The Recusal was the Jedi Order's response to the Pius Dea Crusades. In 11,933 BBY, the Order decided that they could no longer associate themselves with the Pius Dea-controlled Galactic Republic, and that their actions against alien species were immoral.
The Order decided to extract itself from the Republic and severed all ties, retreating to their academy world of Ossus. The Jedi would remain there for the next eight centuries, until the Caamasi convinced them to act against the Republic. Although the Order itself remained on Ossus, some Jedi acted on their own against the Pius Dea, and some misguided Jedi even joined the Pius Dea. These Jedi settled on Garn, and went on to form the Order of the Terrible Glare.
