It is difficult to answer this questions as the term "powerful" is ambiguous. Furthemore, many eastern civilizations have not been researched well enough and may have been mor…e "powerful" than originally assumed. However, in terms of military power, it is generally accepted that Ancient Rome reach a level of military tactics and proweness far greated than anything else at the time. It's military tradition is said to be partly based on Macedonian and Spartan military traditions originating in the Hellenic world. In terms of science, the civilization which has most contributed overall to modern science, engineering and medicine, is Ancient Greece. This should not undermine the amazing advancements of other civilizations such as Ancient China, Egypt, Phoenicians etc.
The two most powerful officials in Rome were the consul.
In the wet, Rome. In the east, China.
Probably the Buddhism and Christianity.
Athens and Sparta were the two most powerful city-states in ancient Rome.
Aztec and Maya Civilizations.
The Ancient Hellenic (Greek) civilizations. They gave us the ideas of a republic and governance as well as learning and philosophy. They laid the foundations of modern science… and gave birth to modern maths, logic, and the concept of a mathematic proof. However the Greek civilization is said to have been greatly influenced in the beginning by Ancient Egypt. If we are looking at inventions many other civilizations have contributed such as Ancient China who gave us paper, gunpowder and many other. Mesopotamia gave us the wheel. It is difficult to say that one civilization was the most influential because most of them are interrelated. However it is generally accepted that Ancient Greece experienced a "Golden Age" during which extraordinary advancements where made in all the main aspects of modern civilization.
Most ancient civilizations built their societies around rivers (ex: Tigris, Euphrates, Yellow, Nile). They did this because rivers are fresh water and supply water to drink as… well as for irrigation (agriculture). Food and water supplies are a must for a civilization!
It depends what important means. In terms of contributions to the modern world, Ancient Greece contributed to Medicine, Science, Art, Engineering and Philosophy and laid the f…oundations of the Renaissance. However, the Golden Age of Ancient Greece has roots in Ancient Egypt. Rome was an outstanding military force but it's contributions to Art and Science are disproportionate to that of Greece and it is generally considered to have stalled advancements in these areas by conquering the Hellenic world. However the Romans had a contribution in Engineering. The Arabs took over Greece in Mathematics and advanced algebra. It really depends what you consider important. Important in what field? In terms of science and technology I would have to go with Greece.
Rome it was Mesopotamia for hundreds of years

Several of them, but the most important included the Aztec and Mayacivilizations.
In Roman Empire
The heritage of the so-called Byzantine Empire were the Greek and Roman civilisations. The Byzantine Empire was the continuation of the Roman Empire. This term has been coined… by historians to indicate the eastern part of the Roman Empire after the fall of the western part. This part of the Roman Empire continued to exist for nearly 1,000 years). The so-called "Byzantines" did not even know this term. They called their empire Imperium Romanum , Imperium Romanorum (Empire of the Romans) , or Romania in Latin or or Basileia Rhomaion, Arche ton Rhomaion or Rhomania , which were the same terms in Greek. The Term Romania was not related to the country which was later called Romania (it means land of the Romans). The term Byzantine was chosen by a German historian in the 16th century as a derivation from Byzantium, a Greek city which evolved along Roman lines under Roman rule and which was then redeveloped, turned into an imperial capital and renamed Constantinople (City of Constantine) by the Roman emperor Constantine the Great in 330. It is used to indicate the fact that not long after the fall of the western part of the Roman Empire, this part of the empire became centred on Greece and Greek in character after it lost most of its non-Greek territories. Greek replaced Latin as the official language of this empire in 620, some 150 years after the fall of the western part. Both the terms Byzantine and Byzantine Empire became common in Western Europe in the 19th century.
There were several civilizations that rose and fell in Mexico since 3000 BC. The first were the Olmecs, considered the progenitors of every other Mesoamerican civilization. Ot…her groups include the Teotihuacan, Zapotec, Toltec, Aztec and Maya; the two latter which were conquered by Spanish conquistadors in between the 16th and 18th centuries, transforming Mexico into an overseas territory of the Spanish Empire.
