. He started his service in the Russian Baltic Fleet, and after distinguishing himself joined the first Russian circumnavigation of the Earth in 1803–1806, serving on the merchant ship Nadezhda under the captaincy of Adam Johann von Krusenstern. After the journey, he published a collection of maps of the newly explored areas and islands of the Pacific Ocean. Subsequently, he commanded several ships of the Baltic and Black Sea Fleets.

Karl Khristoforovich Friedrich Knorre; Russian: Карл Христофорович Кнорре (28 March 1801 – 29 August 1883) was a Russian astronomer of Baltic German ethnic origin who is best known for founding the Nikolayev Astronomical Observatory in 1827. Knorre's father, Ernst Friedrich Knorre, and his son, Viktor Knorre, were also prominent astronomers. Recently NASA named an asteroid in honor of the three generations of Knorre astronomers.

Johann Jacob Friedrich Wilhelm Parrot (14 October 1791 – 15 January [O.S. 3 January] 1841) was a Baltic German naturalist, explorer, and mountaineer, who lived and worked in Tartu, Estonia in what was then the Governorate of Livonia of the Russian Empire. A pioneer of Russian and Estonian scientific mountaineering, Parrot is best known for leading the first expedition to the summit of Mount Ararat in recorded history.

Jakob Michael Reinhold Lenz (/lɛnts/; German: [lɛnts]; 23 January 1751 (OS 12 January 1750) – 4 June 1792 [O.S. 24 May 1792]) was a Baltic German writer of the Sturm und Drang movement.

Friedrich Georg Wilhelm von Struve (Russian: Василий Яковлевич Струве, romanized: Vasily Yakovlevich Struve; 15 April 1793 – 23 November [O.S. 11 November] 1864) was a Baltic German astronomer and geodesist. He is best known for studying double stars and initiating a triangulation survey later named Struve Geodetic Arc in his honor.

The Lithuanian nobility (Lithuanian: bajorija) or szlachta of the Grand Duchy of Lithuania (Lithuanian: Lietuvos Didžiosios Kunigaikštystės šlėkta, Polish: szlachta Wielkiego Księstwa Litewskiego) was historically a legally privileged hereditary elite class in the Grand Duchy of Lithuania and Polish Lithuanian Commonwealth (including during period of foreign rule 1795–1918) consisting of Lithuanians from Lithuania Proper; Samogitians from Duchy of Samogitia; following Lithuania's eastward expansion into what is now Belarus, Ukraine and Russia, many ethnically Ruthenian noble families (boyars); and, later on, predominantly Baltic German families from the Duchy of Livonia and Inflanty Voivodeship.

Initially, the privileged social group of the Grand Duchy of Lithuania was called boyars. Boyars became part of the szlachta (nobility) during the Union of Horodło on October 2, 1413, initiating nobility in the Grand Duchy of Lithuania following the Western European model (with a hereditary system of heraldic identification), as well as an increase in the position of the Greater Lithuanian nobility. The Grand Duchy of Lithuania adopted Polish institutions of castellans and voivodes, and 47 selected boyars of Grand Duchy of Lithuania of the Catholic faith were adopted by Polish noble families and received Polish coats of arms.

The Baltic German nobility was a privileged social class in the territories of modern-day Estonia and Latvia. It existed continuously from the Northern Crusades and the medieval foundation of Terra Mariana.

Most of the nobility consisted of Baltic Germans, but with the changing political landscape over the centuries, Polish, Swedish, Russian, Danish, and even Scottish families also became part of the nobility, just as Baltic German families re-settled in locations such as the Swedish and Russian Empires. The nobility of Lithuania is for historical, social and ethnic reasons separated from the German-dominated nobility of Estonia and Latvia.
