"Minhag Anglia" does also have wider connotations re the structure, and hashkafa, of English-Judaism more generally; see United Synagogue, London Beth Din, Jews College.
This may be true, but in itself this does not support a claim of Babylonian origin as argued by Gaster: as pointed out by Louis Ginzberg[9] the Siddur Rab Amram had itself been heavily edited to reflect the Old Spanish rite.
The earliest recorded form of the Ashkenazi rite, in the broadest sense, may be found in an early medieval prayer book called Machzor Vitry.
The Old French rite mostly died out after the expulsion of Jews from France in 1394, but certain usages survived on the High holidays only in the Appam community of Northwest Italy until shortly after WWII, and has since become extinct.
[citation needed] The liturgical writings of the Byzantine Jewish, especially the piyyutim (hymns), found their way through Italy to Ashkenaz and are preserved to this day in most Ashkenazi mahzorim.
