:Amandajm said: "...the editors here are not going to add anything as lengthy and detailed as you have proposed. This is much too detailed for this article."  Really? What you say about the Carolingian Empire. Quotes:

 :Compared with the place, which is given in the article for the Frankish Empire, my suggestion about Bulgarian Empire is dwarf. Nobody of editors here did not answer me why about the Carolingian has so detailed information, but about Bulgarian Empire they always say "too much detailed". This is a double standard, by me. Why? Above I mentioned pages of the textbook university , where it is said: Eugenia Pancheva in "Theory of Literature", 2005, p.44 (ISBN:9545293497) (designed for the study of literature in universities): "Literature and art of Carolingian Empire has much lower development than in Constantinople and Preslav..." "Literature in Bulgaria from this period is at a higher level than Carolingian and Gothic, because of the early development of Bulgarian national identity and the system of caesaropapism, which reduced the influence of the church...", "...in the Frankish Empire philosophers was limited to the study of nature and repeated many of the existing views on this issue. Therefore, in the Frankish Renaissance lacking author as Chernorizets Hrabar, who has the status of apologist or classic philosopher... , "In the 10th century Bulgarian Empire has its own independent church, own independent ruler and own writing system, which make it the most powerful and influence state in Europe.". 
 :Even militarily Frankish Empire was weaker than Bulgaria. This is one example by that: :https://en.wikipedia.org/wiki/Omurtag_of_Bulgaria#Relations_with_the_Frankish_Empire 
 :My conclusions from all discussion and all the sources that I found: 
 ::1. In the 7-10 and 13 century Bulgarian Empire was the most powerful country in Europe. FBE defeated all other empires - Asparouh defeated the Byzantines at Ongal (680) Tervel defeated the Arabs and save Europe from the Muslim invasion (718 - this is an event of great importance for the history of Europe and the world. I do not know why it is not mentioned), Omurtag defeated the army of Frankish Empire (827) , Simeon I the Great defeated the Byzantines in the biggest battle in medieval Europe - Aheloi (917) and many others. 
 ::2 . The culture of the Bulgarian Empire has a huge influence over all Eastern Europe (9-11 and 13-15 century) and partly over Western Europe (Tarnovo Artistic school, 13-14 century). Preslav and Tarnovo schools are the most influential institutions in Europe during the Middle Ages. 
 ::3 . The frescoes in the Boyana Church are determined by experts, who I cited in the discussion, as a "peak of medieval art and the beginning of the Renaissance". But in the article has not yet said nothing about it. 
 ::4 . The architecture of the Bulgarian capital Pliska. Stoyan Popov in his book " The Castle in Europe during the Middle Ages" (which I citedq when added information about Pliska) say that Pliska is a city built of stone, as nowhere in medieval Europe. The castles in Western Europe appeared only in the 11th century , in the high Middle Ages. Lapping ahead of Western Europe with 4 centuries ! The same argument still maintain archaeologist Ovcharov and many other historians and experts in urban planning. The Great Basilica of Pliska is the largest cathedral in Europe during the Early Middle ages. The area of the central cathedral is 2920 square metres, the all Pliska complex is 27 000 sq. metres. And as always - nothing about it in the article. 

 *Summary  
 :The medieval Bulgarian state play a major role in European history , culture and art. But excluding Amanandajm, the editors here will never added information about Bulgaria in the article. If someone write something related to Bulgaria, it will be deleted immediately. Even to presented a mountain of sources, it will be deleted. It is a violation of NPOV. These actions lead me to believe that this article is ruled by editors, who have nationalist bias and negative attitude towards Bulgaria, which is unacceptable in a place like Wikipedia, by me.
