"Articles under the heading Arier were included in the big popular encyclopaedias of Brockhaus and Meyer from 1864 and 1867 respectively, and the Arier is defined from the start as Indo-Germanic. The 14th edition of Brockhaus states specifically that it is better to apply the term Arier only to "Asian Aryans" and to use the term Indo-Germanic or Indo-European to describe the "European Aryans"."
