Kingdom of Pergamon

(Redirected from Attalid dynasty)

The Kingdom of Pergamon, Pergamene Kingdom, or Attalid kingdom was a Greek state during the Hellenistic period that ruled much of the Western part of Asia Minor from its capital city of Pergamon. It was ruled by the Attalid dynasty (/ˈætəlɪd/; Greek: Δυναστεία των Ατταλιδών, romanizedDynasteía ton Attalidón).

The kingdom was a rump state that was created from the territory ruled by Lysimachus, a general of Alexander the Great. Philetaerus, one of Lysimachus' lieutenants, rebelled and took the city of Pergamon and its environs with him; Lysimachus died soon after in 281 BC. The new kingdom was initially in a vassal-like relationship of nominal fealty to the Seleucid Empire, but exercised considerable autonomy and soon became entirely independent. It was a monarchy ruled by Philetaerus's extended family and their descendants. It lasted around 150 years before being eventually absorbed by the Roman Republic during the period from 133–129 BC.


From autonomy to independence (282–241 BC)Edit

Philetaerus was a lieutenant of Lysimachus, one of Alexander the Great's generals (diadochi), who ruled a large state centered around Byzantium. Philetaerus was trusted to manage the fortress of Pergamon and guard much of Lysimachus's treasury, and had 9,000 talents under his purview. At some point prior to 281 BC, Philetaerus deserted Lysimachus and rebelled, allegedly over fears of Arsinoe, Lysimachus's wife, who was accused of arranging the death of Agathocles, Lysimachus's son. In 281 BC, Seleucus I Nicator, another of Alexander's generals, defeated and killed Lysimachus at the Battle of Corupedium, while Seleucus himself was killed a few months later. Philetaerus offered his services to Seleucus and his successors of the Seleucid Empire, but enjoyed considerable autonomy.[1] He extended his power and influence beyond just the city of Pergamon, making allies with neighboring city states. He contributed troops, money, and food to the city of Cyzicus, in Mysia, for its defense against the invading Gauls, thus gaining prestige and goodwill for him and his family.[2] He built the temple of Demeter on the acropolis, the temple of Athena (Pergamon's patron deity), and Pergamon's first palace. He added considerably to the city's fortifications.[2]

Philetaerus' nephew and adopted son, Eumenes I, succeeded him upon his death in 263 BC. He rebelled and defeated the Seleucid king Antiochus I Soter near the Lydian capital of Sardis in 261 BC. He freed Pergamon, and greatly increased its territories. He established garrisons, such as Philetaireia, in the north at the foot of Mount Ida, which was named after his adoptive father, and Attaleia, in the east, to the northeast of Thyatira near the sources of the river Lycus, which was named after his grandfather. He also extended his control to the south of the river Caïcus, reaching the Gulf of Cyme. He minted coins with the portrait of Philetaerus, who during his reign had still been depicting the Seleucid king Seleucus I Nicator on his coins.

Reign of Attalus I Soter (241–197 BC)Edit

Pausanias wrote that the greatest achievement of Attalus I (r. 241–197 BC) was his defeat of the Gauls,[3] by which he meant the Galatians, Celts who had migrated to central Asia Minor and established themselves as a major military power. Several years later the Galatians attacked Pergamon with the help of Antiochus Hierax, who rebelled against his brother, the Seleucid king Seleucus II Callinicus, and wanted to seize Asia Minor and make it his independent kingdom. Attalus defeated the Gauls and Antiochus in the Battle of Aphrodisium and in a second battle in the east. He then fought Antiochus alone in a battle near Sardis and in the Battle of the Harpasus in Caria in 229 BC. After this Antiochus left to start a campaign in Mesopotamia, and then pivoted toward Thrace in 227 BC. He was killed in battle against the Gauls and the Kingdom of Tylis.[4] With Antiochus Hierax's death, Attalus gained control over all Seleucid territories in Asia Minor north of the Taurus Mountains. He repulsed several attempts by Seleucus III Ceraunus, who had succeeded Seleucus II, to recover the lost territory.[4]

In 223 BC, Seleucus III crossed the Taurus, but was assassinated, and the general Achaeus assumed control of the army. Antiochus III the Great made Achaeus governor of the Seleucid territories north of the Taurus. Within two years Achaeus had recovered the lost territories and forced Attalus to retreat within the walls of Pergamon. However, Achaeus himself turned on Antiochus III and proclaimed himself a king, perhaps because he was accused of intending to revolt anyway, or perhaps simply drunk with success. By 220/219 BC, Achaeus and Attalus seem to have made peace.[5][6][7]

