Analysis of information sources in references of the Wikipedia article "Palestinian minhag" in English language version.
Two groups of rituals, or Minhagim, are to be distinguished, the Palestinian Minhag and the Babylonian Minhag. 1. The Palestinian group includes: (a) the German ritual; this is itself divided into two rituals, the Western or Minhag Ashkenaz, and the eastern, or Minhag Polin. The Elbe River forms the boundary between these two. (b) the Italian Minhag, perhaps the oldest branch of the Palestinian ritual, (c) the Romanic Minhag, or, more accurately, the Rumelic or Greek ritual; this ritual of the Balkan countries has retained most features of the Palestinian Minhag.
Thus, the acceptance by the Ashkenazi Jews of many elements of the Palestinian minhag and by the Sephardic Jews of many elements of the Babylonian minhag resulted in distinctive rites, which are also referred to as minhagim.
