What ideas did the US adopt from rome?

Answer 1

Democracy.

Democracy was a Greek concept. Rome did not have a democracy. The ideas borrowed from Rome were the concept of checks and balances of powers and the veto

Answer 2

In its time, ancient Rome had a sophisticated form of government compared to earlier civilizations. Many historians would say that when the ancient Roman Republic was at its best, there existed in parts what can be called a "balance of power"among the various income groups and social groups. The function of balancing power is what early statesman in the United States found attractive.

The "republic" constructed by the writers of the US Constitution, for its time, created a balance of power within the structure of the Federal Government, and further to this balancing power between the central government and the various States of the Union.

It also must be remembered that in the ancient Roman republic, the right to vote meant something, it was an important step in antiquity. Unlike various "kingdoms" of the ancient world, "voting" by citizens was a rarity.

In the time the USA began its existence, many countries were ruled by a king. The idea of "voting" was not an option in most places in the 18th century.

The power of the vote, found in the ancient Roman republic, was part & parcel of the foundation the US's founding fathers wanted to build into their new government.
