The kingdom of Syria was not confined to that country alone, but also comprehended those vast and fertile provinces of upper Asia, which formed the Persian empire; being, in its full extent, bounded by the Mediterranean on one side, and the river Indus on the other. These wide-spreading dominions are commonly called the kingdom of Syria, because Seleucus, the first of the Syro-Macedonian kings, having built the city of Antioch in that province, chose it, as did likewise his successors, for the usual place of his residence. Here his descendants, from him styled Seleucidæ, reigned, according to Eusebius, for the space of 251 years, that is, from the 117th Olympiad, when Seleucus recovered Babylon, to the third year of the 180th, when Antiochus Asiaticus, the last of the race of Seleucus, was driven out by Pompey, and Syria reduced to a Roman province. Before we proceed to the history of the Seleucidæ, we shall exhibit a series of the kings of that race, with the years of their respective reigns.

Seleucus, the founder of the Syro-Macedonian empire, was the son of Antiochus, one of the chief captains of Philip, the father of Alexander. He served under Alexander from his tender years, attended him in his expedition into Asia, and was by him honoured with the chief command of the elephants, a commission of great trust and reputation. After the death of that conqueror, Perdiccas, whom the officers had unanimously appointed regent of the empire, placed Seleucus at the head of the cavalry of the allies; in which command he acquitted himself with such reputation that Antipater, who succeeded Perdiccas in his regency, raised him to the government of Babylon and its territory.
SELEUCUS
In this post he was tempted, by the example of the other captains of Alexander, who aspired to the supreme power in their respective allotments, to betray his trust, and entertain thoughts of setting up for himself; whence, when Eumenes, on his march into Susiana, pressed him to join the governors of the upper provinces against Antigonus, who had openly revolted, he not only refused to lend them any assistance, but even attempted to destroy both Eumenes and his army, by cutting the sluices of the Euphrates, and laying the whole plain where they were encamped under water. Eumenes, however, though thus surprised, reached an eminence with his troops, before the waters rose to any height, and the next day, by diverting their course, found means to escape the danger, without the loss of a single man. Seleucus made a truce with Eumenes, granting him a free passage through his province. But when Antigonus demanded an account of the revenues of his government, the answer he gave him so exasperated Antigonus that he thought it advisable to abandon his province, and put himself under the protection of Ptolemy, governor of Egypt.
[312-300 B.C.]
Seleucus meeting with a friendly reception from Ptolemy, in Egypt, represented so effectually to that prince, as also to Lysimachus and Cassander, the formidable power and ambitious views of Antigonus, that he engaged them all three in a league against him. This war put an end both to the life and reign of Antigonus. After the victory which Ptolemy gained over Demetrius at Gaza, Seleucus, having obtained of the conqueror a thousand foot and two hundred horse, took his route towards Babylon, in order to attempt the recovery of that city. This undertaking was looked upon as a desperate enterprise, even by his friends, but was attended with all the success he wished for.
