Question

what was the reason behind the conflict amongst the 16 mahajanapadas(don't say only names)​

Answer 1

Answer:

The Mahājanapadas (Sanskrit: महाजनपद, lit. 'great realm', from maha, "great", and janapada "foothold of a tribe, country") were sixteen kingdoms or oligarchic republics that existed in ancient India from the sixth to fourth centuries BCE. Two of them were most probably ganatantras (republics) and others had forms of monarchy. Ancient Buddhist texts like the Anguttara Nikaya[1] make frequent reference to sixteen great kingdoms and republics which had evolved and flourished in a belt stretching from Gandharain the northwest to Anga in the eastern part of the Indian subcontinent and included parts of the trans-Vindhyan region,[2] prior to the rise of Buddhism in India.
