On September 15, 1887 Philadelphia began its celebration of the 100th anniversary of the Constitution. An excerpt from the article:
"For Philadelphia and the nation, the Constitution’s major anniversaries often occurred in times of conflict that notably inspired and informed the celebrations. While the Golden Jubilee in 1837 passed largely unobserved, September 17, the date on which the Convention signed the Constitution, was recognized occasionally throughout the early 1800s. Such commemorations often served political purposes; in the 1850s, for example, Philadelphia’s Democratic Party staged commemorations as a counterpoint to the anti-immigrant nativist politicians who dominated city government. Similar tributes also cropped up during the strife of the Civil War.
In contrast to these limited observances, the Constitution’s 100th anniversary in 1887 was treated as an opportunity to demonstrate national progress in a three-day spectacle reminiscent of the 1876 Centennial International Exhibition. A lack of Congressional interest and funding effectively ceded responsibility for the festivities to Philadelphia, which organizers styled the “Mecca of America,” much to the chagrin of rival cities such as New York. In an era of rising immigration and agitation from groups including laborers, suffragettes, and African Americans, proclamations of national unity and reverence for the storied Revolutionary past dominated the proceedings, which began on September 15 with a Civic and Industrial Procession on Broad Street. The procession featured 21,029 representatives from the city’s trade and commercial organizations, as well as 2,106 musicians and 497 massive floats depicting key moments in American history. A military parade, the largest in the nation’s history, followed the next day and celebrations concluded on September 17 at Independence Square. Attended by President Grover Cleveland (1837-1908), the ceremonies included a Marine band led by John Philip Sousa (1854-1932) and speeches that venerated Constitutional principles while overlooking any conflict regarding the document’s drafting and ratification."
