A chamber of commerce (or board of trade) is a form of business network, for example, a local organization of businesses whose goal is to further the interests of businesses. Business owners in towns and cities form these local societies to advocate on behalf of the business community. Local businesses are members, and they elect a board of directors or executive council to set policy for the chamber. The board or council then hires a President, CEO or Executive Director, plus staffing appropriate to size, to run the organization.
The first chamber of commerce was founded in 1599 in Marseille, France. Another official chamber of commerce would follow 65 years later, probably in Bruges, then part of the Spanish Netherlands.
The world's oldest English-speaking chamber of commerce is the Jersey Chamber founded in February 1768, the same year the New York City Chamber was founded, The oldest known existing chamber in the English-speaking world with continuous records, the Glasgow Chamber of Commerce, was founded in 1783. However, Hull Chamber of Commerce is the UK's oldest, followed by those of Leeds and of Belfast in Northern Ireland.
As a non-governmental institution, a chamber of commerce has no direct role in the writing and passage of laws and regulations that affect businesses. It may however, lobby in an attempt to get laws passed that are favorable to businesses.
Membership in an individual chamber can range from a few dozen to well over 800,000, as is the case with the Paris Île-de-France Regional Chamber of Commerce and Industry. Some chamber organizations in China report even larger membership numbers. Chambers of commerce can range in scope from individual neighborhoods within a city or town up to an international chamber of commerce.
