Re-education

Re-education is to educate again or anew so as to rehabilitate or adapt to new situations.

It has been used as a political term, particularly in Maoist regimes, especially following revolutions or successful suppression of counter revolution. The losers in the struggle are sent to work camps for indoctrination under the title of re–education.

Re-education is a term with considerable sinister meaning. Under the Khmer Rouge in Cambodia, "re-education" generally meant death in the killing fields. The brainwashing torture in Orwell's 1984, though not referred to as such, is another example of "re-education" in the sinister, political sense.
