Question: Who is in charge of the city Couceiro arrived in in 1889? Passage:Paiva Couceiro arrived in Luanda, Angola on September 1, 1889, and was immediately appointed commander of the Irregular Cavalry Squadron in the village of Humpata (which was originally created by Artur de Paiva to combat bands of guerrillas along the plain of Moçâmedes). He did not remain at this outpost for long; apparently he was unsatisfied with his subordinates, their methods and inferior level of discipline, but was able to utilize them in a campaign to retrieve missing cattle, instead of hiring local Boer mercenaries, which had been the custom. By January he was in the village of Belmonte, in Bié, on a mission that would take him along the Cuando River, to Cuito and then to the Lialui along the Zambezi River (a trek of thousands of kilometers across savannah), in order to negotiate with Lewanika, chief of the Barotze tribe. The growth of the Portuguese occupation force in the Angolan interior was part of the administration's attempted to implement their Pink Map to explore and expand their serfdom over the peoples of the central-African interior. After some resistance, the colonial administration began a military campaign to pacify groups that had resisted initial token gestures of friendship and gifts, a process that Paiva Couceiro participated in energetically. For the chief's recognition of Portuguese sovereignty over his territories, Paiva Couceiro brought with him a colonels tunic and sword, textiles, gold, velvet, boxes of Porto wine and arms, which were to be delivered in 300 crates when the Governor of Angola canceled the project.

Question: Did Ida's father have more than one child? Passage:The Anglo-Saxon Chronicle indicates that Ida's reign began in 547, and records him as the son of Eoppa, grandson of Esa, and great-grandson of Ingwy. Likewise, the Historia Brittonum calls him as the son of Eoppa and the first king of Berneich or Bernicia. The Anglo-Saxon Chronicle elaborates that he ruled for twelve years and built the Bernician capital of Bamburgh Castle. Later, however, the Chronicle confuses his territory with the later Northumbria, saying that Ælla, historically a king of Deira rather than Bernicia, succeeded him as king after his death. Northumbria did not exist until the union of Bernicia with the kingdom of Deira; this happened for the first time under Ida's grandson Æthelfrith. The genealogies of the Anglo-Saxon kings attached to some manuscripts of the Historia Brittonum give more information on Ida and his family; the text names Ida's "one queen" as Bearnoch and indicates that he had twelve sons, naming among them Adda, Æthelric, Theodric, Eadric, Theodhere, Osmere and Ealric. Several of these are listed as kings. One of them, Theodric, is noted for fighting against a Brittonic coalition led by Urien Rheged and his sons. The genealogical preface to Chronicon ex chronicis names six sons, Adda, Bealric, Theodric, Ethelric, Osmere, and Theodhere, born to his wife and six born to concubines, Ocga, Alric, Ecca, Oswald, Sogor and Sogothere. Ida's successor, Glappa, does not appear among his sons in any of the early sources. Ida's descendants would rule Bernicia and later Northumbria.

Question: Despite Gilberts and Sullivan's partnership collapsing after the production in 1889, how many performances were there before it closed at the Savoy Theatre? Passage:When the Gilbert and Sullivan partnership collapsed after the production of The Gondoliers in 1889, their producer Richard D'Oyly Carte struggled to find successful new works to show at the Savoy Theatre. Carte produced Sullivan's grand opera, Ivanhoe at another theatre, and afterwards, he turned to Sullivan to create more comic operas for the Savoy. With Sydney Grundy, Sullivan wrote the nostalgic and sentimental Haddon Hall (1892) then, reunited with W. S. Gilbert, he produced Utopia, Limited (1893). He next returned, with his earlier collaborator F. C. Burnand, with The Chieftain (1894) and collaborated for the last time with Gilbert on The Grand Duke (1896). None of these had proved to be more than modestly successful, and Carte's other new pieces for the Savoy in the 1890s had done no better. Following the success of Sullivan's ballet Victoria and Merrie England in 1897, Carte asked Sullivan to work on another new opera for the Savoy.
