Query: How long did the Ptolemaic dynasty last?
The Ptolemaic army was the army of the Ptolemaic Macedonian kings that ruled Egypt from 305 to 30 BC. Like most of the other armies of the Diadochi, it was very much Macedonian in style, with the use of the long pike ("sarissa") in a deep phalanx formation. Despite the strength of the Ptolemaic army, evinced in 217 BC with the victory over the Seleucids at the Battle of Raphia, the Ptolemaic kingdom itself fell into decline and by the time of Julius Caesar, it was but a mere client-kingdom of the Roman Republic. The army by the time of Caesar’s campaigns in the eastern Mediterranean was a mere shadow of its former self: generally, a highly disorganized assemblage of mercenaries and other foreign troops.
Some writers have questioned whether the Roman pyramids were modelled on the much less steeply pointed Egyptian pyramids exemplified by the famous pyramids of Giza. However, the relatively shallow Giza-type pyramids were not exclusively used by the Egyptians; steeper pyramids of the Nubian type were favoured by the Ptolemaic dynasty of Egypt that had been brought to an end in the Roman conquest of 30 BC. The pyramid was, in any case, built during a period when Rome was going through a fad for all things Egyptian. The Circus Maximus was adorned by Augustus with an Egyptian obelisk, and pyramids were built elsewhere in the Roman Empire around this time; the Falicon pyramid near Nice in France was suspected by some to have been constructed by Roman legionaries who followed an Egyptian cult, but more recent research has indicated that it was actually built between 1803 and 1812.
Soon after the Sumerian civilization began, the Nile valley of Lower and Upper Egypt was unified under the Pharaohs approximately around 3150 BC. Since then, Ancient Egypt experienced 3 high points of civilization, the so-called "Kingdom" periods:
The history of Ancient Egypt is concluded by the Late Period (664–332 BC), immediately followed by the history of Egypt in Classical Antiquity, beginning with Ptolemaic Egypt.
Hypatia (born 350–370; died 415 AD) was a Hellenistic Neoplatonist philosopher, astronomer, and mathematician, who lived in Alexandria, Egypt, then part of the Eastern Roman Empire. She was a prominent thinker of the Neoplatonic school in Alexandria, where she taught philosophy and astronomy. She is the first female mathematician whose life is reasonably well recorded. Hypatia was renowned in her own lifetime as a great teacher and a wise counselor. She is known to have written a commentary on Diophantus's thirteen-volume "Arithmetica", which may survive in part, having been interpolated into Diophantus's original text, and another commentary on Apollonius of Perga's treatise on conic sections, which has not survived. Many modern scholars also believe that Hypatia may have edited the surviving text of Ptolemy's "Almagest", based on the title of her father Theon's commentary on Book III of the "Almagest".
The first dynasty of the Persian Empire was created by Achaemenids, established by Cyrus the Great in 550 BC with the conquest of Median, Lydian and Babylonian empires. It covered much of the Ancient world when it was conquered by Alexander the Great. Persepolis is the most famous historical site related to Persian Empire in the Achaemenid era and it has been a UNESCO World Heritage Site since 1979.
The historical records of ancient Egypt begin with Egypt as a unified state, which occurred sometime around 3150 BC. According to Egyptian tradition, Menes, thought to have unified Upper and Lower Egypt, was the first king. This Egyptian culture, customs, art expression, architecture, and social structure was closely tied to religion, remarkably stable, and changed little over a period of nearly 3000 years.
The decades that followed became known as the Golden Age of Athenian democracy, during which time Athens became the leading city of Ancient Greece, with its cultural achievements laying the foundations for Western civilization. The playwrights Aeschylus, Sophocles and Euripides flourished in Athens during this time, as did the historians Herodotus and Thucydides, the physician Hippocrates, and the philosopher Socrates. Guided by Pericles, who promoted the arts and fostered democracy, Athens embarked on an ambitious building program that saw the construction of the Acropolis of Athens (including the Parthenon), as well as empire-building via the Delian League. Originally intended as an association of Greek city-states to continue the fight against the Persians, the league soon turned into a vehicle for Athens's own imperial ambitions. The resulting tensions brought about the Peloponnesian War (431–404 BC), in which Athens was defeated by its rival Sparta.
