From Wikipedia:

1. Woke is an adjective derived from African-American Vernacular English (AAVE) meaning “alert to racial prejudice and discrimination”. Beginning in the 2010s, it came to encompass a broader awareness of social inequalities such as sexism, and has also been used as shorthand for American Left ideas involving identity politics and social justice, such as the notion of white privilege and slavery reparations for African Americans.

The Wikipedia link is an excellent history of the use of woke going back to African American usage around the start of the twentieth century. It basically took 100 years for White folks to “wake up” to what Blacks had been horrifically suffering from for centuries in America.
