The completion of the ancient Suez Canal facilitated extending of the trade route from the western to the eastern borders of the empire. Because of such kind of amazing development, the commerce activity unfolded a prosperous phenomenon which also brought Persia enormous tax revenue. Also unlike Cyrus and Cambyses who were satisfied with the receiving gifts from their dependency. Darius II was concerned more about to build up a steady economic foundation.
It was a Corinthian dominion in the eight century. But it would come to the centre of the Peloponnesian War in the fifth century BC. It had vast amounts of minerals and rich farmland and the Athenians had poor farmland and a growing population and by adding Sicily to their empire would strengthen their status and help feed the growing population. Nikias was against the expedition of Sicily he thought it would be too costly in ships and men and resources and if they lost the battle it would be damaging to Athens and they would lose the war against Sparta if they lost the Sicily expedition while Alcibiades would eventually persuade the Athenian assembly to set sail for Sicily. Alcibiades was raised by the great Athenian politician and orator Pericles, but Pericles had no time to devote any attention to Alcibiades and this could explain why Alcibiades grew up selfish.
The Portuguese and the Spanish had a great deal of knowledge about the seas. Using charts and tables they figured out their latitude accurately, this allowed for more reliable return voyages to the Atlantic islands. Cannons were key to traveling on open waters. For a ship captain without any sort of protection, the sea could be a very dangerous place riddled with pirates. But cannons also affected city-states and countries; if one wanted to have successful navy large sums of money would need to be raised causing an increase in taxes and there would be an increase in need for shipwrights.
There were also many economic similarities between the Roman Empire and the Persian Empire. Both empires focused on improving their commerce. For example, Persia built a road system to help with their trade system. Rome traded using sea routes and roads that were protected from crime. Each empire had great wealth, which lead to architectural advancement.
Themistocles was responsible to a great extent for the Greek victory in the Persian wars. His role as both a political and military leader were crucial in the naval development of Athens and the Greek states, which allowed them to win the battle of the sea, resulting in a sense of confidence allowing them to be the victors of the final battles fought in Plataea and Mycale. Themistocles also played a vital role in both the battle of Artemisium and Salamis, which were significant to the overall Greek victory over the Persians. His political skills of oration proved of paramount importance in maintaining the Greek unity at Salamis as well as convincing Greek citizens to trust his tactics and methods, which evidently seized victory. The battle of Artemisium highlights Themistocles role in achieving victory for the Greeks.
This led the Roman´s expansion to all three of those regions. On the other hand, the Han could only spread further inland because of its geographical location. This was an important disvantage for the Han dynasty. When it comes to technology, both built roads to help support a growing dependence on trade. This helped both empires become as successful and powerful as they did.
The 'Radical Democracy' came about when Athens became more democratic with the introduction of a system of changes that allowed greater participation from ordinary citizens. By 508-07 BC, Athens was under the influence of Kleisthenes. He introduced a series of political reforms which turned Athens in a much more dramatic direction. One of the main results of Cleisthenes' reforms was to reduce the power of the upper classes. He did this by introducing the deme system.
Pericles and Ephialtes established pay for public officials, thus opening up offices to the poor. They did not do this simply because they had big hearts; they also knew that it would win the support of Athens's poor majority (which of course it did). Next Pericles and Ephialtes turned on the Areopagus, the Athenian high court; this, too, they opened to people of all classes. This move proved too much for the aristocrats, who had Ephialtes assassinated, but this act paved the way for Pericles to take
This is the most significant reason for our aggressive policy of expansion with political, economic, and military control as major objectives. We were looking for markets, which is the easiest way to colonize. In addition, investment opportunities like produce in Hawaii and certain mines in Philippines were noticed and desired. In Henry Cabot Lodge's "Our Blundering Foreign Policy," he reaffirms this point saying, "In the interests of our commerce and of our fullest development we should build the Nicaraguan canal, and ... for the sake of our commercial supremacy in the Pacific, we should control Hawaii and Samoa." The overseas territories were teeming with a cheap labor force, this would allow American goods to be made at a decreased cost.
