The United States has some experiences/conflicts that are seen on a consistent basis.
For example, the power of the federal government is one that has been seen throughout history. The development of the US Constitution saw Anti-federalists fighting against Federalists in terms of what rights/powers the federal government should have. Today, debates still arise over the issue of what powers the federal government has, especially when it comes to the issue of implied powers.
One success that we share with the Americans in the past is the desire for innovation. Throughout American history, developments in communication and transportation continue to positively influence American society. Even though this is different depending on the time period, the spirit of ingenuinity is something that is seen in all times of American history. This is especially true for the era of the Market Revolution (development of canals, railroads) and today (iPhones, Personal computers, etc.)
Marius was a legendary figure in Roman who held the role of Consul 7 times, defeated the Germanic invaders, and helped Rome become a power. He is credited with instituting a new recruitment system, which helped strengthen the Roman army.
