man what is interesting is this
Arbanites existed to Sterea from the time of Ducchy of Athens,
at Theba from around 1240 Ad by invitation of Latin rulers of 4rth crusade De la Roche family,
the title was Half baron of Theba
baronia de Teba
What is interesting?
Why Plague hit only the Greeks and not Arbanites?
at peloponese
Destroyed doctoras always shit happens,
and if the work is from the Academy of Athens, surely worths nothing,
cause the Arbanites who entered Peloponese
as I said enter around 1390 by license
and later at 1410 by Palaiologos emperor's license
So Arbanites Already Existed when plague stroke at S Greece, after 1340 and were already at the maximum around 1400.
what were they? Immune to black death?
Besides
Plague is also connected with Crusaders and stroke Adriatic coasts more than Greece (Dubrovnik)
so the theory you provide, even written by a Greek seems to be just an Hypothesis
man plz
it is just silly to say that Greeks died of plague
and Arbanites were immune
so they invite them to 'empty land',
