The colonial assembly shared power with a royally appointed governor. On a more local level, governmental power was invested in county courts, which were self-perpetuating (the incumbents filled any vacancies and there never were popular elections). As cash crop producers, Chesapeake plantations were heavily dependent on trade with England. With easy navigation by river, there were few towns and no cities; planters shipped directly to Britain. High death rates and a very young population profile characterized the colony during its first years.
