Barton Slisz: Between the 15th and 16th centuries there is in strict terms no time at all, not even a millisecond. Possibly you want to ask about the time during the 15th and 16th centuries. And indeed "Great Britain" did not really exist in those times.

Madie Strople: It seems your humanities teacher is a duh-brain. It happens.Great Britain as a military entity did not exist before 1707.England invaded Scotland, Ireland and France on several occasions between 1401 and 1601.
