Satrap in the context of King Porus

Alcibiades (/ˌælsɪˈbaɪədiːz/; Ancient Greek: Ἀλκιβιάδης; c.450–404 BC) was an Athenian statesman and general. The last of the Alcmaeonidae, he played a major role in the second half of the Peloponnesian War as a strategic advisor, military commander, and politician, but subsequently fell from prominence.

During the course of the Peloponnesian War, Alcibiades changed his political allegiance several times. In his native Athens in the early 410s BC, he advocated an aggressive foreign policy and was a prominent proponent of the Sicilian Expedition. After his political enemies brought charges of sacrilege against him, he fled to Sparta, where he served as a strategic adviser, proposing or supervising several major campaigns against Athens. However, Alcibiades made powerful enemies in Sparta too, and defected to Persia. There he served as an adviser to the satrap Tissaphernes until Athenian political allies brought about his recall. He served as an Athenian general (strategos) for several years, but enemies eventually succeeded in exiling him a second time. He took refuge in Persian territory and was eventually assassinated, reportedly at the instigation of Sparta.

The siege of Naxos (499 BC) was a failed attempt by the Milesian tyrant Aristagoras, operating with support from, and in the name of the Persian Empire of Darius the Great, to conquer the island of Naxos. It was the opening act of the Greco-Persian Wars, which would ultimately last for 50 years.

Aristagoras had been approached by exiled Naxian aristocrats, who were seeking to return to their island. Seeing an opportunity to bolster his position in Miletus, Aristagoras sought the help of his overlord, the Persian king Darius the Great, and the local satrap, Artaphernes to conquer Naxos. Consenting to the expedition, the Persians assembled a force of 200 triremes under the command of Megabates.

The Ionian Revolt, and associated revolts in Aeolis, Doris, Cyprus and Caria, were military rebellions by several Greek regions of Asia Minor against Persian rule, lasting from 499 BC to 493 BC. At the heart of the rebellion was the dissatisfaction of the Greek cities of Asia Minor with the tyrants appointed by Persia to rule them, along with the individual actions of two Milesian tyrants, Histiaeus and Aristagoras. The cities of Ionia had been conquered by Persia around 540 BC, and thereafter were ruled by native tyrants, nominated by the Persian satrap in Sardis. In 499 BC, the tyrant of Miletus, Aristagoras, launched a joint expedition with the Persian satrap Artaphernes to conquer Naxos, in an attempt to bolster his position. The mission was a debacle, and sensing his imminent removal as tyrant, Aristagoras chose to incite the whole of Ionia into rebellion against the Persian king Darius the Great.

In 498 BC, supported by troops from Athens and Eretria, the Ionians marched on, captured, and burnt Sardis. However, on their return journey to Ionia, they were followed by Persian troops, and decisively beaten at the Battle of Ephesus. This campaign was the only offensive action by the Ionians, who subsequently went on the defensive. The Persians responded in 497 BC with a three-pronged attack aimed at recapturing the outlying areas of the rebellion, but the spread of the revolt to Caria meant that the largest army, under Daurises, relocated there. While initially campaigning successfully in Caria, this army was annihilated in an ambush at the Battle of Pedasus. This battle had started a stalemate for the rest of 496 BC and 495 BC.

The history of Persian Egypt refers to the two periods when ancient Egypt was controlled by the Achaemenid Empire:

• Twenty-seventh Dynasty of Egypt (525–404 BC), established by the first Achaemenid conquest of Egypt.
• Thirty-first Dynasty of Egypt (343–332 BC), established by the second Achaemenid conquest of Egypt.

These two periods of satrapies were punctuated by a brief interval of Egyptian independence from 404 BC to 343 BC.

The Ptolemaic dynasty (/ˌtɒlɪˈmeɪ.ɪk/; Ancient Greek: Πτολεμαῖοι, Ptolemaioi), also known as the Lagid dynasty (Λαγίδαι, Lagidai; after Ptolemy I's father, Lagus), was a Macedonian Greek royal house which ruled the Ptolemaic Kingdom in Ancient Egypt during the Hellenistic period. Reigning for 275 years, the Ptolemaic was the longest and last dynasty of ancient Egypt from 305 BC until its incorporation into the Roman Republic in 30 BC.

