Etymology: The word is simply "uncontroversial" with the adverbial suffix "-ly" attached, so its story is mostly the story of its two parts. The prefix "un-" goes back to Old English, where it meant "not" and could be attached to almost any adjective to negate it. The adjective "controversial" came into English from Latin "controversia", a word meaning a dispute or debate, built from "contra" ("against") and "vertere" ("to turn"), so the original sense was a matter that turns one side against the other. The suffix has a longer lineage. "-ly" descends from Old English "-līċe", which was itself a form of the noun "līc" meaning "body" or "form", so an older phrase like "in a manner of" a quality gradually shrank into a simple adverb ending. Middle English reduced the Old English form to "-ly", which is why the ending now appears on so many adverbs.
