Question: How many years did the Franco-Prussian War last? Passage 1:Von Maillinger was born in Passau. After passing his company officer career, at last in the Generalquartiermeister staff in Munich, he was transferred to the General Command in Munich as major of the general staff. The first time, he served for the war ministry, he was ordered by Von Luder. In 1863 he became head of department at the war ministry. Also he was adjutant of Eduard von Lutz, as well as representative of him at the Landtag. In 1865 he was advanced to Oberstleutnant, in 1866 he Oberst. Thenceforward he was commander of the 7th Royal Bavarian Infantry Regiment and deputy of Von Lutz. In 1869 he became major general and commander of the 8th Royal Bavarian Infantry Brigade. One year after that, he was advanced to lieutenant general, and led the 2nd Royal Bavarian Division during the campaigns of the Franco-Prussian War, which stood in France as part of the Bavarian occupation army until 1873. After he returned to Bavaria, he became commander of the II Royal Bavarian Corps. During the period, when he served as war minister, he was advandced to General der Infanterie in 1877 and got the main ownership of the 9th Royal Bavarian Infantry Regiment "Wrede" The psychiatrist and neurologist Prof. Dr. Dr. Dres. h.c. Heinz Hafner says, Maillinger's withdrawal from his ministry post was caused by Ludwig II's reputed sexual abuse of young cavalrists (chevau-legers). Ritter von Maillinger became a member of the Reichsrat in 1888. He died in Bad Aibling. The Maillingerstrae in Munich is named in honor of him.
Passage 2:Maryam Bayramalibeyova was the daughter of Azerbaijani historian and journalist Teymur Bayramalibeyov and his wife Shirin (nee Talyshinskaya), a Russian-educated Talysh-Azerbaijani who translated a number works by classical Russian writers into Azeri and was famous for promoting Western culture in Lankaran and the neighbouring regions. In 1906 Maryam Bayramalibeyova was accepted to the Empress Alexandra Russian Muslim Boarding School for Girls in Baku and 7 years later, to Saint Nina's Secondary Boarding School. In 1917, she graduated from Saint Nina's with honours and was admitted to study medicine at Moscow State University. However, after the October Revolution, being a daughter of an upper-middle class literatus Bayramalibeyova considered her life to be in danger and returned to Lankaran (eventually she did manage to get a post-secondary education receiving an Honours B.A. in law from Baku State University later in 1931). In her native city in 1917, she established the first all-girls secular school (named Uns) in the entire uyezd (administrative unit in Czarist Russia) with the help of Teymur Bayramalibeyov, and became its first principal. The Bayramalibeyovs visited many families in Lankaran encouraging them to send their daughters to Uns. The courses were taught in the Russian language. In order to promote the arts, Maryam Bayramalibeyova organized drama, choir, and musical clubs in the school, which apparently was a success as two of her students later became prominent Azerbaijani actresses and one became a renowned mugham singer. In 1919, Bayramalibeyova founded the Lankaran Women's Charity Association.
