Main Space Marine Chapters
The Space Marine Chapters of Warhammer 40K are numerous and are divided in three main categories: First Founding Legions (Loyalist), Notable Successor Chapters, and Renegade/Traitor Chapters. Below is a compilation of the most notable Chapters of Space Marine based on categories.
First Founding Legions (Loyalist)
Before the Horus Heresy, the Emperor created 20 Legions, referred to as First Founding Legions or Loyalists. However, after the Horus Heresy, the remaining legions were divided into smaller Chapters under the doctrine of Codex Astartes. Below are the surviving Chapters of the First Founding Legions.

The Black Templars originated from the Imperial Fists after the Horus Heresy, and they are a zealous and crusading Chapter. They do not follow the Codex Astartes doctrine on numbers and are usually at war, launching attacks in the galaxy.
Their combat style is melee, in which they mobilise their numbers of initiates and neophytes. They are fiercely anti-psyker and will not suffer witches or mutants to live.

How many Space Marine Chapters are there?
It is estimated that 1,000 Space Marine Chapters exist in the Imperium. The estimate is based on Codex Astartes, which has Legions that are further divided into Chapters. 1,000 is not a fixed number because the number of Chapters fluctuates due to elimination, creation, and unrecorded successors.
Are there only 1000 Space Marines per Chapter?
Not all Space Marine Chapters adhere to the 1,000 rule of the Codex Astartes. Some Chapters maintain 1,000, while others have less or more than 1,000.
What Chapter has the most Space Marines?
Black Templars, which does not adhere to the 1,000 rule of the Codex Astartes, is believed to have the most Space Marines, ranging between 6,000 and 10,000.
What is the most powerful Space Marine Chapter?
There is no particular Space Marine Chapter considered the most powerful among them all. However, the most influential ones include Black Templars, Space Wolves, Dark Angels, and Blood Angels.
What happens if a Chapter is destroyed completely?
A Chapter can be destroyed completely if it is annihilated in war, and therefore, it becomes extinct. However, later, it may be revived if its gene-seed was stored.
Space Marine Chapters have unique legacies determined by their Primarch, doctrines, and unique situations. The warriors are committed to the values and purpose of their Chapters and continue to define the future of the Imperium. In the seemingly unending war against darkness, Space Marines are the greatest defenders of the Imperium.
