Question

how did rome motivate conquered peoples to pay taxes, supply soldiers, and stay loyal to the government

Answer 1

Well Rome had already conquered many places, so by fear and propaganda. Anyone who said "no" to the Roman government was either locked up or killed/tortured. The Roman leader was a dictator and a tyrant, who soon took away the liberty and freedoms of all the people.
