Following on from my earlier ponderings on the development of
orcs in
Dungeons and Dragons and related franchises, I am now going to focus on a very similar creature: the goblin. Goblins have, perhaps, changed less than orcs over the years since their first introduction into the game, but change they have, and they are a very common low-level opponent, one that's generally intended to be marginally weaker than a starting player character, and thus a threat in large numbers without being a complete walk-over when encountered in smaller groups.
The term "goblin" is, of course, an ancient one in English, referring to a (usually) malevolent magical being that is typically small and misshapen; a sort of evil fairy. As with orcs, the more modern conception of goblins comes from J.R.R. Tolkien. Indeed, Tolkien uses the word as simply another word for "orc", mainly as the term that hobbits use for that race. The fact that the word therefore ends up being used more frequently in
The Hobbit, in which these particular antagonists seem less of a serious threat than their counterparts in
Lord of the Rings do, likely combines with the original folklore meaning of the word to produce the "like orcs, only weaker" idea first used in D&D.

Goblins appear in the very earliest editions of D&D, at first without much in the way of description. By the time of the "Advanced" edition, they are part of a distinct hierarchy of five evil tribal humanoid races, forming the second step on the chain, one slot below the orcs. Statistically speaking, they are extremely similar to orcs, but just marginally weaker: they are slower, have one less hit point, a 5% lower chance of landing a blow on an opponent, and inflict, on average, one less point of damage when they do so. In practical terms, this doesn't make a huge difference, but it could be just enough to turn the tide in an otherwise close battle (as is likely at low level).
