question:
Medieval Cholas rose to prominence during the middle of the 9th century C.E. and established the greatest empire South India had seen. They successfully united the South India under their rule and through their naval strength extended their influence in the Southeast Asian countries such as Srivijaya. Under Rajaraja Chola I and his successors Rajendra Chola I, Rajadhiraja Chola, Virarajendra Chola and Kulothunga Chola I the dynasty became a military, economic and cultural power in South Asia and South-East Asia. Rajendra Chola I's navies went even further, occupying the sea coasts from Burma to Vietnam, the Andaman and Nicobar Islands, the Lakshadweep (Laccadive) islands, Sumatra, and the Malay Peninsula in Southeast Asia and the Pegu islands. The power of the new empire was proclaimed to the eastern world by the expedition to the Ganges which Rajendra Chola I undertook and by the occupation of cities of the maritime empire of Srivijaya in Southeast Asia, as well as by the repeated embassies to China. They dominated the political affairs of Sri Lanka for over two centuries through repeated invasions and occupation. They also had continuing trade contacts with the Arabs in the west and with the Chinese empire in the east. Rajaraja Chola I and his equally distinguished son Rajendra Chola I gave political unity to the whole of Southern India and established the Chola Empire as a respected sea power. Under the Cholas, the South India reached new heights of excellence in art, religion and literature. In all of these spheres, the Chola period marked the culmination of movements that had begun in an earlier age under the Pallavas. Monumental architecture in the form of majestic temples and sculpture in stone and bronze reached a finesse never before achieved in India.
answer:
What area did the Cholas unite in the 9th century?


question:
After the lengthy Iraq disarmament crisis culminated with an American demand that Iraqi President Saddam Hussein leave Iraq, which was refused, a coalition led by the United States and the United Kingdom fought the Iraqi army in the 2003 invasion of Iraq. Approximately 250,000 United States troops, with support from 45,000 British, 2,000 Australian and 200 Polish combat forces, entered Iraq primarily through their staging area in Kuwait. (Turkey had refused to permit its territory to be used for an invasion from the north.) Coalition forces also supported Iraqi Kurdish militia, estimated to number upwards of 50,000. After approximately three weeks of fighting, Hussein and the Ba'ath Party were forcibly removed, followed by 9 years of military presence by the United States and the coalition fighting alongside the newly elected Iraqi government against various insurgent groups.
answer:
What demand did the US make before invading Iraq in 2003?
