Hitler started declaring Mischlinge deutschblütig (of German blood), giving them an official Deutschblütigkeitserklärung sometime after the Nuremberg Laws in 1935. This form of clemency was given to those whom Hitler judged to look and act like persons of "German blood." Such a declaration freed a Mischling from most racial laws and allowed him to call himself deutschblütig in identification papers.
