The protocole means the code of conduct that people have to adopt according to their social position. This means that there are people who are invited to cocktail parties for example because of their rank.

Zizka was a famous general in Bohemia who formulated the military code of conduct we use today. He also mounted light cannon on wagons that could be horse-drawn into a circle, forming a mobile fortress, much copied in the pioneer settlements of the US and South Africa, and enlisted women in his army. Zizka is also remarkable because he was completely blind and died, not in battle, but of the plague shortly before his last, and unsuccessful, battle. He is revered in Eastern Europe.
