Founded in 1871, this long-standing business association has been closely tied to the growth of commerce in Manaus and the wider Amazon region. Its story reflects both the rubber-boom era and the continuing effort to represent local entrepreneurs.

The Associação Comercial do Amazonas (ACA) was founded on June 18, 1871, when Manaus was still a small provincial center beginning to expand as a trading hub in the Amazon. On its official history page, the association presents itself as part of the region’s economic formation, emerging at a time when local commerce was becoming more organized and influential.
According to the ACA and the Confederation of Commercial Associations of Brazil, the institution was created to defend the interests of the business community and has remained active across commerce, industry, and services. Its first president was José Coelho de Miranda Leão, and over time the association became one of the most traditional representative entities in Amazonas.
Today, the ACA describes itself as a meeting point for entrepreneurs and partner institutions, offering representation and support for the productive sector. Its long history gives it a special place in the public life of Amazonas, linking past cycles of regional development with present-day business advocacy.
