Though Seleucus' rule is an uneventful period of recovery, the heavy taxation needed to pay the
indemnity to Rome doesn't help Seleucid popularity. Rome insists that
Antiochus the younger son of Antiochus III be replaced as hostage in Rome
by Demetrius,
the eldest son of Seleucus and his heir. Antiochus takes his time returning
home and ends up in Athens where he (successfully) runs for election.
Antiochus, on hearing of his brother Seleucus' murder, leaves Athens and sails
for Pergamon. Then with Pergamonese help he seizes power in
Syria. The claim of Demetrius, the eldest son of Seleucus
and still a hostage in Rome, is quietly forgotten.
Demetrius, the son of Seleucus and his true heir, escapes from Rome,
lands at Tripolis
and proclaims himself King. Lysias' rule collapses and the mutinous
troops murder Antiochus V at Demetrius' request: "let me not see their faces".
The histories tell us that the Atiochenes soon become disillusioned
with the dour Demetrius but it is enemies abroad that bring him down.
After a botched attempt by Demetrius to secure his own claimant on the throne of
Capidocia Pergamon and Ptolemaic Egypt combine against him backing
Alexander Balas, the supposed son of Antiochus Epiphanes. Alexander
establishes
a base at Ptolemais and Demetrius is killed in the fighting.
Alexander is married off to Cleopatra Thea, the daughter of Ptolemy
Philometor (King of Egypt). Three years pass while Balas enjoys his
Kingdom but now Demetrius ( all of 14 years old), son of Demetrius Sotor arrives with the backing
of a bunch of Cretan mercenaries led by Lasthenes. Ptolemy comes to Ballas'
aid (and just happens
to spend time capturing the cities of Palestine that Egypt has always
considered it's inheritance). Ballas, who can do without such 'help',
attempts to assassinate Ptolemy (or is Ballas being
framed to cover Ptolemy's betrayal?).
Ballas flees to Cilicia and the Atiochenes proclaim Ptolemy as King.
Knowing that Rome will not permit this he persuades Antioch to accept Demetrius
who marries Cleopatra Thea.
Balas makes one last play but is defeated and killed but Ptolemy
is mortally wounded. Lasthenes gets Demetrius to order a massacre of
the leaderless Ptolemid army. The Jewish leader Johnathan is bought off
by a grant of autonomy. Lasthenes knowing that the native
Greek soldiery is a threat to his position orders them to be disarmed. Antioch
rises against Demetrius but the rising is brutally put down by the Cretan
mercenaries and Jewish troops sent by Johnathan.
Antioch is looted and with a large part of the city destroyed by fire is
cowed but nemesis is at hand.Diodotus proclaims the son of Balas, Antiochus, as King. Antioch and most of inland Syria joins him. The civil war drags on and within three years Antiochus has died of "illness" and Diodotus has proclaimed himself King as Tryphon. In an attempt to break the deadlock Demetrius by passes Tryphon and enters Mesopotamia in an attempt to recapture it from the Pathians. Though initially successful he is soon captured by the Pathians.
Antiochus, Demetrius's younger brother is proclaimed King and
marries (you've guessed it) Cleopatra Thea. He defeats Tryphon. He then
moves on Jerusalem and ends (for the moment) Jewish independence.
By 130 BCE he is ready to take on Parthia and reconquers Babylonia.
The desperate Parthian King releases Demetrius Nicator (bad move) and
stirs revolt amongst Antiochus' new conquests who do not find Seleucid
taxes to their liking (good move). Antiochus is completely wrong footed
by the revolt and is caught, heavily outnumbered, by the Parthian
main army and killed. The Parthian king immediately sends cavalry
to recapture Demetrius but too late.
Demetrius arrives in Syria at the same time as news of Antiochus' death
and regains both his throne and his wife Cleopatra Thea.
(Cleopatra has however taken the precaution to send her son
by Sidetes, Antiochus, to Cyzicus in Asia Minor.) After a
botched invasion of Egypt by Demetrius, Ptolemy Euergetes discovers
a son of Balas known as Antiochus Zabinas. (Is he really the son of Balas?
Does anyone care?) Zabinas quickly gains control of the inland region
once held by Tryphon and Syria is again divided. Finally
Demetrius is defeated outside Damascus and retreats to Ptolemais
only to find the gates closed against him by his wife Cleopatra. He takes
a ship and is killed on Cleopatra's orders.
Cleopatra decides to rule in her own right and Selecus's the eldest son
of Demetrius is killed when he is foolish enough to put forward his claim.
As a sop to those unaccustomed to female rule she associates her rule with her son
the pliable Antiochus Grypus (hooknosed). Zabinas is defeated by Grypus.
Antiochus proves to be less and less pliable. Things come to a head
when Cleopatra offers a cup of wine to Antiochus when he has returned
from the hunt. As this is most definitely not her habit Antiochus has
a hunch this is not maternal concern. He insists she drink the wine.
She drinks. She dies.
Bevan's explanation is folly. The Seleucids had the bad luck to be produce a bunch of tyrants who squandered the fine empire they inherited from illustrious ancestors. Peter Green's explanation goes deeper but is essentially the same (though unlike Bevan he regards the Empire as flawed from the start).
"If the 'degenerate' has any meaning at all the later Seleucids and Ptolemids were degenerate:
selfish, greedy, murderous, weak, stupid, vicious,sensual, vengeful....
In both dynasties we also find the cumulative effect
of centuries of ruthless exploitation: a foreign elite, with no
long term economic insight, aiming at little more than the immediate profits
and dynastic self perpetuation, backed (for their own ends)
by shrewd local and foreign businessmen and always able to count
on a mercenary army when resentment reached boiling point."
