Around 13,720 BBY in later chronological reconstructions, the ancient Herglic Trade Empire collapsed. The empire had grown from the aquatic world Giju and had once connected dozens of systems through trade, colonization, and unusually sophisticated technology. Yet the exact year of its collapse was never directly supplied by the principal source. The date comes from working backward from later contact with Human colonists in the Tapani region. IDS therefore includes the event because the collapse itself is important, while marking the numerical date as reconstructed.
An empire built around trade
The Herglics were native to Giju, an oceanic world in the Colonies. They developed hyperdrive in remote antiquity and established settlements across nearby systems. Unlike an empire remembered mainly through conquest, the Herglic state was defined by trade routes, shipping, production, and commercial contact.
Its surviving geographic legacy became known as Herglic Space. Giju remained the cultural center, while later routes such as the Hidakai Pool, Giju Run, Herglic Alley, and Rimma Trade Route crossed or touched the same region.
Technology that later generations could not reproduce
Archaeological evidence attributed exceptionally advanced machines to the early Herglic empire. Some ruins contained devices that later investigators believed manipulated gravity for purposes they could not understand. Legends sources even suggest that aspects of the technology were not matched during the Galactic Civil War era.
The evidence is fragmentary. It does not justify treating the Herglics as omnipotent or assigning every unexplained ruin to them. It does establish that later Herglic civilization remembered a technologically impressive deep past.
Why 13,720 BBY is uncertain
The familiar date is not presented as an exact timestamp in the underlying historical account. It is derived from a statement that the old empire collapsed approximately one millennium before contact with Human colonists in the nearby Tapani region.
Because the Tapani first-colonist date is itself conventionally placed at 12,720 BBY, later chronologists produced 13,720 BBY for the earlier collapse. IDS preserves that sequence while making the arithmetic visible.
What does “collapse” mean?
The surviving sources do not describe a single capital falling, a final battle, a dynasty being overthrown, or a natural catastrophe destroying Giju. “Collapse” may have meant political fragmentation, economic contraction, loss of long-range control, technological decline, or several of those processes together.
The lack of a dramatic ending matters. Large political systems often disappear through cumulative institutional failure rather than one decisive event.
Records were lost
Much of the early Herglic historical record disappeared with the old imperial structure. That loss explains why later information about the empire is archaeological and retrospective rather than a continuous political chronicle.
Historical silence after collapse does not mean the Herglic people vanished. It means the institutions that preserved and coordinated records no longer functioned in the same way.
Herglic society survives the empire
Giju, Herglic communities, trade practices, and Herglese language survived. This is the central distinction between political collapse and cultural extinction. A state can disappear while the people who created it continue to live, trade, remember, and reorganize.
Later Herglic merchants again became common throughout the galaxy. Their commercial reputation therefore outlived the ancient empire that first spread Herglic influence across the region.
Collapse during the Fourth Alsakan Conflict
The conventional date places the Herglic collapse during the Fourth Alsakan Conflict, which had begun around 13,800 BBY. No source says the Coruscant-Alsakan war caused the Herglic collapse. The events were contemporaneous, not necessarily causally connected.
This overlap is useful because it reminds us that several political systems were changing at once. Galactic history was never a single sequence centered only on Coruscant.
Later entry into the Republic
Later Legends references place the Herglic Trade Empire's incorporation into the Galactic Republic around 13,000 BBY. By then, whatever survived of the earlier empire was entering a larger political order.
The Hidakai Pool began to develop after Herglic integration, and Herglic and Givin navigators later contributed to the route network that eventually connected with the Rimma Trade Route.
Empire, species, and region are not the same thing
The Herglic Trade Empire was a political institution. Herglics were a species and cultural population. Herglic Space was a geographic and historical region. Treating these as interchangeable would make political collapse look like demographic disappearance.
Instead, the later history of Giju shows substantial continuity after the old empire ended.
Anthropological assessment
The Herglic collapse shows why political history should distinguish institutions from populations. The imperial structure disappeared, records were lost, and advanced technology became archaeological evidence, yet Herglic culture remained durable enough to re-enter wider galactic trade.
It also illustrates how chronology can become more precise than its sources. “A millennium before contact” is a broad relative statement. Turning it into 13,720 BBY is useful for ordering events, but the apparent precision belongs to later reconstruction, not the original historical claim.

Collapse of an empire is not the extinction of a society
The long-lived Herglic civilization of Giju survived the loss of its early trading empire. Those are two different historical claims: an imperial commercial network can collapse while the species and its homeworld retain institutions, technology and cultural memory. Later records of Herglic Republic membership should not be mistaken for the precise date that the first empire fell.
The familiar 13,720 BBY placement is explicitly a reconstruction. Lords of the Expanse places the downfall roughly a millennium before the Human colonists' encounter with Herglics in the future Tapani sector. Counting backward from the later 12,720 BBY colonial benchmark produces the approximate date, but that calculation is not evidence of a contemporary Herglic chronicle dated to the same year.
The event illustrates how trade routes, shipbuilding expertise and state institutions can change on different timescales. Later Herglic involvement with Republic commerce did not simply restore an unchanged ancient empire. Historians should distinguish an early imperial collapse, a different later political accession, and continuing cultural life on Giju instead of combining them into one invented cataclysm.
Test the evidence: Does the inferred date 13,720 BBY come directly from a Herglic record of the empire's destruction?
Explanation: No. It is derived by counting backward from a later contact benchmark; the original source does not supply an exact collapse year.
