Narendra III
Narendra III was the inhabited third planet in the Narendra system of the Beta Quadrant. This planet was colonized by the Klingons prior to 2152. ()

In that year, the Human Captain Jonathan Archer was put on trial on Narendra III, under the suspicion of conspiring against the Klingon Empire. Archer was sentenced to lifelong exile on Rura Penthe, and his advocate  had to join him for one year. However, Archer was later rescued from Rura Penthe by his crew. ()

In 2344, the outpost was attacked and destroyed by four Romulan warbirds, an assault which was later known as the Battle of Narendra III. The outpost's distress call was answered by the Federation starship , and although outnumbered four-to-one engaged the Romulans, only to be destroyed during the battle. This course of action was considered as an act of honor by the Klingon Empire, which led to the signing of a new peace treaty.

In an alternate timeline, the Enterprise-C disappeared during the battle. The outpost was destroyed, and events led to a renewed  between the Federation and the Empire. ()

Background information 
This planet's quadrant of origin is inferred based on the position of its star system as seen in the star charts appearing in the  episode  and in the  episode .

According to Eric A. Stillwell, this planet was named after  writer and science consultant Naren Shankar. (The Making of Yesterday's Enterprise, p. 77) "nah-REN-druh" was how the planet's name was phonetically spelled in the script pronunciation guide for "Yesterday's Enterprise". 

Although the planet shown in "Judgment" is never identified as Narendra III on screen (the term "Narendra" is not mentioned there at all), the episode's final draft script referred to it as such.  Also, David A. Goodman, the episode's writer, stated in a podcast that he intended for the settlement/installation shown to refer to the outpost from "Yesterday's Enterprise".

In the final draft script of "Judgment", an overview of an area on Narendra III shown in that installment was described as "A large city on this Klingon outpost, with familiar Klingon-style architecture. In the center of town, a GRAND TRIBUNAL BUILDING which proudly displays the three-pointed Klingon symbol."
