As we all know, it is possible for a species to have more than one state or nation; at the present time humans have about two hundred, and they once had many thousands.
And if the different species in Star
Star Trek are considered more or less like ethnic groups on Earth, we know that there are many historical examples of an ethnic group having more than one state or nation - in fact Koreans have two at the present time.
And there are 22 nations whose populations are Arab enough to be part of the Arab League.
There were tens or hundreds of independent ancient Greek city states as a historical example.
In South Africa the Boer or Afrikaner ethnic group was famous for having many short-lived states and nations. There is a list of about 18 of them here:

And sometimes there were up to four or five at a time if I remember correctly. The South African Republic or Transvaal lasted from 1852-1877, 1881-1902, and 1915-1916, while the Orange Free State lasted from 1854 to 1902.
And there have been times when there were four, five, six, or even seven, more or less "Roman", Roman empires at the same time.
It is my theory that over the centuries many splinter groups of Kingons have broken away from the original Klingon state, especially in the confused times after
Star Trek VI: The Undiscovered Country. Many have united with or been conquered by other Klingon states or by non Klingon states, but a number still remain independent.
One such splinter group may be the klingon realm from "Heart of Glory" which seems to have very close ties to the Federation and may have a capital planet named Kling.
Another may be the successor to the Kligon realm in
Star Trek VI: The Undiscovered Country and is inhabited by Worf's group of Klingons. Picard specified the capital planet of the realm in "Sins of the Father" when he said to set course for the capital of "the Klingon Imperial Empire", using the full name so as not the confuse it with any other Klingon Empires.