Ptolemy, a general and one of the somatophylakes (bodyguard companions) of Alexander the Great, was appointed satrap of Egypt after Alexander's death in 323 BC. In 305 BC he declared himself Pharaoh Ptolemy I, later known as Sōter "Saviour". The Egyptians soon accepted the Ptolemies as the successors to the pharaohs of independent Egypt. The new dynasty showed respect to local traditions and adopted the Egyptian titles and iconography, while also preserving their own Greek language and culture. The Ptolemaic period was marked by the intense interactions and blending of the Greek and Egyptian cultures. Under the Ptolemies, Hellenistic religion was largely shaped by religious syncretism and imperial cult. Elements of Greek education became widespread in urban spaces, culminating in the foundation of the Mouseion (including the Library of Alexandria) and the Serapeum. During the Hellenistic period, the city of Alexandria, founded by Alexander the Great, would gradually surpass Athens as the intellectual centre of the Mediterranean world.

The Parthian Empire (/ˈpɑːrθiən/), also known as the Arsacid Empire (/ˈɑːrsəsɪd/), was a major Iranian political and cultural power centered in ancient Iran from 247 BC to 224 AD. Its latter name comes from its founder, Arsaces I, who led the Parni tribe in conquering the region of Parthia in Iran's northeast, then a satrapy (province) under Andragoras, who was rebelling against the Seleucid Empire. Mithridates I (r. c. 171 – 132 BC) greatly expanded the empire by seizing Media and Mesopotamia from the Seleucids. At its height, the Parthian Empire stretched from the northern reaches of the Euphrates, in what is now central-eastern Turkey, to present-day Afghanistan and western Pakistan. The empire, located on the Silk Road trade route between the Roman Empire in the Mediterranean Basin and the Han dynasty of China, became a center of trade and commerce.

The Parthians largely adopted the art, architecture, religious beliefs, and regalia of their culturally heterogeneous empire, which encompassed Persian, Hellenistic, and regional cultures. For about the first half of its existence, the Arsacid court adopted elements of Greek culture, though it eventually saw a gradual revival of Iranian traditions. The Arsacid rulers were titled "King of Kings", claiming inheritance of the Achaemenid Empire; indeed, they accepted many local kings as vassals, although the Achaemenids would have had centrally appointed, albeit largely autonomous, satraps. The court did appoint a small number of satraps, largely outside Iran, but these satrapies were smaller and less powerful than the Achaemenid potentates. With the expansion of Arsacid power, the seat of central government shifted from Nisa to Ctesiphon along the Tigris (south of Baghdad), although several other sites also served as capitals.

Somatophylakes (Greek: Σωματοφύλακες; singular: somatophylax, σωματοφύλαξ) were the bodyguards of high-ranking people in ancient Greece.

The most famous body of somatophylakes were those of Philip II of Macedon and Alexander the Great. They consisted of seven men, drawn from the Macedonian nobility, who also acted as high-ranking military officers, holding command positions such as general or chiliarch. Alexander the Great appointed Peucestas as eighth somatophylax after the siege of Malli.

Antigonus I Monophthalmus (Ancient Greek: Ἀντίγονος Μονόφθαλμος Antigonos Monophthalmos, "Antigonus the One-Eyed"; 382 – 301 BC) was a Macedonian Greek general and successor of Alexander the Great. A prominent military leader in Alexander's army, he went on to control large parts of Alexander's former empire. He assumed the title of basileus (king) in 306 BC and reigned until his death. He was the founder of the Antigonid dynasty, which ruled over Macedonia until its conquest by the Roman Republic in 168 BC.

