Artifacts of History is the fourth expansion for Innovation. Artifacts of History features unique artifacts from history, such as the Declaration of Independence. These cards feature powerful dogma effects, but are difficult to wield.

Artifacts of History is simpler than the other expansions released so far, Unlike the other expansions, there are no significant new mechanics on the cards. Instead, the new artifact cards are difficult to obtain but have very powerful effects. The artifacts are especially useful for players who are behind.

There are some minor new mechanics. One of them is the compel effect. This effect is similar to the demand effect of the base game, except that it affects players who have more icons of a given type instead of fewer.
