Answer:
The Civil War had a greater impact on American society and the polity than any other event in the country's history. It was also the most traumatic experience endured by any generation of Americans. At least more than 600,000 soldiers lost their lives in the war, at least 2% of the American population in 1861.
<span>A) Nationalism prevented the countries from uniting </span>
Throughout the Arab region, a strong nationalist sentiment opposed
foreign control. This led to emergence of nationalist organizations as the
National Party in Egypt, the Young Ottomans and then the Young Turks in the
Ottoman Empire. Different nationalist groups had different ideas of the future
of their countries and about how national communities ought to be formed.
While both Greek and Romans were pretty ethnocentric by modern standards, the Romans assimilated far more people into their institutional lives.
Many non-Greeks adopted Gteek lifestyles, language and habits after the age of Alexander, but the cross-pollination was more frequently cultural than political. Cleopatra might have dressed like an Egyptian queen and patronized the Egyptian gods, but she wouldn't have had Egyptian generals or Egyptian judges. The Greeks tended to settle into the cultures they occupied like the British in India: remaining separate from and believing themselves superior to the people around them, even while encouraging the 'natives' to adopt their culture habits.
Romans did a much more thorough job assimilating the peoples they conquered. Non-Romans could and did become citizens, even from very early times. This started with neighboring groups like the Latins, but eventually extend to the rest of Italy and later to the whole empire. Eventually there would be "Roman" emperors of Syrian, British, Spanish, Gallic, Balkan, and North African descent Farther down the social scale the mixing was much more complete (enough to irritate many Roman traditionalists). This wasn’t just a practical accommodation, either — when emperor Claudius allowed Gauls into the Roman Senate he pointed out that by his time the Romans had been assimilating former enemies since the days of Aeneas.
