Economic life flourished in the city of Balis, like other ancient Euphrates cities on both banks of the Euphrates, especially at the beginning of the Umayyad era and through the Abbasid era. It lies at the crossroads of rivers and land in the middle of a rich agricultural region, which explains the economic, agricultural and commercial prosperity it apparently experienced during most of this period. The city of Balis also knew some of the traditional industries that existed in the Levant at that time, thanks to its location on the Euphrates, which made it a port and a center for commercial transportation. The research included an introduction and four axes. In the introduction, the researcher dealt with the site of the city of Pulse. In the first axis, we talked about agriculture, the second axis, in which the researcher dealt with trade and industry, the third axis, in which we dealt with the economic crises that the city of Pulse was exposed to, and the fourth axis, in which we talked about the karmic merchant Muhammad bin Muslim Balsi and his commercial role.
