Essentially, the Inquisitors were former Jedi or Padawans who survived Order 66, but were then turned to the dark side by the Sith. Later, the Inquisitors were a major threat on the Disney+ Star Wars series Obi-Wan Kenobi, and another on the current Star Wars: Ahsoka.
The Inquisitors were killed off in Star Wars Rebels to align with Tarkin's comments about Force usage being a bygone era in A New Hope. The presence of Marrok, a surviving Inquisitor in Ahsoka, adds confusion to the Imperial structure and raises questions about why the character still carries the Inquisitor title.
Storywise, the majority of the Inquisitors died before the events of the original trilogy, with the final Inquisitors dying at the hands of the Ghost team in Rebels. The Grand Inquisitor died at the end of the first season of Rebels during a duel with Kanan Jarrus, and never received a replacement.
Both the Fifth Brother and Seventh Sister were killed by Maul on Malachor while the Eighth Brother fell to his death from atop of the Malachor Sith Temple. The Sixth Brother perished over a decade previously as a result of a confrontation with Ahsoka Tano.

Who was the weakest Inquisitor?
Reva took a lightsaber blade to the middle twice and survived. Writing aside, she has far more determination and will to live than any of the Inquisitors I just mentioned. And she's still weaker than any named Jedi or Sith.
Known survivors. It was said that fewer than one hundred Jedi—approximately one percent of the entire Order—survived Order 66. However, the number seemed closer to two hundred.
They are former Jedi!" During their first years of service, the Inquisitors were weak in the dark side of the Force, for their fighting style was reminiscent of their Jedi training. In order to rectify this, Darth Vader trained them to change their fighting style from a defensive style to an offensive one.
In addition to being the Inquisitorius' headquarters, Fortress Inquisitorius was also where Jedi were taken to be corrupted by the dark side and formed into Inquisitors. If the torture tactics to corrupt them were not successful, they were killed.
Over time, the existence of Inquisitorius and its members became a source of disdain and frustration for other branches of the Empire. Some Imperial officers disliked the interference of Inquisitors, such as Admiral Kassius Konstantine who had no tolerance for assumed conjurers and mystics.
But they are nowhere to be seen by the time of the original trilogy. An easy explanation is that many of the Inquisitors fell in combat. Marrok was revived and fought well after the demise of the Empire. Some other Inquisitors' fates are also unclear.
It is unknown how many Imperial Inquisitors existed altogether in the Star Wars universe, but the number is believed to be 12. That's an important figure in numerology, especially when it comes to pop culture, history, and literature (12 Olympian Gods, 12 Apostles, 12 Knights of the Round Table, etc).
The Inquisitors' power in the Force varies by the individual. While the Grand Inquisitor is the strongest of the group, others, like the Tenth Brother, are considerably weaker. Vader and Sidious deliberately didn't teach the Inquisitors the true ways of the Sith, as their servants may then have truly become threats.
Many Inquisitors were ex-Jedi, from Reva Sevander to Barriss Offee. This raises questions about why so many Jedi were willing to turn to the dark side and join the Empire. It may have been an act of self-preservation after the Empire made it clear they were hunting down and executing any remaining Jedi.
Cal Kestis was originally a Jedi Padawan studying to become a future Jedi Knight at the Jedi Temple on the core world of Coruscant during the era of the Galactic Republic under the training of Jaro Tapal on a Republic Cruiser over Bracca.
By contrast, the Inquisitors were exempt from the Rule of Two, partly to protect the Sith code, but also to avoid the infighting that had led to their pre-Bane downfall.
The first grand inquisitor in Spain was the Dominican Tomás de Torquemada; his name became synonymous with the brutality and fanaticism associated with the Inquisition.
They were commanded to give their Jedi a chance to live - to turn on their fellow Jedi, believing the Empire's lives, embracing the dark side. They were the darkest Order 66 survivors of all, allowed to live because they were willing to abandon the way of the Jedi.
Order 66 marked the downfall of the Jedi, orchestrated by Palpatine to cut them off from the light side of the Force. Survivors like Yoda, Ahsoka, Obi-Wan lived on, facing the Empire's wrath as they struggled to continue their fight.
No, this is a stratocide, that is, the destruction of a certain social group. No, genocide is a broader concept. The destruction of the Jedi is a stratocide, since they were destroyed not for religious, but for purely political reasons. They were definitely destroyed for religious reasons.
