Guilds of Ravnica
The Guilds of Ravnica are ten sociopolitical factions with their unique identities. In the city and plane of Ravnica, some individuals are affiliated with one of them. Each guild has its own distinct ideology that unifies its members with one another and the guild itself, functions and purposes, as well as a structure, if any at all.
The ten Guilds
The guilds are:
Certain characters from the city and plane of Ravnica or associated with Ravnica and its guilds, such as the unguilded Krenko  and Yeva of the Selesnya Conclave  are not featured in any of the sets from those blocks, however, but bear the indelible influence of the guilds of Ravnica.
Collectively, the guilds of Ravnica have ruled the plane for 10,000 years, since the signing of the ancient and magically potent Guildpact, a binding spell, document, and contract, that details the specific role and responsibilities of each of these guilds.
Prior to the events of the novel Dissension, guilds would try to find loopholes so as to increase their power without breaching it. Following Dissension, however, guilds are no longer bound by the document; and, although the guilds themselves have not completely collapsed, their influence on the city and plane of Ravnica has diminished, as demonstrated in the Return to Ravnica block storyline arc.
After the breaking of the Guildpact, Teysa Karlov of the Orzhov Syndicate drafted a new, non-magical document amongst the guilds in the interest of cooperation and stability for Ravnica; however, the powerful and wealthy became even more powerful and wealthy and, by and large, the guilds had disappeared.
Gradually, the general populace's distrust of the guilds diminished and, once again, the guilds returned and became ascendant.    Old guild and factional loyalties rekindled, and new guildmasters assumed the mantle of a majority of the guilds; only the Izzet League, Orzhov Syndicate, and the Cult of the Rakdos retained their original guildmasters.
In the events of the Return to Ravnica block, planeswalker Jace Beleren collaborated with Niv-Mizzet of the Izzet League, while planeswalker Gideon Jura was in alliance with Aurelia, commanding Boros Legion soldiers.
