Janissaries at the time aren’t different than Mamluks. Devshirme system was first practiced during the rule of Murat II (1421-1444 1446-1451). Ottomans never used Christians in the army and Janissaryes are only a small part of the Ottoman army before they seiged the de facto rule of the state and at that times they are selected from Muslim families. Even those selected with devshirme system are only an ex-Christian, they are assimilated and converted to Bektashi Order. Bektashism isn’t a strict religious order, for example thanks to that some Tengriist and Zoroastrianism traditions are still practiced by some smaller communities of Anatolian Turks and Kurds. Apart from that If the family have only one son or if they live in a city or if the father is a craftsman or if the boy have a distinct appearance like mismatched eye colors, balding or deformities they are safe from devshirme drafts.
Around 1380s a grandson of Murat I( Davut, son of Shahzade Savci Bey) fleed to Hungary and later become a friend and an ally to John Hunyadi but i do not know whether he is a courtier of Sigismund or not. Maybe we can see him with Cumans (that archers with “funny” hats from the trailer).
@blackdreamhunk All Jews are share their ancestors with Arabs, your misconception originated from Beta Israel. By the way It isn’t something like Beta test of Israel, its mean “people of Israel”, Beta is anglicisation of “Beyt” an Arabic and Hebrew word. Like all other Jewish people they too inter married with locals.
About Tutankhamun, his birth name is Tutankhaten and if there any Pharaoh that also an Abrahamic Prophet it will be his father Akhenaten. Akhenaten abandon the old polytheistic Egyptian religion and formed Atenism, actually his name was Amenhotep but he change his name to Akhenaten at the same time. Atenism is a monotheistic religion but its more akin to Zoroastrianism than any Abrahamic religion. During his rule Tutankhaten abandoned the Atenism and change his to Tutankamun.
Abut Amen/Amun/Amon and ending word of prayer, Amun is a God from ancient Egyptian pantheon. He and other Egyptian gods are “archenemy” of both Atenism, Judaism, Christianism and Islamism. Amen is shared word of Hebrew and Arabic like Beyt and many other words.
In the alternate universe of Pharaoh Jesus, Jews, Christian, and Muslims would be end their prayer with aten instead of amen.
North Africans share more DNA and culture with other Mediterraneans than rest of the Africans. Beside Moors are result of melting pot in the Andalusian Chaliphate. By the way most important realm of Africa at 1403 isn’t Abyssinia, Axum, Granada or any Mediterranean country but Mali.
About the Coat of Arms, you can trace back all of those families to Crusaders and Spanish nobles of Reconquista, its mean their ancestor slay more Muslim than others. For medieval europeans both Africans, Arabs, Gypsies have black skin. Even the orginal Aryans (Persians and Kurds) and Turks from Central Asia was pictured as black skined in most of their art. Beside Coat of Arms have strict rules about colour, you can not pick a color at whim. Most logical choice to represent the decapitated Muslims in Coat of Arms is black.
