Intelligence (Culture) (5e Skill)
From D&D Wiki
Your Intelligence (Culture) check measures your familiarity with a broad range of customs and proprieties in various societies. You can roll this check to know the proper etiquette in a social encounter, to understand the values of an intelligent creature's culture, or to identify the likely origins of a weapon or work of art.
Any time you might gain proficiency in the History skill, you may instead choose to gain proficiency in Culture.
