Portian colonial period

The Portian colonial period was an era of Terran salticid history beginning in about 700 PT with the gradual expansion of Portia into Vast Mopsus and the oppression and disenfranchisement of the central Mopsus salticid population.

History
Portia had long established itself as xenophobic and ethnocentric, being the first salticid species to split off from the Terran Mingle. Its war with Hyllus and the subsequent Burning of Hyllus set the Portians apart as willing to use ultraviolent technologies to conduct campaigns of mass murder and genocide against other salticids.

Portia began practicing silk slavery against the Vast Mopsus population around 700 PT, capturing some small canopies and testing the new technology on their inhabitants. In 722 PT the state began its incursion into Vast Mopsus in earnest, wiping out whole local governments and enslaving their constituents.

In 730 PT, Helpis declared war against Portia, setting off a decade-long losing battle during which Helpis was colonized and forced to surrender. The establishment of a largely Portia-controlled Helpis state in 739 PT marked the beginning of Portia's near-ubiquitous presence in and totalitarian rule over the Terran continent.
