Seleukos was born in northern Macedonia in about 358 BC. He was the son of Antiochus, one of Philip II’s generals and a member of a noble family. His mother’s name was Laodice. Curing his later conquests, Seleukos named a number of cities after his parents.Фауна Земли
As a teenager he served as the king’s page. As was the custom, all male offspring of noble families first served in this position and later became officers in the king’s army. He accompanied Alexander’s army to Asia in the spring of 334 BC when he was about twenty-three and within three years he had risen to the command of the elite infantry corps, the “Shield-bearers” (Hypapistai) also known as “the Silvershields”.
In India he led his troops against the warrior elephants of Rajah Porus and was later put in charge of the herd.
At the wedding ceremony of Susa, arranged by Alexander to encourage his officers to marry Persian women, Seleukos married the princess Apama who he had taken to India as his mistress. She later gav birth to his eldest son and successor Antiochus 1 Soter (325 BC) She later bore him at least two daughters and another son. After Alexander’s death, when the other officers deserted their new Susa wives, Seleukos was one of the few who kept his and Apama remained by his side for the rest of his life.
After Alexander’s death, Seleukos was appointed Satrap of Babylon under the Regent, Antipater. Almost at once, though the wars between the Diodochi began and he was forced to flee from Babylon and wasn’t able to return until 312 BC with the help of Ptolemy. From then on he began to ruthlessly expand his dominions until he had conquered Persia and Media, making him ruler of the largest part of Alexander’s empire. He founded a number of cities including Antioch (300 BC) and Seleucia on the Tigris (305BC) which became the new capital of the Seleucid Empire.
By 306 BC, when the struggle between the Diadochi had reached its climax after the extinction of the royal line of Macedonia, Seleukos proclaimed himself king. He now held the whole of Alexander’s conquests except Egypt and was planning to take possession of Macedonia and Thrace as well. He would have likely tried to conquer Greece too, and had already prepared this campaign and had been nominated an honorary citizen of Athens. However, he was assassinated by Ptolemy Keraunos (one of Ptolemy’s sons) in September 281 BC.
