Once again your incorrect the Solomonic myth wasn't created by amda seyon or the Amharas the Aksumite believed indeed that they were descendants of Israelites according to their 6th manuscript ( 500 years before the alleged creation of the solomonic myth) and DNA studies have proven that they share more DNA with people from levant than with Yemenis which fits perfectly with the solomonic theory.
DNA clues to Queen of Sheba tale
The DNA of some Africans provides clues to the origins of the Queen of Sheba legend, say scientists.www.bbc.com
"By analysing the genetics of Ethiopia and several other regions we can see that there was gene flow into Ethiopia, probably from the Levant, around 3,000 years ago, and this fits perfectly with the story of the Queen of Sheba."
"Genetic research suggests Ethiopians mixed with Egyptian, Israeli or Syrian populations about 3,000 years ago."
Tigrayans were the real axumites and not Amhara.They were the originial ruling class.
The solomonic myth is a myth just like the oromo comming from madagascar narrative.
This myth probably came about when Axumites/ Abysinians took over Yemen and ruled it after heavily marrying the yemenis even though they were still darker in complection to Arabs with the admixture.
Empress dawit almost destroyed the real axumite kingdom 8n the 10th century and destroyed churches that is the real turning point.Its after this time that Amhara might have come to power after the Tigrayan dynasty was weakened.
Also amhara absorbed alot of groups as they are not even homogenous within themselves.They seem to be a mix of semitic,cushitic and nilotic backgrounds.
Under Haile Selasie he favoured amhara to cleanse themselves by marrying out of the community to make them look exotic cute and intelligent.
I was told of how amhara soulders used to steal somali children in the ogaden and how foreigners would sleep with amhara women.This practise is common even today in Ethiopia.
