Flag of the middle ages. The colors and clothes. Who with whom? Who who heard was at all times been an important feature in military conflicts. Was it only the hairstyle such as when the Suebi (Suebian knot). But Caesar’s armies, which since had the armor with the red color components as a sign of recognition to one? On the other hand, the SPQR which legitimized expelled the Roman legions as by people and Senate. It is not inventive.
The coat of arms was more developed out of necessity. At the times of the Crusades, the Sun proved to be the biggest enemy of the Knight. He was cooked in its own juices. So, armor (chain mail) was heated up by the Sun that you could fry like eggs on it. As protection from the Sun, the first Crusaders copied the kaftan of her opponents. I guess knowing about whose face the sun protection function. But also the increasing use of all-round closed helmets, which no longer face Tienanmen, contributed to its spread. The meaning of the colors.
Through the practical use this Cotte of the coat of arms for some time remained solid. Only internal disputes that often resulted in conflicts with each other, the colors of the banner was fought under whose leadership was carried as a differentiator. This evolved in the varied colours of today still known coat of arms course colors of the time. Medieval Surcoat or tabard. Sign on the tunic were worn first by Crusaders that served an order. This resulted in the so-called Crusaders frocks. These tunics are known as tabard. The most famous are the Crusaders with the Red Cross on a white background and the German knights with the black cross on a white background. But also the Knights Templar had a different color, the Red Cross on a black background. From the late Middle Ages, the color was always complicated. So there was the palewise frocks or but there were held the coat of arms of character of the coat of arms. What was available. The materials from which passed the frocks, were so diverse, how the materials themselves that were in the period available. Wool was the most easily accessible. Thus, the tunic of wool was also very common. Also the wool next to the property to warm and hold water, also a cooling effect in the summer heat. Combined with a linen lining, this effect was further reinforced. There was also still the pleasant smooth effect of a cloth, on the skin, to wear. But also frocks of linen and hemp were worn very much. Were made out of materials, which were easy to get. But also the more exotic materials such as silk or cotton found their way to the processing as a coat of arms. At the beginning and end. The coat of arms as a sign of dignity was worn to the outgoing middle ages. From the initial application only for the Knight, a commonly used facilities of the army was the later. Thus, also the city guard wore a coat of arms in the colors of the city in which they served. In the 17 century, the coat of arms was getting shorter and combined with the Jerkin. Importance as a distinctive mark lost the importance more and more. And uniformed aspect of the military upper hand won. At the present time, the coat of arms as a sign of recognition in the military has completely declined in importance.
