Jamestown and Plymouth were both permanent English colonies.They both didn't start out as royal colonies.Both were started in the early 1600s (Jamestown=1607, Plymouth=1620) Colonists at Jamestown and Plymouth suffered greatly in the beginning- the colonists at Jamestown weren't used to hard labor they had to do and suffered from famine/illness/ect while the colonists at Plymouth arrived later during both the same year and suffered from an extremely harsh winter. Also, a conflict between them included economical issues. Plymouth's issues included economy and religion,and while Plymouth wasn't dependent, Jamestown was.
Hope this helps (:
