During a period of French influence in Genoa, Governor Jean Le Meingre (Boucicaut) promoted the creation of Compere di San Giorgio—associations of public creditors tied to specific revenue streams. These arrangements helped organize and service Genoa’s growing public debt and set the stage for a single debt-management institution later.
The Casa di San Giorgio took up residence in Palazzo San Giorgio, a major civic building on Genoa’s waterfront. Locating the institution there reinforced its close connection to customs and other key revenue sources used to service public debt.
Genoa formally established the Casa delle Compere e dei Banchi di San Giorgio to consolidate and manage public debt that had become difficult to handle through many separate “compere.” The new institution organized creditor claims (often represented by tradable shares known as luoghi) and tied repayment to defined public revenues.
The institution was authorized to operate a public bank that accepted deposits and provided credit and transfer services. This expanded San Giorgio from a debt-management body into a major financial intermediary for merchants and the state.
San Giorgio began to gain territorial authority as collateral and compensation for managing Genoa’s finances, starting with the acquisition of Pietrasanta and Mutrone. This was an unusual step for a financial institution: it could govern territory and collect revenues, not just run accounts.
The assignment of Palazzo San Giorgio to the institution was formally sanctioned, strengthening its administrative base. Over time, the building and the institution became closely identified in Genoa’s public life and in outside accounts of Genoese finance.
Genoa transferred administration of Corsica to the Casa di San Giorgio. The change reflected a practical bargain: the institution that managed debt and revenues also took on governance to stabilize and extract income from an important territory.
San Giorgio’s territorial role extended beyond the western Mediterranean to Genoese holdings around the Black Sea. These overseas dominions, including Caffa and related outposts, were not permanent; by 1475 San Giorgio’s control over these Black Sea territories had ended, narrowing its territorial footprint.
After more than a century of involvement, San Giorgio’s direct governance of Corsica ended and authority returned to the Republic of Genoa. The shift marked a contraction of the institution’s quasi-sovereign role, even as it continued to manage financial functions.
The Leggi delle Compere (laws governing the compere and the institution) were published, helping formalize structures, responsibilities, and procedures that had evolved over time. This kind of codification supported continuity and credibility for an institution that managed public debt and major revenues.
In 1797, the old Republic of Genoa was replaced by the Ligurian Republic, a French client state. In this new political order, San Giorgio lost the level of autonomy it had built over centuries as a semi-independent manager of revenues and debt.
By 1805 the Casa/Banco di San Giorgio was definitively suppressed and its assets were liquidated under French imperial administration. Its closure ended one of Europe’s longest-lived early public banking institutions, known for combining public-debt management with deposit and transfer banking over several centuries.
The Ligurian Republic was incorporated into the French Empire, tightening centralized control over Genoa’s former institutions. This annexation helped set the conditions for formally winding down older corporate bodies tied to the previous republic.
