In 1800 financial power in France was in the hands of about ten to fifteen banking houses whose founders, in most cases, came from Switzerland in the second half of the eighteenth century. These bankers, mostly Protestant, were deeply involved in the agitations leading up to the French Revolution. When the revolutionary violence got out of hand, they orchestrated the rise of Napoleon, whom they regarded as the restorer of order. As a reward for their support, Napoleon, in 1800, gave these bankers a monopoly over French finance by giving them control of the new Bank of France.
Linkage with the ESCB
On 1 June 1998, a new institution was created, the European Central Bank (ECB), charged with steering the single monetary policy for the euro. The body formed by the ECB, and the national central banks (NCB) of all the member states of the European Union, constitute the European System of Central Banks (ESCB).
The ESCB is an institutional framework of a single monetary policy for the euro. According to the Banque de France's website, the "sharing of responsibilities between the ECB and the NCBs is based upon significant decentralization of the conduct of the ESCB's single monetary policy".
