full_context: Document 1: Vladimir Vysotsky: Vladimir Semyonovich Vysotsky (Russian: Влади́мир Семёнович Высо́цкий ; ] ; 25 January 1938 – 25 July 1980) was a Russian singer-songwriter, poet, and actor whose career had an immense and enduring effect on Soviet and Russian culture.

Document 2: Neo-Lutheranism: Neo-Lutheranism was a 19th-century revival movement within Lutheranism which began with the Pietist driven "Erweckung," or "Awakening", and developed in reaction against theological rationalism and pietism. This movement followed the Old Lutheran movement and focused on a reassertion of the identity of Lutherans as a distinct group within the broader community of Christians, with a renewed focus on the Lutheran Confessions as a key source of Lutheran doctrine. Associated with these changes was a renewed focus on traditional doctrine and liturgy, which paralleled the growth of Anglo-Catholicism in England. It was sometimes even called "German Puseyism". In the Roman Catholic Church in Germany, neo-Lutheranism was paralleled by Johann Adam Möhler. The chief literary organ of the neo-Lutheranism was "Evangelische Kirchenzeitung", edited by Ernst Wilhelm Hengstenberg.
Document 3: Latvian name: Latvian names, like in most European cultures, consist of two main elements: the given name ("vārds") followed by family name ("uzvārds"). During the Soviet occupation (1940 - 1991) the practice of giving a middle name was discouraged, but since the restoration of Independence Latvian legislation again allows giving of up to two given names and it has become more common to give a middle name to children.
Document 4: Wilhelm Dichter: Wilhelm Dichter is a Polish American writer who has written three novels based on his life. He was born in 1935 in Borysław (in modern-day Ukraine), where he survived the war. His father had died, and he and his mother (remarried after the war) came to live in Poland toward the end of 1944. He finished his studies at the Warsaw Polytechnic, where he earned his doctorate in mechanical engineering and worked for 13 years until 1968. The antisemitic campaign in 1968 in Poland provided the opportunity for him and his family to emigrate, through Vienna and Rome, eventually settling in the United States. As an expert in ballistics, he worked at Colt Firearms in the R&D division on Long Island, New York, and later in Hartford Connecticut. In 1978, he made a transition to the field of image processing, becoming an image processing algorithm design specialist at the Linotype-Hell company. Wilhelm Dichter is now retired from his engineering and scientific work. When he is not writing, Wilhelm and his wife Ola spend quality time with their grandchildren. He and Ola live in the Boston area.
Document 5: Bahá'í Faith in Poland: The Bahá'í Faith in Poland begins in the 1870s when Polish writer wrote several articles covering its early history in Persia. There was a polish language translation of Paris Talks published in 1915. After becoming a Bahá'í in 1925 Poland's Lidia Zamenhof returned to Poland in 1938 as its first well known Bahá'í. During the period of the Warsaw Pact Poland adopted the Soviet policy of oppression of religion, so the Bahá'ís, strictly adhering to their principle of obedience to legal government, abandoned its administration and properties. An analysis of publications before and during this period finds coverage by Soviet-based sources basically hostile to the religion while native Polish coverage was neutral or positive. By 1963 only Warsaw was recognized as having a community. Following the fall of communism in Poland because of the Revolutions of 1989, the Bahá'ís in Poland began to initiate contact with each other and have meetings - the first of these arose in Kraków and Warsaw. In March 1991 the first Bahá'í Local Spiritual Assembly was re-elected in Warsaw. Poland's National Spiritual Assembly was elected in 1992. According to Bahá'i sources there were about three hundred Bahá'ís in Poland in 2006 and there have been several articles in polish publications in 2008 covering the Persecution of Bahá'ís in Iran and Egypt. The Association of Religion Data Archives (relying on World Christian Encyclopedia) estimated the Bahá'ís at about 990 in 2005.
Document 6: Baltic neopaganism: Baltic Neopaganism is a category of autochthonous religious movements which have revitalised within the Baltic people (primarily Lithuanians and Latvians).

He lived and worked in Lithuania Minor, a territory in the Kingdom of Prussia, that had a sizable minority of ethnic Lithuanians.

Document 8: List of Lithuanian mythological figures: The list of Lithuanian gods is reconstructed based on scarce written sources and late folklore. Lithuania converted to Christianity in 1387, but elements of Lithuanian mythology survived into the 19th century. The earliest written sources, authored by foreigners and Christians, only briefly mention the Lithuanian gods. Beginning in the 16th century, the pagan religion received more attention from authors, but often their accounts were confused, contradictory, and heavily influenced by various religious agendas. Collection and recording of folklore began in the 19th century, by which time the pagan mythology had become fragmented and mixed with Christian traditions. The cults of old deities transformed into folklore (individual tales, myths, songs, etc.) without associated rituals. Because of such difficulties obtaining data, there is no accepted list of Lithuanian gods. Different authors present wildly contradictory reconstructions of the Lithuanian pantheon.
Document 9: Vytautas: Vytautas (c. 1350 – October 27, 1430), also known as Vytautas the Great (Lithuanian: "   ", Belarusian: "Вітаўт Кейстутавіч (Vitaŭt Kiejstutavič)" , Polish: "Witold Kiejstutowicz" , Rusyn: "Vitovt", Latin: "Alexander Vitoldus") from the 15th century onwards, was a ruler of the Grand Duchy of Lithuania, which chiefly encompassed the Lithuanians and Ruthenians.

Document 10: Lietuvininkai we are born: Lietuvininkai we are born (German: "Als Litauer sind wir geboren" , Lithuanian: "Lietuvninkai mes esam gimę" ) is a Lithuanian-language patriotic and sentimental poem written by the German linguist Georg Sauerwein in 1879. It is a passionate defense of Prussian Lithuanian (Lietuvininkai) language and culture, rallying people to resist Germanisation attempts. However, at the same time the poem proclaimed love and loyalty to the Kaiser signifying that the rally was cultural and not political. It was inspired by Enlightenment ideas that archaic languages and traditions of minorities should be cherished, studied, and preserved. The poem was first published in the Prussian Lithuanian newspaper "Lietuwißka Ceitunga" in 1879.
Document 11: Edward Stachura: Edward Stachura (18 August 1937 – 24 July 1979) was a Polish poet and writer. He rose to prominence in the 1960s, receiving prizes for both poetry and prose.