Diocletian was the first Emperor to divide the Roman Empire into a Tetrarchy. In 286 he elevated Maximian to the rank of "augustus" (emperor) and gave him control of the Western Empire while he himself ruled the East. In 293, Galerius and Constantius Chlorus were appointed as their subordinates (caesars), creating the First Tetrarchy. This system effectively divided the Empire into four major regions, as a way to avoid the civil unrest that had marked the 3rd century. In the West, Maximian made Mediolanum (now Milan) his capital, and Constantius made Trier his. In the East, Galerius made his capital Sirmium and Diocletian made Nicomedia his. On 1 May 305, Diocletian and Maximian abdicated, replaced by Galerius and Constantius, who appointed Maximinus II and Valerius Severus, respectively, as their caesars, creating the Second Tetrarchy.
The Sassanid Empire is the name used for the fourth Iranian dynasty, and the second Persian Empire (226–651). The empire's territory encompassed all of today's Iran, Iraq, Armenia, Afghanistan, eastern parts of Turkey, and parts of Syria, Pakistan, and large parts of Caucasia, Central Asia and Arabia. During Khosrow II's rule in 590–628 Egypt, Jordan, Palestine, Lebanon were also briefly annexed to the Empire, as well as far west as western Asia Minor. The Sassanid era, encompassing the length of the Late Antiquity period, is considered to be one of the most important and influential historical periods in Iran. In many ways the Sassanid period witnessed the highest achievement of Persian civilization. The empire is furthermore known for being the arch-rival of the neighboring Roman–Byzantine Empire for a period of over 400 years. As the Parthians were replaced by the Sassanids, they carried on the already century long lasting Roman–Persian Wars, which would eventually become the longest conflict in human history.
The Academy (Ancient Greek: Ἀκαδημία) was founded by Plato (428/427 BC – 348/347 BC) in c. 387 BC in Athens. Aristotle (384–322 BC) studied there for twenty years (367–347 BC) before founding his own school, the Lyceum. The Academy persisted throughout the Hellenistic period as a skeptical school, until coming to an end after the death of Philo of Larissa in 83 BC. The Platonic Academy was destroyed by the Roman dictator Sulla in 86 BC.
Modern historians' dates for the war have been hotly debated, with no clear consensus. It is generally accepted that the war lasted 10 years, and ended in summer 346 BC (one of the few firm dates), which yields a date of 356 BC for the beginning of the war, with Philomelos's seizure of Delphi. Diodorus's chronology for the sacred war is very confused—he dates the start and end of the war a year too late, variously says the war lasted 9, 10 or 11 years, and included the siege of Methone twice under different dates—and his dates cannot therefore be relied upon.
According to Cleomedes' "On the Circular Motions of the Celestial Bodies", around 240 BC, Eratosthenes, the librarian of the Library of Alexandria, calculated the circumference of the Earth in Ptolemaic Egypt. Using a scaphe, he knew that at local noon on the summer solstice in Syene (modern Aswan, Egypt), the Sun was directly overhead. (Syene is at latitude 24°05′ North, near to the Tropic of Cancer, which was 23°42′ North in 100 BC) He knew this because the shadow of someone looking down a deep well at that time in Syene blocked the reflection of the Sun on the water. He then measured the Sun's angle of elevation at noon in Alexandria by using a vertical rod, known as a gnomon, and measuring the length of its shadow on the ground. Using the length of the rod, and the length of the shadow, as the legs of a triangle, he calculated the angle of the sun's rays. This angle was about 7°, or 1/50th the circumference of a circle; taking the Earth as perfectly spherical, he concluded that the Earth's circumference was 50 times the known distance from Alexandra to Syene (5,000 stadia, a figure that was checked yearly), i.e. 250,000 stadia. Depending on whether he used the "Olympic stade" (176.4m) or the Italian stade (184.8m), this would imply a circumference of 44,100 km (an error of 10%) or 46,100 km, an error of 15%. In 2012, Anthony Abreu Mora repeated Eratosthenes's calculation with more accurate data; the result was 40,074 km, which is 66 km different (0.16%) from the currently accepted polar circumference.
