en procession

A procession is an organized body of people walking in a formal or ceremonial manner. A procession may be arranged for a variety of purposes, including to advertise something, signal a change in government, display a group's power, show solidarity for a cause, mark the beginning or end of an event such as a wedding or funeral, entertain a crowd, or practice a religion. Processions have been an aspect of celebrations and ceremonies since ancient times, and they are practiced in some form throughout all cultures. They often involve a mode of transport, such as a carriage or a car; music or vocalizations, including a choir or a marching band; a visual signal of a hierarchy within the precession; and the display of eye-catching items like banners.
