The Ages of Doubt were marked in Covenant rituals with Faith and Patience, and were eras in Covenant history where the effects of the previous eras were dealt with. The last Age of Doubt, the Twenty-third, succeeded the Thirty-ninth Age of Conflict, when the Unggoy Rebellion destabilized the Covenant, and lasted until the discovery of the Reclaimers, Humanity, and the deposition and replacement of the Hierarchs. This age was succeeded by the Ninth Age of Reclamation in 2525.

- Ages of Doubt appear to begin after a time of trouble, for example, the Unggoy Rebellion.
- In Halo Wars, when playing as the Covenant, players can upgrade their temple by researching the Age of Doubt, improving all Covenant technology by 1. Advancing to the Age of Doubt also gives Covenant players the ability to make Locusts, Vampires, and many other types of units.