In 218 BC, Achaeus undertook an expedition to Selge, south of the Taurus. Attalus recaptured his former territories with the help of some Thracian Gauls. Achaeus returned from his victorious campaign in 217 BC and hostilities between the two resumed. Attalus made an alliance with Antiochus III, who besieged Achaeus in Sardis in 214 BC. Antiochus captured the city and put Achaeus to death in the next year. Attalus regained control over his territories.[5][8]

The Attalids became allies of the Roman Republic during the First Macedonian War (214–205 BC).[9] They would go on to support Rome in many subsequent wars. Attalus I, who had helped the Romans in the first war, also provided them with assistance in the Second Macedonian War (200–197 BC).[10][11]

Expansion after the Treaty of Apamea (197–138 BC)Edit

King Antiochus III of the Seleucids seem to have conquered or at least cowed into neutrality much of Pergamese territory in 198; by 196, at least, it seems that Antiochus III was able to march his armies through the area without opposition, and important putatively Attalid cities such as Phocaea and Thyatira were in Seleucid possession.[12] The authority of the Pergamese state was hanging by a thread when Eumenes II (r. 197–159 BC)[13] came to the throne in 197 BC. Eumenes II sought alliances with the Achaean League and supported Rome in the Roman–Seleucid War of 192–188 BC.[14][15] In 188 BC, after the war's end by the Treaty of Apamea, the Romans seized the possessions of the defeated Antiochus III in Asia Minor and gave Mysia, Lydia, Phrygia, and Pamphylia to the kingdom of Pergamon and Caria, Lycia and Pisidia, in the southwestern corner of Asia Minor, to Rhodes, another Roman ally. Later the Romans gave these possessions of Rhodes to Pergamon. These acquisitions were an enormous increase in the size and influence of Pergamon. During the reign of Eumenes II, the Pergamese would also fight the Galatian War, Prusias I of Bithynia (around 188–184 BC?), Pharnaces I of Pontus (around 183-179 BC?), and would aid the Romans again in the Third Macedonian War (171–168 BC).[14][16] Eumenes II also successfully intervened in Seleucid politics, aiding Antiochus IV Epiphanes in his quest to take the throne from Heliodorus.[14]

Eumenes II was ill for the last decade of his life, and was succeeded by his brother Attalus II as king in 159 BC, although Attalus II had already assumed many key responsibilities by then. Before he became king, he was a military commander. In 190 BC he took part in the Battle of Magnesia, which was the final victory of the Romans in the war against the Seleucids. In 189 BC he led the Pergamene troops which flanked the Roman army under Gnaeus Manlius Vulso in the Galatian War. He was the lead commander in the war with Pontus, as well. After becoming king in his own right, he made war against Prusias II of Bithynia in 156–154 BC with the help of the Romans. In 154 BC he was also assisted by Ariarathes V of Cappadocia, who provided troops led by his son Demetrius. Attalus expanded his kingdom and founded the cities of Philadelphia and Attalia. In 152 BC the two kings and Rome helped and funded Alexander Balas in his succesful bid to start a civil war in the Seleucid Empire and to seize the Seleucid throne from Demetrius I Soter. In 149 BC, Attalus helped Nicomedes II Epiphanes to seize the Bithynian throne from his father Prusias II.[17] Attalus II also aided the Romans in the Fourth Macedonian War, the final war that destroyed Macedonia as a political force.[18]

Final years (138–129 BC)Edit

Not that much has survived in ancient sources of the reign of the last Attalid king, Attalus III; they tend to focus on his personal character rather than describe events during his reign. He seems to have continued to defend the empire militarily and to have funded various cults and religious works. He did not have any children, and bequeathed his kingdom to the Roman Republic in his will with his death in 133 BC.[19][20] The Romans were reluctant to take on territory in Asia Minor and did not take charge of the kingdom. A man named Aristonicus, claiming to be the illegitimate son of Eumenes II, assumed the dynastic name of Eumenes II, attempted to overturn Attalus III's will, and apparently acquired authority at least in the core Pergamese cities. In 131 BC Rome sent an army against him which was defeated. However, a second force defeated Eumemes III in 129 BC. They annexed the former kingdom of Pergamon, which became the Roman province of Asia.

Art and cultureEdit

In the interior of the Pergamon Altar there is a frieze depicting the life of Telephus, son of the demigod Herakles. The ruling dynasty associated Telephus with its city and used him to claim descent from the Olympians. Pergamon, having entered the Greek world much later than its counterparts to the west, could not boast the same divine heritage as older city-states and so had to cultivate its place in Greek mythology retroactively.
