Badges Wikipedia

 Now we look back history of badges, and will find more interesting event.          

  During the American Civil War, different battle units were ordered to wear custom  badges to distinguish their units. This was a visual clue to help the army stay organized as well as promoting solidarity among them. Having the troops share a marker also encouraged loyalty among members of the same unit.

 For More details, Button Badges were invented by a New Jersey company called Whitehead and Hoag in 1896. The Button Badge was born but not exactly as we know the button badge today as button badges had a cloth front. It started with a patch that was sowed on to jackets, mostly used in the Military to identify rankings and personnel.

 In World War I, the use of the  badges changed. Instead of being given out to everyone to help distinguish the units from one another,  badges were awarded selectively to individuals, to distinguish them for their exemplary service in the field. This use of  badges is still alive today, even though other uses have been introduced too.

 At the same time,  badges have come to be used by many other groups. Fraternities and sororities, for example, frequently give each of their members a pin, which they wear to their meetings and events. Businesses, sport teams, police and medical services, schools and a wide variety of other organizations also use badges, both as a sign of group membership and to mark outstanding achievement.
