Tolni, you seem to know a lot about the history of your country and the Balkans. Does your education system explore the complexities of Balkan history and the way Byzantine culture has shaped Bulgarian identity? Or does your knowledge come from other channels?
It's well-acknowledged, yes, although it depends on which grade we're talking about. For an example, early medieval history is taught in 5th and 11th grade, and there's naturally a difference in detail.
And, well, to be fair, most of the time, it depends on the teacher themselves. Nobody really teaches as the book exactly says; and considering the quality of some textbooks, might be better choice. Unfortunately, that can also create some...well, I wouldn't say wrong, but probably "biased" lessons. Especially when we talk about Kyriakos's favourite ruler of Bulgaria, Simeon.
^Bulgarian biased education perpetuates their national myth that Cyril and Methodios of Thessalonike were actually bulgarians, so bulgarians created an alphabet for all slavs
To be fair, that's being slowly shed away. Even the song in their memory mentions them as the "the two brothers from Solun", and it's recognized that they're from Solun. However, it's assumed that at least their mother was Slavic; and that due to the large amount of Slavs living there, they wanted to make an alphabet for them. With the help of a certain emperor, plus the desire for an alphabet from Great Moravia, the alphabet was made.
HOWEVER. The actual
Cyrillic script wasn't made by them. They created the glagolitsa, which is a ways off from what we know as Cyrillic. In fact, the Cyrillic script was made by his students in Great Moravia, which Boris accepted, in an effort to create Bulgarian clergy speaking a Bulgarian language.
