Thrace is a regional power in the Balkans, controlling the coastal south and east of the region of Thrace proper. Founded as a Argead satrapy assigned to Lysimachus after the death of Alexander the Great, Thrace in 450 AUC is the smallest and weakest of the remaining Diadochi states, dealing with a host of unruly subjects and opposing the attempts of the Antigonid Kingdom to destroy Macedon and extend its rule into Europe but facing stiff odds unless Egypt and the Seleukid Empire can be convinced to join the fray. Historically this coalition would emerge victorious in the last major war of the Diadochi, with Thrace given western Anatolia as its share of the former Antigonid lands and extending its rule over the smaller states of the northern coast, eventually extending its rule over Macedon as well after the fall of the Antipatrid dynasty. This success would prove to be short lived, with Thrace falling briefly to the Seleukos himself in 281 BC and then a revived Macedon under the Ptolemaic prince Ptolemy Keraunos before the kingdom's collapse at the hands of the Gauls. The Lysimachid dynasty itself would survive in the Ptolemaic client state of Telmessos for many decades afterwards, while Thrace itself would be divided between Antigonid Macedon, a resurgent Odrysia and Getia, and various independent city-states.

- Main article: Thracian missions
With the Heirs of Alexander DLC, Thrace has a unique set of 3 missions focusing on Lysimachus's tenuous satrapy: consolidating control over his paper kingdom and securing control over the tribes of the north, improving relations with the Greek city-states to pacify the feudatories of the coast and extending Thracian influence over Greece, and bringing the war to other Diadochi through the conquest of Macedon and the Antigonid heartland of Anatolia.
If the A New Philhellenic Policy and Crossing the Hellespont missions are successfully completed, the Diadochi Empire mission becomes available, with a focus on restoring the Hellenistic Empire of Alexander the Great.
With or without DLC, Thrace will also always have access to the generic missions.
The Wars of the Diadochi
- Main article: Diadochi events
At start, all the Diadochi states will receive an event that gives them claims on all of the western half of the former Argead Empire and access to the special Legacy of Alexander wargoal, allowing them to easily declare war and conquer much more territory from each other than would be possible in a normal war. For Thrace, these claims will go away on the death of the first ruler.
Fourth War of the Diadochi
Shortly after the game starts, the Antigonid Kingdom will receive an event to make an ultimatum against Macedon, demanding they retreat from their remaining holdings in Greece. If war breaks out, after a few months Egypt and then the Seleukid Empire may join the fray and demand territorial concessions or go to war; some months after that, Thrace will also receive an event that will let it join the fray and directly declare war on the Antigonids or present an ultimatum to cede the border regions of Asia and Bithynia in exchange for a truce. All of these wars use the Legacy of Alexander wargoal, which drastically increases the stakes of winning or losing the war.
The Antigonid Cause Wavers
- Main article: The Antigonid Cause Wavers
When Antigonos I Monophthalmos, the starting ruler of the Antigonid Kingdom, dies, their empire will disintegrate if they have not managed to conquer Korinthos (418) from Macedon or have failed to maintained control over a number of key cities scattered across their vast Asian territories. Any ongoing wars against the other Diadochi will end and governors and subjects across the Antigonid realm will begin to defect from the Antigonid cause, forcing the Antigonids to choose between retreating from Asia and maintaining control over their coastal subjects and possessions with their powerful fleet, or abandoning their pretensions to the west to save the Asian core of the kingdom.
Once the event triggers, Thrace (if it still exists) will seize control over Antigonid territories in Bithynia and northern Asia, as well as gaining Sardis (or rarely Pergamon) as a satrapy over the rest of Asia. If the Antigonids decide free to Greece and abandon Asia as historically, Thrace will additionally gain Phrygia as a satrapy controlling most of the former Antigonid Phrygia. Depending on which choice is made, the other Diadochi will take over similarly large portions of their former empire as well.
Amastris marriage events
A few years into the game, Lysimachus will receive an event allowing him to propose his historical marriage to Amastris, the queen of Heraclea Pontica. He can then choose to extend the offer, which if accepted will have Amastris will leave Heraclea Pontica to her heir and join Lysimachus in Thrace who will extend a guarantee to her old kingdom, or get claims on the area to extend Thrace's influence more aggressively.
If Pergamon is released from the Antigonid Kingdom as the result of the The Antigonid Cause Wavers event and Lysimachus is still alive, Thrace will get an event to either offer tributary status to the newly released country or get claims on the bordering provinces, representing Thrace's historical expansion into the area. Pergamon can also be released as a client state if Thrace manages to conquer much of Asia from Antigonid Kingdom.
If the Heirs of Alexander DLC is not enabled, in the early part of the game Thrace will get an event allowing it to choose how to deal with Odrysia, with choices including declaring war to directly annex it, seizing several neighbouring territories, and forcibly converting it into a client state. This is useful as Odrysia beings as a tribal vassal, which cannot be integrated or annexed without breaking the subject relationship altogether.
With the Heirs of Alexander DLC, Odrysia will instead get periodic events to revolt if Thrace is distracted in another war, with special opportunities to offer peace and return to status quo if the war is not going well. As long as Odrysia remains a subject of Thrace, however, it well continue to get opportunities for these revolts until Thrace manages to appease or decisively defeat the Odrysians through the tasks of the unique Thracian mission tree The Paper Kingdom.
Pontic revolt events
- Main article: A New Philhellenic Policy mission events
If the Heirs of Alexander DLC is enabled, the other Diadochi will get events to sponsor revolts among Thrace's feudatory subjects on the coast of the Pontic sea if they are at war. Up to three of the city states may be contacted, and if they accept they will band together to declare a war of independence against Thrace, reflecting the historical revolt of the Pontic Pentapolis during the early part of Lysimachus's reign. This can happen up to once every 7 years, unless the cities are appeased or annexed through Thrace's unique A New Philhellenic Policy mission tree.
- Main article: Macedonian events
A few years into the game, Kassandros of Macedon and then his heir Philippos IV will fall significantly ill, forcing a succession crisis once the basileus and the primary heir die that may ensue in civil war. If civil war does break out and the Antigonids had previously fled to Greece, the Antigonids will be approached by the leader of the Macedonian Revolt for assistance, which can result in an alliance or a betrayal with the Antigonids annexing all of the claimant's lands. If this happens, the other claimant may either declare war or turn to Thrace for assistance, who will be given a similar choice of either intervening against the Antigonid Kingdom or betraying the other claimant and annexing their lands in turn.
As a Hellenistic culture group monarchy, Thrace has access to the decision to reform the Hellenistic Empire.
Reunite Alexander's Empire
That one power could not possibly come from any dynasty but our own. Only a family that respects the Argead traditions can legitimately claim its legacy.
Thrace starts with the following pantheon:
- War: Heracles
- Economy: Derzelas
- Culture: Zeus
- Fertility: Dionysus
Thrace has a population of 236 spread over its 26 territories, Propontic Hellenic pops along the southern coast making up around half of the population with a smaller proportion of Macedonian Hellenic pops scattered there as well. The less settled northern and inland provinces are instead predominantly Odrysian and Getian (in the Dacian culture group), split between Hellenic and Zalmoxian and comprising some 40% of the population. While Odrysian is an unintegrated culture at the beginning of the game, it can be rapidly integrated in 90 days by completing the Land of the Thracians task in the unique Thracian mission tree The Paper Kingdom if Heirs of Alexander is enabled.
The population type breakdown is listed below:
