who was considered the most powerful chola ruler
Chola dynasty Rajaraja Chola I and Rajendra Chola I were the greatest rulers of the Chola dynasty, extending it beyond the traditional limits of a Tamil kingdom.[38] At its peak, the Chola Empire stretched from the island of Sri Lanka in the south to the Godavari-Krishna river basin in the north, up to the Konkan coast in Bhatkal, the entire Malabar Coast in addition to Lakshadweep, Maldives, and vast areas of Chera country. Rajaraja Chola I was a ruler with inexhaustible energy, and he applied himself to the task of governance with the same zeal that he had shown in waging wars. He integrated his empire into a tight administrative grid under royal control, and at the same time strengthened local self-government. Therefore, he conducted a land survey in 1000 CE to effectively marshall the resources of his empire.[52] He also built the Brihadeeswarar Temple in 1010 CE.[53]
Gupta Empire The Gupta Empire was an ancient Indian empire, existing from approximately 240 to 590 CE. At its zenith from approximately 319 to 550 CE it covered much of the Indian subcontinent.[1] This period is called the Golden Age of India.[2][note 1] The ruling dynasty of the empire was founded by Sri Gupta; the most notable rulers of the dynasty were Chandragupta I, Samudragupta, and Chandragupta II. The 5th-century CE Sanskrit poet Kalidasa credits the Guptas with having conquered about twenty-one kingdoms, both in and outside India, including the kingdoms of Parasikas, the Hunas, the Kambojas, tribes located in the west and east Oxus valleys, the Kinnaras, Kiratas, and others.[4][non-primary source needed]
