The Freeholders are a Martian based political and paramilitary organisation with origins in the anarchic terrorist Kasei Freeholder society. Their current leader is Augustine Okafor.

The Kasei Freeholders were a community descended from a partially abandoned Dominio settlement attempt in the labyrinthine canyon system of Kasei Valles. They developed a fiercely independent and terranophobic culture, supporting themselves by selling bio-hacking, smuggling, and similar black market activities. In the political vacuum that developed in the early years of the Retrograde Diaspora the Kasei Freeholders began to sponsor content on MarsNet supporting Martian culture and agitating against the large corporations which were effectively running most of the colonies, all of which were primarily Earth based. They sponsored mutual aid societies and likely worked with Dominio and Greater Zhōngguó to exploit class differences and dislike of the United States in areas which were profitable for US corporations.

In response to the Stillborn Harvest incident the Peacekeepers destroyed most of the Kasei Freeholder's above ground infrastructure, resulting in the loss of most of their revenue sources. By the mid 30s their outposts were abandoned and they had split into a political wing and an underground paramilitary group.

Their political wing currently has active branches in all of the larger colonies, and advocates for an anti-corporate, pan-Martian identity. They have had success in seeking financial support and public representatives from Earth such as Nimitra Wongprasert. The paramilitary arm operates black market activities and directs funds towards strikes, protests, skirmishes, and terrorist activities, the most notable of which was the hijacking of a quantity of antimatter which they still claim to posses and have threatened to use on a number of occasions. The paramilitary arm sometimes work together openly with the political organisation, most recently in organising and participating in the Nanocat Fury protests.
