Emperor Norton's reign in San Francisco coincided with the advent and growth of opera in his adopted city. 

In one of the Emperor's earlier Proclamations, published in December 1865, he enjoins his subjects to attend and support the opera, writing: "The man that has no music in his soul is fit for Treason, Strategem, and Spoils. Let no such man be trusted....The Nation that supports music shows an advancement in Civilization and Refinement."

In April 1872, Emperor Norton returns to these themes in a Proclamation that focuses on a specific company, the Bianchi troupe, that had been identified with opera in San Francisco for nearly 15 years — but now was failing. 

Several episodes in the Bianchi story illustrate the challenges that beset the enterprise of opera in San Francisco during this period — challenges that lay at the heart of the Emperor's recognition that, in order for any opera troupe to nourish the public soul, it first must succeed as a business enterprise.
