Alexander I Theopator Euergetes, surnamed Balas, was the ruler of the Seleucid Empire from 150 BC to August 145 BC. Picked from obscurity and supported by the neighboring Roman-allied Kingdom of Pergamon, Alexander landed in Phoenicia in 152 BC and started a civil war against Seleucid King Demetrius I Soter. Backed by mercenaries and factions of the Seleucid Empire unhappy with the existing government, he defeated Demetrius and took the crown in 150 BC. He married the princess Cleopatra Thea to seal an alliance with the neighboring Ptolemaic kingdom. His reign saw the steady retreat of the Seleucid Empire's eastern border, with important eastern satrapies such as Media being lost to the nascent Parthian Empire. In 147 BC, Demetrius II Nicator, the young son of Demetrius I, began a campaign to overthrow Balas, and civil war resumed. Alexander's ally, Ptolemaic king Ptolemy VI Philometor, moved troops into Coele-Syria to support Alexander, but then switched sides and threw his support behind Demetrius II. At the Battle of the Oenoparus River in Syria, he was defeated by Ptolemy VI and he died shortly afterward.
The 2nd century BC started the first day of 200 BC and ended the last day of 101 BC. It is considered part of the Classical era, although depending on the region being studied, other terms may be more suitable. It is also considered to be the end of the Axial Age. In the context of the Eastern Mediterranean, it is the mid-point of the Hellenistic period.

Year 150 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Flamininus and Balbus. The denomination 150 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
Year 164 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Torquatus and Longinus. The denomination 164 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
Demetrius I, surnamed Soter, reigned as king (basileus) of the Hellenistic Seleucid Empire from November 162 to June 150 BC. Demetrius grew up in Rome as a hostage, but returned to Greek Syria and overthrew his young cousin Antiochus V Eupator and regent Lysias. Demetrius took control during a turbulent time of the Empire, and spent much of his time fighting off revolts and challenges to his power from threats such as Timarchus and Alexander Balas.
Seleucus IV Philopator, ruler of the Hellenistic Seleucid Empire, reigned from 187 BC to 175 BC over a realm consisting of Syria, Mesopotamia, Babylonia and Nearer Iran.
Antiochus IV Epiphanes was a Greek Hellenistic king who ruled the Seleucid Empire from 175 BC until his death in 164 BC. He was a son of King Antiochus III the Great. Originally named Mithradates, he assumed the name Antiochus after he ascended the throne. Notable events during Antiochus's reign include his near-conquest of Ptolemaic Egypt, his persecution of the Jews of Judea and Samaria, and the rebellion of the Jewish Maccabees.
Cleopatra I or Cleopatra Thea, surnamed Eueteria was a ruler of the Hellenistic Seleucid Empire. She was queen consort of Syria from 150 to about 125 BC as the wife of three Syrian kings: Alexander Balas, Demetrius II Nicator, and Antiochus VII Sidetes. She ruled Syria from 125 BC after the death of Demetrius II Nicator, eventually in co-regency with her son Antiochus VIII Grypus until 121 or 120 BC.
Berenice IV Epiphaneia was a Greek princess and Queen of the Ptolemaic dynasty. From 58 to 55 BC, Berenice IV ruled Egypt during the political exile of her father Ptolemy XII Auletes to Rome. It is unclear if she was co-ruler of Egypt with her mother Cleopatra V or a possible sibling Cleopatra VI from 58 to 57 BC, but became sole ruler in 57 BC. On the return of Ptolemy XII to Egypt with Roman military aid and an army led by Aulus Gabinius, Berenice IV was overthrown and executed by her rival father, who later bequeathed his throne to his daughter Cleopatra VII and son Ptolemy XIII as co-rulers.
Cleopatra Selene was the Queen consort of Egypt from 115 to 102 BC, the Queen consort of Syria from 102–92 BC, and the monarch of Syria from 82 to 69 BC. The daughter of Ptolemy VIII Physcon and Cleopatra III of Egypt, Cleopatra Selene was favoured by her mother and became a pawn in Cleopatra III's political manoeuvres. In 115 BC, Cleopatra III forced her son Ptolemy IX to divorce his sister-wife Cleopatra IV, and chose Cleopatra Selene as the new queen consort of Egypt. Tension between the king and his mother grew and ended with his expulsion from Egypt, leaving Cleopatra Selene behind; she probably then married the new king, her other brother Ptolemy X.
The Syrian Wars were a series of six wars between the Seleucid Empire and the Ptolemaic Kingdom of Egypt, successor states to Alexander the Great's empire, during the 3rd and 2nd centuries BC over the region then called Coele-Syria, one of the few avenues into Egypt. These conflicts drained the material and manpower of both parties and led to their eventual destruction and conquest by Rome and Parthia. They are briefly mentioned in the biblical Books of the Maccabees.
The Seleucid Dynastic Wars were a series of wars of succession that were fought between competing branches of the Seleucid royal household for control of the Seleucid Empire. Beginning as a by-product of several succession crises that arose from the reigns of Seleucus IV Philopator and his brother Antiochus IV Epiphanes in the 170s and 160s, the wars typified the final years of the empire and were an important cause of its decline as a major power in the Near East and Hellenistic world. The last war ended with the collapse of the kingdom and its annexation by the Roman Republic in 63 BC.
Antiochus was a Hellenistic monarch of the Seleucid Empire reigning between 175 and 170 BC.