The Classical Greek historians Herodotus and Thucydides reported the legend that the Macedonian kings of the Argead dynasty were descendants of Temenus, king of Argos, and could therefore claim the mythical Heracles as one of their ancestors as well as a direct lineage from Zeus, chief god of the Greek pantheon. Contradictory legends state that either Perdiccas I of Macedon or Caranus of Macedon were the founders of the Argead dynasty, with either five or eight kings before AmyntasI. The assertion that the Argeads descended from Temenus was accepted by the "Hellanodikai" authorities of the Ancient Olympic Games, permitting Alexander I of Macedon () to enter the competitions owing to his perceived Greek heritage. Little is known about the kingdom before the reign of AlexanderI's father Amyntas I of Macedon () during the Archaic period.
Before its establishment as a Republic, Rome was ruled by kings (Latin "reges", singular "rex"). In Roman tradition, Rome's founder Romulus was the first. Servius Tullius was the sixth, and his successor Tarquinius Superbus (Tarquin the Proud) was the last. The nature of Roman kingship is unclear; most Roman kings were elected by the senate, as to a lifetime magistracy, but some claimed succession through dynastic or divine right. Some were native Romans, others were foreign. Later Romans had a complex ideological relationship with this distant past. In Republican mores and institutions kingship was abhorrent; and remained so, in name at least, during the Empire. On the one hand, Romulus was held to have brought Rome into being more-or-less at a stroke, so complete and purely Roman in its essentials that any acceptable change or reform thereafter must be clothed as restoration. On the other, Romans of the Republic and Empire saw each king as contributing in some distinctive and novel way to the city's fabric and territories, or its social, military, religious, legal or political institutions. Servius Tullius has been described as Rome's "second founder", "the most complex and enigmatic" of all its kings, and a kind of "proto-Republican magistrate".
In Ancient Egypt the Bronze Age begins in the Protodynastic period, BC. The archaic "early Bronze Age of Egypt", known as the Early Dynastic Period of Egypt, immediately follows the unification of Lower and Upper Egypt, BC. It is generally taken to include the First and Second Dynasties, lasting from the Protodynastic Period of Egypt until about 2686 BC, or the beginning of the Old Kingdom. With the First Dynasty, the capital moved from Abydos to Memphis with a unified Egypt ruled by an Egyptian god-king. Abydos remained the major holy land in the south. The hallmarks of ancient Egyptian civilization, such as art, architecture and many aspects of religion, took shape during the Early Dynastic period. Memphis in the Early Bronze Age was the largest city of the time.
The Old Kingdom of the regional Bronze Age is the name given to the period in the 3rd millennium BC when Egypt attained its first continuous peak of civilization in complexity and achievement – the first of three "Kingdom" periods, which mark the high points of civilization in the lower Nile Valley (the others being Middle Kingdom and the New Kingdom).
Diogenes Laërtius divided the history of the Academy into three: the Old, the Middle, and the New. At the head of the Old he put Plato, at the head of the Middle Academy, Arcesilaus, and of the New, Lacydes. Sextus Empiricus enumerated five divisions of the followers of Plato. He made Plato founder of the first Academy; Arcesilaus of the second; Carneades of the third; Philo and Charmadas of the fourth; and Antiochus of the fifth. Cicero recognised only two Academies, the Old and New, and had the latter commence with Arcesilaus.
This is a family tree for the Zhou dynasty, descendants of Duke Wu of Zhou who overthrew the last Shang ruler, thereby establishing the dynasty. Ruling from 1046 BC to 256 BC, it is notable as the longest dynasty in Chinese history, although the actual political and military control of China by the dynasty only lasted during the Western Zhou.
The Qin dynasty () was the first dynasty of Imperial China, lasting from 221 to 206 BC. Named for its heartland in Qin state (modern Gansu and Shaanxi), the dynasty was founded by Qin Shi Huang, the First Emperor of Qin. The strength of the Qin state was greatly increased by the Legalist reforms of Shang Yang in the fourth century BC, during the Warring States period. In the mid and late third century BC, the Qin state carried out a series of swift conquests, first ending the powerless Zhou dynasty, and eventually conquering the other six of the Seven Warring States. Its 15 years was the shortest major dynasty in Chinese history, consisting of only two emperors, but inaugurated an imperial system that lasted, with interruption and adaptation, until 1912 CE.
