In my thesis, I am going to evaluate a quite well-known period of early modern English history. Cromwellian and Restoration England might seem to be an unambiguous topic to reassess for researchers, yet, I think it is worth arguing for the new point of view which I am going to support in my work. English foreign policy is very complicated and difficult in the second half of the seventeenth century. However, we could also state that it had never been easy to get on through the seventeenth century for England.
