The Seleukid Empire is a Major Power in the Middle East and one of the main Diadochi kingdoms that has emerged from the fall of the 
阿吉德帝國, centered in Mesopotamia and controlling all of the eastern Satrapies all the way to Bactria and Arachosia, encompassing about half of the former Argead Empire. With 3172 pops spread over 383 territories and a number of subject nations, including three large satrapies to the east, it is one of the wealthiest, most populous, and most powerful countries in the game, though one whose population is almost entirely of a different culture group and religion from the Macedonian ruling class. With the 
弗里吉亞 vulnerable and likely to end up at war with all of the other Diadochi soon after game start, the Seleukids are well positioned to destroy their Antigonid rivals and claim the rich territories of the west - though only if they can keep the rising 
Mauryans, restless populace, and Scythian tribes at bay. Historically the Seleukids would conquer much of Syria and Anatolia after the fall of the Antigonids and 
色雷斯 to control nearly all of the Asian part of the 阿吉德帝國, but would be weakened by devastating civil wars and see most of their territory lost to 請檢查模板名和國家代碼：{{Countries|flag/core|Parthia (Formable)}} Parthia and

Name
As a dynamically named country, the name of the Seleukid Empire can and usually will change at some point during the game. If the ruling dynasty changes or the country is no longer a monarchy, the former Seleukid Empire will receive an event to break with its dynastic traditions and naming, allowing the country to choose between renaming itself the Persian Empire if its capital is in Greater Persia (Persis, Media, Mesopotamia, or Ariana) or taking a more general name based on its capital region (e.g. Syrian Empire, Mesopotamian Empire, Assyrian Empire, etc.).
Apart from that event, the base name of the country will always use the name of the ruler's family and takes the form [RulerDynastyAdjective] Empire, defaulting to Persian Empire as a fallback if the country ceases to exist or has no ruler for whatever reason. This behaviour is also currently active if the country loses a 
civil war.
Events
The Wars of the Diadochi
At start, all the Diadochi states will receive an event that gives them claims on all of the western half of the former 阿吉德帝國 and the special Legacy of Alexander wargoal, allowing them to easily declare war and conquer territory from each other. For the Seleukid Empire, these claims will go away on the death of the first ruler.
Fourth War of the Diadochi
Shortly after the game starts, the 弗里吉亞 will receive an event to make an ultimatum against 
馬其頓, demanding they retreat from their remaining holdings in Greece. If war breaks out, after a few months 
埃及 may join the fray and demand territorial concessions or go to war; afterwards the Seleukid Empire will also receive an event that will let them directly declare war on the Antigonids or present an ultimatum to cede most of Syria, including their capital of Antigoneia, in exchange for peace. 色雷斯 will also receive a similar event to make demands or enter the war a few months afterwards.
The Seleukid-Mauryan War
At the beginning of the game, the Seleukids must also decide how to resolve the ongoing war with 孔雀, which has recently expanded into the former Indian satrapies of the 阿吉德帝國. The Seleukids can choose to either sue for peace and cede control over some of their eastern provinces as well as the satrapy of 
阿拉科西亞 for an extended truce, some war elephant units, and a bonus to 
siege ability in order to focus on the west, or press onwards and get claims on the neighboring Indian regions (Gandhara and Maru), which will lead to renewed war in the west.
Parthian hordes
After the unification of the Dahaean hordes sometime after 480 AUC, the Dahaean leader will receive an event to launch a raid on a Seleukid border patrol led by the Basileus himself. If they choose to go ahead, they will immediately declare war and kill the Seleukid leader, giving the Seleukids a significant malus to 
unintegrated culture group happiness and 
character loyalty to compound the instability from succession, which may quickly lead to civil war amidst the invasion.
Decisions
The 
塞琉古帝國 has two country-specific decisions around moving the capital to the city of Antiocheia (the former Antigoneia, capital of the 弗里吉亞 at start) and improving its nearby port of Seleukia Pieria. The decisions can be found in /ImperatorRome/decisions/seleucids.txt.

