That is the revised and Parliamentary perspective as put forth in Whig history a form of scholasticism based upon total opposition to the Stuart dynasty and represented by the wealthy and elitist aristocracy  Its not my POV it is the international viewpoint  When referring to the royal dominion of the Stuarts as shown on atlases and maps they consider it Great Britain because of facts  You are making a mountain out of a molehill  Just because the regime changes may have shifted the definition of the United Kingdom since the Jacobean era doesnt mean that the royal domain was somehow different  They remained the same lands as inherited by the Stewart and Tudor houses  Dont let the Whigs confuse you
