No one expects the Spanish Inquisition!
This unorthodox list of “Thieves’ Guilds in History”, in Pathfinder’s Council of Thieves (2010), was regarded with some suspicion. “Surely this can’t be right!,” a friend of mine thought, and showed it to me in disbelief. But I’ll defend it, because it does what it says on the tin. Just the small print of the tin, not the large title. It ‘s not literally a list of historical thieves’ guilds, but it’s definitely a list of parallels, “organisations that can be conceptualised as thieves’ guilds” to quote the text, and whose characteristics might resemble your standard fictional Thieves’ Guild in some regard, I would add. If we look at it that way, it’s not that much of a stretch.
No joke at all, depending on how we define organised crime, we might unintentionally include all sorts of organisations, because as it happens, the features, structure, and tactics of the Mafia (and the Yakuza and the Triads etc) can also be found in corporations, sovereign states, and so on. OPEC qualifies, and so does NATO and the IMF. The IMF is the probably the worst, and it would be my first choice if I was making that list. The blackmail of entire countries and their subsequent strangulation via debt isn’t very different (of better) than the blackmail of individuals and their subsequent murder via Colombian necktie.
In rural areas, resistance movements of all kinds (and rebel groups, irregular liberation armies, what have you) operate like bands of bandits. It’s inevitable, it simply doesn’t work otherwise. Their ultimate goal may vary wildly, ranging from admirable to appalling, but if the intermediary goal is “kick out the occupying army and/or defeat the national one with guerilla warfare”, what are they gonna do? Work 9 to 5 at the office and sabotage the bridge at 6? No, they need hideouts in the wilderness, and friendly locals, and supplies that they’ll acquire by any means necessary. Just like bandits.

So again, this is not a list of historical thieves’ guilds by any means (there is no such thing), but we can take it as food for thought, a nudge for more research, and inspiration for worldbuilding.
