A "Cavalcade of German Americans" was celebrated in 1958 and the annual Steuben Day Parade was commenced that year and in 1959.
Steuben's September birthday is the same date as the signing of the U.S. Constitution, so it is also called "Constitution Day" or "Citizenship Day."

PARADE OF 15,000
200,000 Line 5th Avenue
to Watch March - Start
Delayed for the Mayor
By MICHAEL CLARK
To the music of forty bands, 15,000 German-Americans paraded up Fifth Avenue yesterday afternoon. It was General von Steuben Day, and the weather was sparkling clear.
Billed as the second annual "Cavalcade of German-Americans," the parade included forty-seven floats, many of them depicting contributions of German immigrants to the building of America.
The Steuben Day Parade - resumed as an annual event last year after a lapse of forty years - honors Baron Friedrich Wilhelm von Steuben, Prussian-born general in the American revolution.
