 Abraham Lincoln's funeral cortege solemnly proceeded along Pennsylvania Avenue in 1865; only weeks later the end of the American Civil War was celebrated when the Army of the Potomac paraded more joyously along the avenue.As well as being the scene of official functions, Pennsylvania Avenue is the traditional parade and protest route of ordinary citizens.During the depression of the 1890s, for example, Jacob Coxey marched 500 supporters down Pennsylvania Avenue to the Capitol to demand federal aid for the unemployed.
