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]
Roman Senate During the days of the kingdom, it was little more than an advisory council to the king. The last king of Rome, Lucius Tarquinius Superbus, was overthrown following a coup d'état led by Lucius Junius Brutus, who founded the Republic of Rome.
