Question: How long did the Austro-Prussian War last? Passage 1:She was born in the Kaʻū district of the Island of Hawaiʻi, to Mary Paʻahana Kanakaʻole (a native Hawaiian woman) and Henry Nathaniel Wiggin (originally from Massachusetts). In the traditional custom of hānai, she was initially reared by her mother's parents. Her grandmother Naliipoʻaimoku, a traditional dancer in the court of Queen Emma, taught her chants and stories, while her grandfather Keli'ikanaka'ole-o-Haililani (k) was a healer and kahuna pale keiki (obstetrician) who used lomilomi massage, laʻau lapaʻau (herbal medicine), hoʻoponopono (forgiveness), and pule (prayer). Her great grandmother Keliʻipaʻahana was a kahuna pule (priestess) in the Pele line. Keli'iPa'ahana's parents were the High Chief KU or Kauhi and High Chiefess Na'ai Hunali'i (The Hidden chief). Keli'iPa'ahana was interned in Halema'uma'u in 1869 in the Ka'u district. She married the High Chief Keli'iKanaka'ole (k) the son High Chief Kaelele and Princess Kekelaokalani. Family is known to inherit the sacred Ali'i Moe Kapu (the prostrating Taboo). Upon the death of her grandmother Nali'i Poai moku she returned to live with her parents and spoke both Hawaiian and English.
 Passage 2:The last meetings had revealed the rising antagonism with Britain and France, especially on Italian unification, the right to self-determination and the Eastern Question. The Alliance is conventionally taken to have become defunct with Alexander's death in 1825. France ultimately went her separate way after the July Revolution of 1830, leaving the core of Russia, Austria and Prussia as Central-Eastern European block which once again congregated to suppress the Revolutions of 1848. The Austro-Russian alliance finally broke up in the Crimean War: though Russia had helped to completely destroy the Hungarian Revolution of 1848, Austria did not take any action to support her ally, declared herself neutral and even occupied the Wallachian and Moldavian lands on the Danube upon the Russian retreat in 1854. Thereafter, Austria remained isolated, which added to the loss of her leading role in the German lands, culminating in the defeat of the Austro-Prussian War in 1866.
 Passage 3:Herschel was born in Slough, Buckinghamshire, the son of Mary Baldwin and William Herschel. He was the nephew of astronomer Caroline Herschel. He studied shortly at Eton College and St John's College, Cambridge, graduating as Senior Wrangler in 1813. It was during his time as an undergraduate that he became friends with the mathematicians Charles Babbage and George Peacock. He left Cambridge in 1816 and started working with his father. He took up astronomy in 1816, building a reflecting telescope with a mirror in diameter, and with a focal length. Between 1821 and 1823 he re-examined, with James South, the double stars catalogued by his father. He was one of the founders of the Royal Astronomical Society in 1820. For his work with his father, he was presented with the Gold Medal of the Royal Astronomical Society in 1826 (which he won again in 1836), and with the Lalande Medal of the French Academy of Sciences in 1825, while in 1821 the Royal Society bestowed upon him the Copley Medal for his mathematical contributions to their Transactions. Herschel was made a Knight of the Royal Guelphic Order in 1831.
