Heralds were official messengers in medieval times, responsible for delivering important news and announcements. They played a crucial role in communication, especially during wars and tournaments, where they would proclaim the names of knights and their achievements. Heralds were also tasked with maintaining records of coats of arms and family lineages, which were essential for identifying noble families. In addition to their communication duties, heralds often served as diplomats, negotiating treaties and representing their lords. They wore distinctive uniforms that displayed their heraldic symbols, making them easily recognizable. Their work laid the foundation for modern heraldry, the study of coats of arms and symbols used to represent individuals and families.