For too long the rightful heirs of Alexander's empire have been disconnected from the Macedonian heartland which bore the greatest conquest of history and all the fortunes of our people. Fertile Babylonia has served us well, but we must restore our ties with the lost lands to the west and establish a central point of governance on the Mediterranean if we are to succeed in re-claiming the lands of Megas Alexandros.

As one of the easternmost Hellenistic states, the Seleukid Empire can take the decision to move their centre of power to Northern India and embrace greater cultural syncretism if they make conquests in the region, representing the historical creation of the Indo-Greek kingdoms.
Finally, as a Hellenistic culture group monarchy, the Seleukid Empire also has access to the decision to form the 阿吉德帝國.

Combined with the modifiers from Seleukid Empire's unique heritage (which gives among other things +6% Unintegrated Culture Group Happiness), if the Seleukid Empire manages to take both of these decisions it can accumulate one of the highest unintegrated culture group happiness modifiers in the game, making dealing with foreign conquests and 
aggressive expansion much easier.
Government
The Seleukid Empire starts off as an Aristocratic Monarchy that is ruled by Basileus Seleukos Nikator Seleukid (13 Martial/14 Finesse/8 Charisma/6 Zeal), of the Seleukid family.
Diplomacy
The Seleucid Empire has no allies, but six subjects, in 450 AUC. As long as they remain loyal they will provide a significant amount of military support, particularly with any wars in the east.
Additionally, the Seleukid Empire borders the Diadochi kingdom of the 弗里吉亞 to the west (along with its subjects of 
孔馬革涅 and 
卡帕多基亞), 
亞美尼亞 and 
阿特羅帕忒涅 to the north, 孔雀 to the east, and 
革耳剌 and 
馬卡 to the south.
Population
The Seleukid Empire has 
3172 Population at the beginning of the game, divided across 
383 territories. Most of the Iranian plateau is Zoroastrian and in the Iranian culture group, comprising the majority of the Seleukid population at start (about 656%). Pops in the Aramaic culture group, split between Assyrians in the north and Babylonians in the south, dominate in Mesopotamia and largely follow the Chaldean religion, making up some 26% of the population and most of the capital region population. Only about 12% of the population follows the state culture and religion, with Macedonian Hellenic pops concentrated in the some of the major cities and recently founded Alexandrian colonies. Smaller negligible minorities of Qedarite Arabic and Hebrew Jewish pops also exist scattered throughout Mesopotamia, as well as Armenians and Cappadocians along the northern borders.
Population Types:
36 Nobles (1.13%)
541 Citizens (17.06%)
910 Freemen (28.69%)
736 Tribesmen (23.20%)
948 Slaves (29.89%)

At the beginning of the game, there is a decision for the Seleukid Empire: if they want to wage war against 孔雀, or give them the eastern part of the empire for ten years of peace and five cohorts of war elephants. There is the possibility to go into war with 孔雀 and offer them peace immediately by giving up the subjects 
巴克特里亞 and 
堤洛斯. But it is recommended to give them the land and take the elephants like Seleukos did historically. Firstly, a war against 孔雀 is very difficult in the Seleukid Empire's situation in 450 A.U.C., as all your troops are at the other side of your country and the Mauryans have a much stronger army and economy at the start. Secondly, 巴克特里亞 as a Subject will become very important, primarily due to the tribute they pay to you each month. Later in the game, you will not have too much trouble with 孔雀, but especially in the beginning, they might be a problem. Thirdly, you can concentrate on gaining territory in the west, which is much easier and much more valuable at the start. You can occupy land in the 弗里吉亞 pretty easily, as they are usually at war with all of the other Diadochi some years after the start. If you win against them, you can gain territory with Hellenic population, which affects the stability of your country in a positive way. The majority of your population at the start do not share the same culture and religion as your leader, and especially after you rack up some aggressive expansion, you have to be careful not to let a civil war break out.
