The D'jarras were a Bajoran caste system, once used by the Bajorans to create a stratified social hierarchy in the Bajoran year 9100s. Everyone was born into a specific caste of D'jarras based on their family, which determined their occupation. Higher-ranking D'jarras were treated with respect and deference by those of lower ranks. For example, the Ih'valla are a caste of artists and sculptors, and were ranked higher than the Te'nari. In some cases, Bajoran family names indicated the D'jarra to which family members belonged; for example, the family name Kira indicated membership in the Ih'valla, or artists' D'jarra.
The D'jarra system was set aside during the Cardassian Occupation of Bajor, so that all Bajorans could fight as soldiers to liberate their homeworld. After the Cardassian withdrawal, the status quo was maintained, as too many people were now performing jobs far different from their D'jarras, and only the most conservative of Bajorans paid the matter any thought.
In 2372, Akorem Laan called for the restoration of the D'jarra system after he assumed the position of Emissary of the Prophets, believing that the Bajorans had strayed from the path the Prophets set for them by abandoning the D'jarras. In spite of Kai Winn's support on the issue, resumption of the D'jarras was a deeply divisive issue amongst the Bajorans, many of whom refused to return to their castes. Akorem hoped that eventually the D'jarras would be enforced by legal measures, such as deportation.
For the Federation, the D'jarras were also a source of great concern since caste-based discrimination would disqualify Bajor for Federation membership. When a vedek from the family Imutta was murdered by Vedek Porta for refusing to resign, because his D'jarra involved preparing the dead for burial and was therefore unclean, Captain Benjamin Sisko challenged Akorem's claim as the Emissary. After the Prophets confirmed that Sisko was the true Emissary and returned Akorem to his own time, the idea of returning to the D'jarra system was quickly abandoned. (DS9: "Accession")
Individuals with known D'jarrasEdit
- Kira Nerys would have been a member of the Ih'valla, or artists' D'jarra.
- Shakaar Edon would have been a member of the farmers' D'jarra. Akorem Laan and Vedek Porta hoped that if the D'jarra system were restored, Bajorans would not elect a member of this D'jarra to political office.
- Gia was a member of the Te'nari D'jarra. They ranked lower than the artist D'jarra Ih'valla.
- Vedek Imutta was a member of a D'jarra whose role was to prepare the dead for burial. Under the D'jarra system, members of this caste were considered unclean.
According to the script, d'jarra was pronounced as "duh-ZHAR-uh". 
The D'jarras of some Bajoran characters seen or mentioned in the episode "Accession" can be deduced from known cases. For example, other members of Kira Nerys' family, such as her brothers Kira Pohl and Kira Reon, would also have been Ih'valla.
- Mi'tino - low ranking merchants and land owners
- Va'telo - pilots, sailors and similar professions
- Ke'lora - laborers and lawmen
- Sern'apa - unspecified, possible the priests.
Imutta is listed as the "unclean" caste that deals with the dead. In "Accession", Imutta was only given as the family name of a person of this caste.
The Terok Nor novel Night of the Wolves states that then-Vedek Opaka advocated for the D'jarras' abolition in the late 2340s, as the Cardassians were using the caste system to play the Bajorans off against each other. She was expelled from the Vedek Assembly over it by Kai Arin.
