Where I can get information about joint stock companies with government shares?

Joint Stock Companies were the early version of corporations. The English formed joint stock companies so people could invest in forming colonies in North America and other locations. The Virginia Company was one of these. Settling of the colonies was a capitalist venture, moreso that being an activity of the English government. The Company appointed the governor and the ruling council. Spanish and French colonies, on the other hand, were developed by those nations, rather than as private companies owned by people. You can find this in writings about U.S. colonial history.
