Question: Passage: Another civil war ensued after the death of Karim Khan in 1779, out of which Aqa Mohammad Khan emerged, founding the Qajar Dynasty in 1794. In 1795, following the disobedience of the Georgian subjects and their alliance with the Russians, the Qajars captured Tblisi by the Battle of Krtsanisi, and drove the Russians out of the entire Caucasus, reestablishing a short-lived Iranian suzerainty over the region. The Russo-Persian wars of 1804–1813 and 1826–1828 resulted in large irrevocable territorial losses for Iran in the Caucasus, comprising all of Transcaucasia and Dagestan, which made part of the very concept of Iran for centuries, and thus substantial gains for the neighboring Russian Empire. Question: Whose death in 1779 led to a civil war in Iran?

Answer: Karim Khan


Question: Passage: The breakup of the Carolingian Empire was accompanied by invasions, migrations, and raids by external foes. The Atlantic and northern shores were harassed by the Vikings, who also raided the British Isles and settled there as well as in Iceland. In 911, the Viking chieftain Rollo (d. c. 931) received permission from the Frankish King Charles the Simple (r. 898–922) to settle in what became Normandy.[Q] The eastern parts of the Frankish kingdoms, especially Germany and Italy, were under continual Magyar assault until the invader's defeat at the Battle of Lechfeld in 955. The breakup of the Abbasid dynasty meant that the Islamic world fragmented into smaller political states, some of which began expanding into Italy and Sicily, as well as over the Pyrenees into the southern parts of the Frankish kingdoms. Question: Who was king of the Franks in 899?

Answer: Charles the Simple
