Problem: I know that the answer to the question "What is the equivalent name of empire?" is in "The Chalukya Empire (Kannada: [taukj]) was an Indian royal dynasty that ruled large parts of southern and central India between the 6th and the 12th centuries. During this period, they ruled as three related yet individual dynasties. The earliest dynasty, known as the "Badami Chalukyas", ruled from Vatapi (modern Badami) from the middle of the 6th century. The Badami Chalukyas began to assert their independence at the decline of the Kadamba kingdom of Banavasi and rapidly rose to prominence during the reign of Pulakeshin II. The rule of the Chalukyas marks an important milestone in the history of South India and a golden age in the history of Karnataka. The political atmosphere in South India shifted from smaller kingdoms to large empires with the ascendancy of Badami Chalukyas. A Southern India-based kingdom took control and consolidated the entire region between the Kaveri and the Narmada rivers. The rise of this empire saw the birth of efficient administration, overseas trade and commerce and the development of new style of architecture called "Chalukyan architecture". The Chalukya dynasty ruled parts of southern and central India from Badami in Karnataka between 550 and 750, and then again from Kalyani between 970 and 1190.". Can you tell me what it is?

Problem: I know that the answer to the question "When the Dutch decided to halt the exertion of too much English control in India what were they in contemplation of?" is in "Many middle and small powers in Europe, unlike in the previous wars, tried to steer clear away from the escalating conflict, even though they had interests in the conflict or with the belligerents, like Denmark-Norway. The Dutch Republic, long-time British ally, kept its neutrality intact, fearing the odds against Britain and Prussia fighting the great powers of Europe, even tried to prevent Britain's domination in India. Naples, Sicily, and Savoy, although sided with Franco-Spanish party, declined to join the coalition under the fear of British power. The taxation needed for war caused the Russian people considerable hardship, being added to the taxation of salt and alcohol begun by Empress Elizabeth in 1759 to complete her addition to the Winter Palace. Like Sweden, Russia concluded a separate peace with Prussia.". Can you tell me what it is?
