Ancient and Classical Periods

Stone Age tools dating back 20,000 years have been excavated in the state, showing human occupation 8,000 years earlier than scholars had thought.[26] According to the Indian epic Mahabharata the region was part of the Vanga Kingdom.[27] Several Vedic realms were present in the Bengal region, including Vanga, Rarh, Pundravardhana and the Suhma Kingdom. One of the earliest foreign references to Bengal is a mention by the Ancient Greeks around 100 BCE of a land named Gangaridai located at the mouths of the Ganges.[28] Bengal had overseas trade relations with Suvarnabhumi (Burma, Lower Thailand, the Lower Malay Peninsula and Sumatra).[29] According to the Sri Lankan chronicle Mahavamsa, Prince Vijaya (c. 543 – c. 505 BCE), a Vanga Kingdom prince, conquered Lanka (modern-day Sri Lanka) and named the country Sinhala Kingdom.[30] The kingdom of Magadha was formed in the 7th century BCE, consisting of the regions now comprising Bihar and Bengal. It was one of the four main kingdoms of India at the time of the lives of Mahavira, the principal figure of Jainism and Gautama Buddha, founder of Buddhism. It consisted of several janapadas, or kingdoms.[31] Under Ashoka, the Maurya Empire of Magadha in the 3rd century BCE extended over nearly all of South Asia, including Afghanistan and parts of Balochistan. From the 3rd to the 6th centuries CE, the kingdom of Magadha served as the seat of the Gupta Empire.[32] A map showing the extent of the Pala Empire The Pala Empire was an imperial power during the Late Classical period on the Indian subcontinent, which originated in the region of Bengal Two kingdoms—Vanga or Samatata, and Gauda—are said in some texts to have appeared after the end of the Gupta Empire although details of their ascendancy are uncertain.[33] The first recorded independent king of Bengal was Shashanka, who reigned in the early 7th century.[34] Shashanka is often recorded in Buddhist annals as an intolerant Hindu ruler noted for his persecution of the Buddhists. He murdered Rajyavardhana, the Buddhist king of Thanesar, and is noted for destroying the Bodhi tree at Bodhgaya, and replacing Buddha statues with Shiva lingams.[35] After a period of anarchy,[36]:36 the Pala dynasty ruled the region for four hundred years beginning in the 8th century. A shorter reign of the Hindu Sena dynasty followed.[37] Rajendra Chola I of the Chola dynasty invaded some areas of Bengal between 1021 and 1023.[38] Islam was introduced through trade with the Abbasid Caliphate.[39] Following the early conquest of Muhammad bin Bakhtiyar Khalji and the establishment of the Delhi Sultanate, it spread across the entire Bengal region. Later, occasional Muslim raiders reinforced the process of conversion by building mosques, madrasas and khanqahs. During the Islamic Bengal Sultanate, founded in 1352, Bengal was major world trading nation and was often referred by the Europeans as the richest country with which to trade.[40] Later, in 1576, it was absorbed into the Mughal Empire.[4 https://en.wikipedia.org/wiki/West_Bengal