Antigonus likely served under Philip II of Macedon. He took part in Alexander's invasion of Achaemenid Persia and was named satrap of Phrygia. After Alexander's death in 323 BC, he also received Pamphylia and Lycia in accordance with the Partition of Babylon. However, he later incurred the enmity of Perdiccas, the regent of Alexander's empire, and was driven from Phrygia. He fled to Greece and formed an alliance with Antipater, later joined by Ptolemy, against Perdiccas. Perdiccas was murdered by his own officers in 320 BC, and Antipater was elected the new regent. During a series of wars between Alexander's successors, Antigonus briefly emerged as the most powerful of the Diadochi, ruling over Greece, Asia Minor, Syria, Phoenicia and northern Mesopotamia. Cassander, Seleucus, Ptolemy and Lysimachus formed a coalition against him, which culminated in his decisive defeat and death at the Battle of Ipsus in 301 BC. His kingdom was divided up by Lysimachus and Seleucus, but his son Demetrius survived and went on to seize control of Macedonia in 294 BC.

The Partition of Triparadisus was a power-sharing agreement passed at Triparadisus in 321 BC between the generals (Diadochi) of Alexander the Great, in which they named a new regent and arranged the repartition of the satrapies of Alexander's empire among themselves. It followed and modified the Partition of Babylon made in 323 BC upon Alexander's death.

Following the death of Alexander, the rule of his empire was given to his half-brother Philip Arrhidaeus and Alexander's son Alexander IV. However, since Philip was mentally ill and Alexander IV born only after the death of his father, a regent was named as Perdiccas; in the meantime, the former generals of Alexander were named satraps of the various regions of his empire.

Diodotus I Soter (Greek: Διόδοτος Σωτήρ, Diódotos Sōtḗr, "Diodotos the Savior"; c. 300 BC – c. 235 BC) was the first Hellenistic king of Bactria. Diodotus was initially satrap of Bactria, but became independent of the Seleucid empire around 255 BC, establishing the Greco-Bactrian Kingdom. In about 250 BC, Diodotus repelled a Parthian invasion of Bactria by Arsaces. He minted an extensive coinage and administered a powerful and prosperous new kingdom. He died around 235 BC and was succeeded by his son Diodotus II.

His rule was recounted by Apollodorus of Artemita in the Parthian History, but this text is lost, and surviving literary sources only mention him in passing. Thus, most details of Diodotus' life have to be reconstructed from numismatics and brief references by Justin and other historians.

Bactria (/ˈbæktriə/; Bactrian: βαχλο, Bakhlo), or Bactriana, was an ancient Iranian civilization in Central Asia, located in the area south of the Oxus River (modern Amu Darya) and north of the Hindu Kush mountains, within modern-day Afghanistan, Tajikistan and Uzbekistan. Bactria was strategically located south of Sogdia and west of the Pamir Mountains. These mountain ranges acted as "walls" protecting Bactria from three sides, with the Pamir mountains to the north and the Hindu Kush to the south forming a junction, and the Karakoram range towards the east.

Called "beautiful Bactria, crowned with flags" by the Avesta, the region is considered, in the Zoroastrian faith, to be one of the "sixteen perfect Iranian lands" that the supreme deity, Ahura Mazda, had created. It was once a small and independent kingdom struggling to survive against nomadic Turanians. One of the early centres of Zoroastrianism, and capital of the legendary Kayanian dynasty, Bactria is mentioned in the Behistun Inscription of Darius the Great as one of the satrapies of the Achaemenid Empire; it was a special satrapy, ruled by a crown prince or an intended heir. Bactria was the centre of Iranian resistance against the Greek Macedonian invaders after the fall of the Achaemenid Empire in the 4th century BC, but eventually fell to Alexander the Great.

Euthydemus I (Greek: Εὐθύδημος, Euthýdēmos, c. 260 BC – 200/195 BC) was a Greco-Bactrian king and founder of the Euthydemid dynasty. He is thought to have originally been a satrap of Sogdia, who usurped power from Diodotus II in 224 BC. Literary sources, notably Polybius, record how he and his son Demetrius resisted an invasion by the Seleucid king Antiochus III from 209 to 206 BC. Euthydemus expanded the Bactrian territory into Sogdia, constructed several fortresses, including the Derbent Wall in the Iron Gate, and issued a very substantial coinage.

