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]
Vizier (Ancient Egypt) The viziers were appointed by the pharaohs but often belonged to a pharaoh's family. The vizier's paramount duty was to supervise the running of the country, much like a prime minister. At times this even included small details such as sampling the city's water supply.[4] All other lesser supervisors and officials, such as tax collectors and scribes, would report to the vizier. The judiciary was part of the civil administration and the vizier also sat in the High Court. However, at any time, the pharaoh could exert his own control over any aspect of government, overriding the vizier's decisions. The vizier also supervised the security of the pharaoh and the palace by overseeing the comings and goings of palace visitors[5]. Viziers were the second in command, they oversaw the political administration and all official documents had to have his seal on them, managed the taxation system and monitored the supply of food, listened to problems between nobles and settled them, and ran the pharaoh’s household and ensured the royal family’s safety.[6] From the Fifth Dynasty onwards viziers, whom by then were the highest civilian bureaucratic official, held supreme responsibility for the administration of the palace and government including jurisdiction, scribes, state archives, central granaries, treasury, storage of surplus products and their redistribution, and supervision of building projects such as the royal pyramid. [7]In the New Kingdom, there were two viziers, one for Upper Egypt and one for Lower Egypt.[8]
