WThe Achaemenid conquest of Egypt took place in 525 BCE, leading to the foundation of the Twenty-seventh Dynasty of Egypt, also known as the "First Egyptian Satrapy". Egypt thus became a province (satrapy) of the Achaemenid Persian Empire until 404 BCE while still maintaining Egyptian royalty customs and positions. The conquest was led by Cambyses II, the King of Persia, who defeated the Egyptians at the Battle of Pelusium, and crowned himself as Pharaoh of Egypt. Achaemenid rule was disestablished upon the rebellion and crowning of Amyrtaeus as Pharaoh. A second period of Achaemenid rule in Egypt occurred under the Thirty-first Dynasty of Egypt.
WThe Cadusian Campaign was a military campaign of King Artaxerxes II of Persia in 385 BC against the Cadusii. The origins of the campaign are not attested in historical sources, but it was probably in response to a revolt of the Cadusii and the refusal of paying tribute.
WThe Corinthian War was an ancient Greek conflict lasting from 395 BC until 387 BC, pitting Sparta against a coalition of Thebes, Athens, Corinth and Argos, backed by the Achaemenid Empire. The immediate cause of the war was a local conflict in northwest Greece in which Thebes and Sparta intervened. The deeper cause was hostility towards Sparta, provoked by that city's "expansionism in Asia Minor, central and northern Greece and even the west". The Corinthian War followed the Peloponnesian War, in which Sparta had achieved hegemony over Athens and its allies.
WThe first Persian invasion of Greece, during the Persian Wars, began in 492 BC, and ended with the decisive Athenian victory at the Battle of Marathon in 490 BC. The invasion, consisting of two distinct campaigns, was ordered by the Persian king Darius the Great primarily in order to punish the city-states of Athens and Eretria. These cities had supported the cities of Ionia during their revolt against Persian rule, thus incurring the wrath of Darius. Moreover, Athens was part of the persian empire since Kleisthenes gave them soil and water, for their protection against the invading spartan army, summoned by Isocrates. Darius also saw the opportunity to extend his empire into Europe, and to secure its western frontier.
WThe Greco-Persian Wars were a series of conflicts between the Achaemenid Empire and Greek city-states that started in 499 BC and lasted until 449 BC. The collision between the fractious political world of the Greeks and the enormous empire of the Persians began when Cyrus the Great conquered the Greek-inhabited region of Ionia in 547 BC. Struggling to control the independent-minded cities of Ionia, the Persians appointed tyrants to rule each of them. This would prove to be the source of much trouble for the Greeks and Persians alike.
WThe Achaemenid conquest of the Indus Valley refers to the Achaemenid military conquest and governance of the territories of the North-western regions of the Indian subcontinent, from the 6th to 4th centuries BCE. The conquest occurred in two phases. The first invasion was conducted around 535 BCE by Cyrus the Great, who founded the Achaemenid Empire. Cyrus annexed the regions west of the Indus River, which formed the eastern border of his empire. Following the death of Cyrus, Darius the Great established his dynasty and began to reconquer former provinces and further expand the extent of the empire. Around 518 BCE Darius crossed the Himalayas into India to initiate a second period of conquest by annexing regions up to the Jhelum River in Punjab.
WThe Peloponnesian War was an ancient Greek war fought between the Delian League, which was led by Athens; and the Peloponnesian League, which was led by Sparta. Historians have traditionally divided the war into three phases. In the first phase, the Archidamian War, Sparta launched repeated invasions of Attica, while Athens took advantage of its naval supremacy to raid the coast of the Peloponnese and attempt to suppress signs of unrest in its empire. This period of the war was concluded in 421 BC, with the signing of the Peace of Nicias. That treaty, however, was soon undermined by renewed fighting in the Peloponnese. In 415 BC, Athens dispatched a massive expeditionary force to attack Syracuse, Sicily; the attack failed disastrously, with the destruction of the entire force in 413 BC. This ushered in the final phase of the war, generally referred to either as the Decelean War, or the Ionian War. In this phase, Sparta, now receiving support from the Achaemenid Empire, supported rebellions in Athens's subject states in the Aegean Sea and Ionia, undermining Athens's empire, and, eventually, depriving the city of naval supremacy. The destruction of Athens's fleet in the Battle of Aegospotami effectively ended the war, and Athens surrendered in the following year. Corinth and Thebes demanded that Athens should be destroyed and all its citizens should be enslaved, but Sparta refused.
WThe Scythian campaign of Darius I was a military expedition into parts of European Scythia by Darius I, the king of the Achaemenid Empire, in 513 BC. The Scythians were an East Iranian-speaking people who had invaded Media, revolted against Darius and threatened to disrupt trade between Central Asia and the shores of the Black Sea as they lived between the Danube and Don Rivers and the Black Sea. The campaigns took place in parts of what is now the Balkans, Ukraine and southern Russia.
WThe second Persian invasion of Greece occurred during the Greco-Persian Wars, as King Xerxes I of Persia sought to conquer all of Greece. The invasion was a direct, if delayed, response to the defeat of the first Persian invasion of Greece at the Battle of Marathon, which ended Darius I's attempts to subjugate Greece. After Darius's death, his son Xerxes spent several years planning for the second invasion, mustering an enormous army and navy. The Athenians and Spartans led the Greek resistance. About a tenth of the Greek city-states joined the 'Allied' effort; most remained neutral or submitted to Xerxes.
WThe wars of Alexander the Great were a series of wars, fought over a span of thirteen years, that were carried out by King Alexander III of Macedon. The wars began with the battles against the Achaemenid Persian Empire under the rule of former King Darius III. After Alexander's chain of victories against Persia, he then began to skirmish with local chieftains and warlords stretching as far as modern-day Punjab, India. By the time of his death, he was emperor over most regions of Greek culture and the conquered Persian Empire. He did not manage to conquer all of South Asia as was his initial plan. Although he was a very successful military commander, he did not provide any stable alternative to the Achaemenid Empire, and his untimely death threw the vast territories he conquered into civil war.
