"Woke" is a word, which describes/refers to a concept. The use of the word may be culturally and temporally specific (and that usage, like all use of language, may change over time), but the concept is one found in many different cultures and communities across time and space - put simply and broadly, the notion that one needs to "wake up" or "awaken" to what is actually happening. There are ways of describing this in many different languages. So while the current use of the word "woke" within the US may indeed be traced back to the African American community, the concept/idea has a much longer and broader history than that.
