In an alternate timeline known as the Protectorate's timeline, the Vulcan Protectorate was an interstellar state controlled by the Vulcans. In this reality, Humans died out in the 1950s decade (see Miri's World), hence there was no Jonathan Archer to help the Vulcans rediscover the Kir'Shara and they became a militaristic and dogmatic culture.

History and specifics
In the 22nd century, the militaristic administrator of the Vulcan High Command, V'Las, collaborated with the Romulans to instigate war with the Andorians. After Ambassador Soval's assassination on Paan Mokar the peace talks with the Andorians failed. The Vulcan Muroc subsequently led a guerilla war against them and drove the occupiers off. He was appointed fleet commander in the invasion of Andor. Andor was conquered and a puppet government installed.
At the same time, the Vulcans infiltrated the Romulans and assimilated them into their society.
The Vulcan Protectorate was a rival of the Klingon-Andorian Compact, an alliance formed to counter Vulcan influence in local space. Technologically, both states were behind the Federation due to the lack of multispecies cooperation.
By 2274 the Vulcan Protectorate also controlled Coridan III and Paan Mokar and had acquired Vedala technology. In that year, the VHC Muroc accidentally traded its place with the Federation starship USS Enterprise from the primary universe due to the Vedalan technology. The Vulcans were hostile to the Federation starship, which sought refuge in the uninhabited Sol system before making overtures to the Klingon-Andorian Compact.
Following a battle between the Protectorate and the KAC over the Enterprise and the Vedala technology, the Federation starship and the Muroc were able to return to their respective universes.
While in the prime universe, Commander Spock had introduced Subcommander T'Pring to the original teachings of Surak encoded in the Kir'Shara artefact. The Kir'Shara had been recovered by the Human Jonathan Archer in the 22nd century, whereas their Syrrannite guardians were bombed into extinction by V'Las in the Protectorate's timeline.
In 2275, the appearance of the Timeship Two threatened the barrier between the Protectorate's timeline and the prime universe. Commander T'Pring and her ship from the year 2383 intervened when the Compact warship Thorn of Justice attacked the USS Enterprise. T'Pring worked with Captain Spock and other parties to repair the temporal damage.
Following the recovery of the Kir'Shara, the Vulcans found peace within themselves and with other peoples, truly reforming the Romulans as well. Andor was given independence and a detente was reached with the KAC around 2293, after the Klingons had to accept the Vulcans' aid during a crisis
Following the peace between the Protectorate and the KAC, an extremist group of KAC terrorists retained their hostile stance against the Vulcans. Due to interspecies cooperation, the Protectorate outpaced these extremists technologically and were able contain them except for isolated acts of terrorism. (DTI novel: Forgotten History)
In 2279, Captain Spock of the Enterprise reminisced about the visit to the Protectorate's timeline during a mission to the extradimensional realms of the Medusan Complex. In a conversation with Petty Officer Reiko Onami, they referred to the Vulcan state as the Vulcan Consortium. (TOS novel: The Higher Frontier)
By 2383, T'Pring had attained the rank of commander and served as commanding officer of a starship that was based on, but more advanced than, the Suurok-class of the Confederacy of Vulcan. (DTI novel: Forgotten History)
