(Zheleznodorozhny), Insterburg/Įsrutis (Chernyakhovsk), Memel/Klaipėda (three churches, one of Lithuanian language), Puschdorf-Stablack/Stablaukis (Stabławki), Ragnit/Ragainė (Neman), Saalau/Želva (Kamenskoye), Tapiau/Tepliava (Gvardeysk), Tilsit/Tilžė (Sovetsk), and Wehlau/Vėluva (Znamensk). By 1531, more parishes had been founded; several of them were supervised by an archpriest (later called superintendent) on behalf of the bishop or the Pomesanian Consistory (est. in 1602 in Saalfeld in Prussia/Zaalfeld (Zalewo)), after giving up the episcopate in 1587). Between 1529 and 1600, 31 Lutheran churches, mostly simple structures, were erected in Lithuania Minor. By the end of the 17th century, the number of Lutheran parishes in Lithuania Minor reached 112, with 68 offering Lithuanian services before the great plague (1709–1711), which killed about half the population and reduced the parishes with Lithuanian services to 59. In most parishes with services in Lithuanian and German, the same pastor served both language groups. Only in the cities of Königsberg (Church of St. Nicholas, Steindamm; Lithuanian Church of St. Elisabeth, and Sackheim), Memel, and Tilsit were separate churches exclusively used for parishes of Lithuanian language. Between 1700 and 1918, another 51, usually more massive, churches were erected. In order to restaff orphaned pastorates after the plague, King Frederick William I of Prussia established two departments: in 1718, the Lithuanian Seminary (, closed in 1944) at Albertina, and in 1727, another one (Halės lietuvių kalbos seminaras) at the University of Halle upon Saale, closed in 1740. Johann Jakob Quandt, who also published a Lithuanian bible, a milestone in Lithuanian language standardization that was translated by him and a team of nine other theologians, was the first head of the seminary at Albertina. The king established a fund granting scholarships for eight students at Albertina and free food for twelve students in Halle. Kristijonas Donelaitis, alumnus of Albertina Lithuanian Seminary and Lutheran pastor, became a famous poet who wrote a masterpiece of early Lithuanian literature. Daniel Klein, another Albertina alumni and pastor of Tilsit, wrote the first grammar book of the Lithuanian language and hymns, 36 of which are still in use in the Lithuanian Lutheran church today. Consistorial Councillor Ludwig Rhesa/Liudvikas Rėza, an Albertina alumni and professor leading the Lithuanian Seminary since 1810, distinguished himself as a collector and publisher of Lithuanian poems and re-editions of the Lithuanian bible in 1824. The archpriests of Lithuania Minor were based in Tilsit (as of 1547), Ragnit (as of 1554), Insterburg (as of 1575), Schaaken in Prussia/Šakiai (Niekrasovo) (as of
