in the Nesari plates (805 AD) of the south Indian ruler Rashtrakuta Govinda III, who invaded northern India in the 9th century, which speak of Dharmapala as the king of Vangala. The records of Rajendra Chola I of the Chola dynasty, who invaded Bengal in the 11th century, affirms Govinda Chandra as the ruler of Bengal. Shams-ud-din Ilyas Shah took the title "Shah-e-Bangalah" and united the whole region under one government for the first time. The Vanga Kingdom (also known as Banga) was located in the eastern part of the Indian Subcontinent, comprising part of present-day modern Bangladesh and India's West Bengal. Vanga and Pundra were two dominant tribes in Bangladesh in ancient time. Ancient period Pre-historic Bengal The Oxford History of India categorically claims that there is no definitive information about Bengal before the third century BCE. It is believed that there were movements of Indo-Aryans, Dravidians and Mongoloids, including a people called Vanga, into Bengal. The Bengal delta was made up of thick jungles and wetlands for several millennia. A major part of this geography lasted till historical times. The loss of the jungle was due to human activity. Bengal had an early human presence, but there is no consensus for the time frame of the first human activity in Bengal nor are there plenty of remains. One view contends that humans entered Bengal from China 60,000 years ago. Another view claims that a distinct regional culture emerged 100,000 years ago. There is weak evidence for a prehistoric human presence in the region. There is scant evidence of a human presence during the Neolithic and Chalcolithic eras. This could be because of the shifts in the rivers' courses. The Bengali climate and geography is not suitable for tangible archaeological remains. Due to lack of stones the early humans in Bengal probably used materials such as wood and bamboo that could not survive in the environment. South Asian archaeologists have tended to focus on other parts of the subcontinent. Archaeologists interested in Bengal have focused on more recent history. Archaeological discoveries are almost entirely from the hills around the Bengal delta. West Bengal and Bangladesh's eastern terrain offer the best source of information about the early peoples of Bengal. Industries of fossil-wood manufacturing blades, scrapers and axes have been discovered in Lalmai, Sitakund and Chaklapunji. These have been connected with similar findings in Burma and West Bengal.
