Status during eras: Old Republic era, Foundation to Separatist Crisis

620 BBY: The Antarian Rangers were founded some 600 years before the Clone War

Organization with just over a thousand total members

Soon after: It soon spread beyond Antar 4 into the rest of the galaxy

Early years: In the early years, the organization was small but ambitious

Upon Timpel's death, Kaskutal relegated himself to a more administrative role

570 BBY: Within 50 years, the Antarian Rangers had divisions in several well-populated systems, including Corellia, Brentaal, Ruan, and Coruscant

Over time: Over time, the expansion throughout the Core Worlds caused the organization to become Human-dominant. Presumably, reaching the status of “multiple sectors organization” at this point in time.

Gradually: There were fewer and fewer Rangers around

As the Clone Wars approached: Some branches disbanded due to inactivity

Some branches used their combat training and entrepreneurial skills to become freelance mercenaries

Some branches became Sector Defence Forces

The organization, reduced to less than half its former size (so less than 500 before the separatist crisis)