The Caspians (Persian: کاسپی‌ها, Kaspyn; Greek: Κάσπιοι, Káspioi; Aramaic: ܟܣܦܝ, kspy; Old Armenian: Կասպք, Kaspk’; Latin: Caspi, Caspiani) were an people of antiquity who dwelt along the southwestern shores of the Caspian Sea, in the region known as Caspiane. Caspian is the English version of the Greek ethnonym Kaspioi, mentioned twice by Herodotus among the Achaemenid satrapies of Darius the Great and applied by Strabo. The name is not attested in Old Iranian.

The Caspians have generally been regarded as a pre-Indo-European people. They have been identified by Ernst Herzfeld with the Kassites, who spoke a language not identified with any other known language group and whose origins have long been the subject of debate. Onomastic evidence bearing on this point has been discovered in Aramaic papyri from Egypt published by P. Grelot, in which several of the Caspian names that are mentioned—and identified under the gentilic כספי kaspai—are, in part, etymologically Iranian. The Caspians of the Egyptian papyri are therefore generally considered as either an Iranian people or strongly under Iranian cultural influence.

The Twenty-seventh Dynasty of Egypt (notated Dynasty XXVII, alternatively 27th Dynasty or Dynasty 27), also known as the First Egyptian Satrapy (Old Persian: 𐎸𐎭𐎼𐎠𐎹, romanized: Mudrāya), was a satrapy of the Achaemenid Empire between 525 and 404 BC. It was founded by Cambyses II, the King of Persia, after the Battle of Pelusium (525 BC) and the Achaemenid conquest of Egypt, and his subsequent crowning as Pharaoh of Egypt. It 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 (343–332 BC).

A mausoleum is an external free-standing building constructed as a monument enclosing the burial chamber of a deceased person or people. A mausoleum without the person's remains is called a cenotaph. A mausoleum may be considered a type of tomb, or the tomb may be considered to be within the mausoleum.

The Saxons, sometimes called the Old Saxons or Continental Saxons, were a Germanic people of early medieval "Old" Saxony (Latin: Antiqua Saxonia) which became a Carolingian "stem duchy" in 804, in what is now northern Germany, between the lower Rhine and Elbe rivers. Many of their neighbours were, like them, speakers of West Germanic dialects, including both the Franks and Thuringians to the south, and the coastal Frisians and Angles to the north who were among the peoples who were originally referred to as "Saxons" in the context of early raiding and settlements in Roman Britain and Gaul. To their east were Obotrites and other Slavic-speaking peoples.

The political history of these continental Saxons is unclear until the 8th century and the conflict between their semi-legendary hero Widukind and the Frankish emperor Charlemagne. They do not appear to have been politically united until the generations of conflict leading up to that defeat, before which they were reportedly ruled by regional "satraps". Previous Frankish rulers of Austrasia, both Merovingian and Carolingian, fought numerous campaigns against Saxons, both in the west near the Lippe, Ems and Weser, and further east, near Thuringia and Bohemia, including the area which later medieval sources referred to as "North Swabia". Charlemagne conquered all the Saxons after winning the long Saxon Wars (772–804 AD) and forced them to convert to Christianity, annexing Saxony into the Carolingian domain. Under the Carolingian Franks, Saxony became a single duchy, fitting it within the basic political structure of the later Holy Roman Empire. The early rulers of this Duchy of Saxony expanded their territories—and therefore those of the Holy Roman Empire—to the east, at the expense of Slavic-speaking Wends.

Cyrus the Younger (Old Persian: 𐎤𐎢𐎽𐎢𐏁 Kūruš; Ancient Greek: Κῦρος Kyros; died 401 BC) was an Achaemenid prince and general. He ruled as satrap of Lydia and Ionia from 408 to 401 BC. Son of Darius II and Parysatis, he died in 401 BC in battle during a failed attempt to oust his elder brother, Artaxerxes II, from the Persian throne.

The history of Cyrus and of the retreat of his Greek mercenaries is told by Xenophon in his Anabasis. Another account, probably from Sophaenetus of Stymphalus, was used by Ephorus. Further information is contained in the excerpts from Artaxerxes II's physician, Ctesias, by Photius; Plutarch’s Lives of Artaxerxes II and Lysander; and Thucydides' History of Peloponnesian War. These are the only early sources of information on Cyrus the Younger.
