How Did Hitler Deal With the Problem?
When Hitler took power in 1933, anti-Gypsy laws remained in effect. As the Nazis immediately began to implement their vision of a new Germany — one that placed "Aryans" at the top of the hierarchy of races and ranked Jews, Gypsies, and blacks as racial inferiors. Under the July 1933 "Law for the Prevention of Offspring with Hereditary Defects," physicians sterilized against their will an unknown number of Gypsies, part-Gypsies, and Gypsies in mixed marriages. Similarly, under the "Law against Dangerous Habitual Criminals" of November 1933, the police arrested many Gypsies along with others the Nazis viewed as "inferiors" - prostitutes, beggars, chronic alcoholics, and vagrants - and imprisoned them in concentration camps.
The Nuremberg racial laws of September 15, 1935, did not mention Gypsies, but in commentaries interpreting these laws, Gypsies were included, along with Jews and "Negroes," as "racially distinctive" minorities with "alien blood." As such, their marriage to "Aryans" was prohibited.
In December 1937 a decree on "crime prevention" provided major police roundups of Gypsies. In June 1938, 1,000 German and Austrian Gypsies were deported to concentration camps at Buchenwald, Dachau. A year later, several thousand other Austrian and German Gypsies became inmates at Dachau, and Buchenwald concentration camps. In the camps, all prisoners wore markings of various shapes and colors, which allowed guards and camp officers to identify them by category. Gypsies wore the black triangular patches, the symbol for "inferiors," or green ones, the symbol for professional criminals, and sometimes the letter "Z."
In October of 1939 in the middle of the turmoil of the outbreak of war Hitler ordered widespread "mercy killing" of the sick and disabled. Code named "Aktion T 4," the Nazi euthanasia program to eliminate "life unworthy of life" at first focused on newborns and very young children. Midwives and doctors were required to register children up to age three who showed symptoms of mental retardation, physical deformity. The decision had to be undisputed. In cases where the decision was not undisputed the child was kept under observation and another attempt would be made to get a common decision.
The Nazi euthanasia program quickly expanded to include older disabled children and adults. Hitler's decree of October, 1939, gave” the authority of certain physicians to be designated by name in such manner that persons who, according to human judgment, are incurable can, upon a most careful diagnosis of their condition of sickness, be accorded a mercy death." A total of six killing centers were established including the well known psychiatric clinic at Hadamar.
