Despite the fact that it was officially founded in December 1834, the Commercial Association of Porto which dates back to the twelfth century, when trade and tradesmen, especially in coastal areas, were gaining more power.
Over the centuries, owing to its strategic location and the entrepreneurial spirit of its people, the city of Porto acquired great importance, becoming an important financial center in Europe and the world. It was at this stage that a shared “Trust fund” was established, created by merchants to cover risks and shipment losses of their commodities. This fund was recognized in 1295 by King Dinis and in 1402 by King John I.
However, until 1834 there was no organization of traders with legal status and competent to meet the needs of local entrepreneurs. At this point, meetings, the exchange of information, business and auctions were held in the “Juntina”, located at the then Rua dos Ingleses. After the Liberal Revolution of 1822 and the enactment of the Commercial Code, the Juntina was the basis of the founding of the Porto Commercial Association, which is currently the second oldest Chamber of Commerce and Industry in Portugal mainland.
