People are living in the pain of war, and social and economic development has basically stopped. Only when a person has enough to eat and wear warm clothes can he enjoy leisure and develop interest. Obviously, no one has the energy to develop art now. The famous "Crusade" took place in this period. Roman Catholicism launched an expedition to Islam in the name of recovering the holy land in Jerusalem. One word: "kill", two words: "bloody" and "cruel". After nearly 200 years of fighting, Jerusalem finally fell into the hands of Muslims, but Byzantium (East Rome) was wrongly destroyed.
The mysterious "knight" was also in this period. Cavalry with formal military training was called knight, which later evolved into honorary title. Three famous knights: hospital, temple and Teutonic. Hospital knights mainly take care of the wounded and pilgrims, which has continued to this day. The red cross symbol comes from that era. The Sovereign Military Order of Malta is a successor or member of the United Nations. It's not even on the map. The only territory is the 0.0 12 square kilometer building "Malta Palace".
The Knights Templar is only responsible to the Pope, and is not under the command of kings and local bishops. They are super-rich knights and owned more than 9,000 properties at the end of 12. Even the king envied the popularity of this tree. One Friday, the French king's army wiped out the Templars, so there was "Black Friday". From 65438 to 0939, Sutton Lake Cave was discovered in about 625 AD, Roman art reached its peak, Gothic art sprouted, vernacular appeared, and Latin classicism, Latin poetry, architecture, sculpture, drama, law, philosophy and education all developed. From these viewpoints, the Middle Ages were actually developing.
