 Some town charters explicitly granted medieval towns the right of self-governance.Commercial endeavors were "not" among the entities incorporated in the medieval era, and even risky trading companies were originally run as common-law partnerships rather than corporations; the incorporation of the East India Company monopoly in 1600 broke new ground, and by the end of the century, commercial ventures frequently sought incorporation in Europe and the American continent.By the 19th century, the direction of British and American corporate law had diverged; British law of this period (such as the Joint Stock Companies Act 1856) appeared to focus more on corporations that more closely resembled traditional joint ventures, while American law was driven by the need to manage a more diverse corporate landscape.