The constitutional history of the Roman Republic can be divided into five phases. The first phase began with the revolution which overthrew the Roman Kingdom in 510 BC, and the final phase ended with the revolution which overthrew the Roman Republic, and thus created the Roman Empire, in 27 BC. Throughout the history of the republic, the constitutional evolution was driven by the struggle between the aristocracy (the "Patricians") and the ordinary citizens (the "Plebeians"). Approximately two centuries after the founding of the republic, the Plebeians attained, in theory at least, equality with the Patricians. In practice, however, the plight of the average Plebeian remained unchanged. This set the stage for the civil wars of the 1st century BC, and Rome's transformation into a formal empire.
In the mid-5th century BC, when the Athenian Acropolis became the seat of the Delian League and Athens was the greatest cultural centre of its time, Pericles initiated an ambitious building project that lasted the entire second half of the century. The most important buildings visible on the Acropolis today — the Parthenon, the Propylaia, the Erechtheion and the temple of Athena Nike — were erected during this period. The Parthenon was built under the general supervision of the artist Phidias, who also had charge of the sculptural decoration. The architects Ictinos and Callicrates began their work in 447 BC, and the building was substantially completed by 432, but work on the decorations continued until at least 431.
The emergence of the Mitanni c. 1500 BC eventually led to a short period of sporadic Mitanni domination c. 1450 BC. The Indo-European-language-family-speaking Mitanni are thought to have conquered and formed the ruling class over the indigenous Hurrians in eastern Anatolia. The Hurrians had spoken a language isolate, one neither of the Afroasiatic language family nor the Indo-European language family.) There are dozens of Mesopotamian cuneiform texts from this period, with precise observations of solar and lunar eclipses, that have been used as "anchors" in the various attempts to define the chronology of Babylonia and Assyria between c. 2000 BC – c. 1300 BC.)
The last ruler from the Ptolemaic dynasty was Cleopatra, who committed suicide following the burial of her lover Mark Antony, who had died in her arms (from a self-inflicted stab wound) after Augustus had captured Alexandria and her mercenary forces had fled.
Dates in brackets represent the regnal dates of the Ptolemaic pharaohs. They frequently ruled jointly with their wives, who were often also their sisters. Several queens exercised regal authority. Of these, one of the last and most famous was Cleopatra ("Cleopatra VII Philopator", 51–30 BC), with her two brothers and her son serving as successive nominal co-rulers. Several systems exist for numbering the later rulers; the one used here is the one most widely employed by modern scholars.
In 525 B.C., the political state of Egypt was taken over by the Persians, almost a century and a half into Egypt's Late Period. By 404 B.C., the Persians were expelled from Egypt starting a short period of independence. These 60 years of Egyptian rule consisted of an abundance of usurpers and short reigns. Again the Egyptians were plagued with Persians as they conquered Egypt again until 332 B.C.with the arrival of Alexander the Great. Sources state that were cheering when Alexander entered the capital since he drove out the immensely disliked Persians. The Late Period is marked with the death of Alexander the Great and the start of the Ptolemaic Dynasty. Although this period marks political turbulence an immense change for Egypt, its art and culture continued to flourish.
Starting with the Thirtieth Dynasty, the fifth dynasty in the Late Period, and extending into the Ptolemaic era. These temples ranged from the Delta to the island of Philae. While Egypt was outside fluencies through trade and conquered by foreign states, these temples were still in the traditional Egyptian style with very little Hellenistic influence.
Ptolemy's family ruled Egypt until the Roman conquest of 30 BC. All the male rulers of the dynasty took the name Ptolemy. Ptolemaic queens, some of whom were the sisters of their husbands, were usually called Cleopatra, Arsinoe, or Berenice. The most famous member of the line was the last queen, Cleopatra VII, known for her role in the Roman political battles between Julius Caesar and Pompey, and later between Octavian and Mark Antony. Her suicide at the conquest by Rome marked the end of Ptolemaic rule in Egypt though Hellenistic culture continued to thrive in Egypt throughout the Roman and Byzantine periods until the Muslim conquest.
