Sovereign entities are often called states and countries interchangeably. But "country" is a much older term, citizenship simply came into existence in international law after the UK but before the EU. England indeed sadly has no autonomy, but throughout history countries still exist even when occupied, it's not about politicians and power, it's about people, land and nations. English is a real majority nationality and culture in the well defined country of England, German is the majority nationality in Lower Saxony. Aruba is a country, not a territory unlike the term for most other imperial remnants. Countries can exist outside the UN, see Taiwan and pre-1945 nations for example, and the visa issue doesn't apply for French wishing to visit Northern Ireland from Ireland, so visa boundaries certainly don't define the UK. Hope that helps.
People generally don't need a visa to travel from the Republic of Ireland to Northern Ireland because - pre-dating and quite separately from the EEC, EU, etc - the UK (ie England, Scotland, Wales, N Ireland) together with the RoI, plus the Isle of Man and all the Channel Islands [which themselves, by the way, are made up of more than one separate legal entity] are in one Common Travel Area, whereby people have the right to move freely within and between any of them, mostly irrespective of which of them they have citizenship of. This was reinforced - especially in terms of the border between the RoI and NI - by the "Good Friday Agreement" more than 20 years ago, which helped resolve (albeit not fully) the conflict in Northern Ireland.
Similarly, people with visa-free travel to one part of the CTA will generally have visa-free travel to the rest. (I think there are some exceptions relating to the IoM and CI in terms of how long you can stay and so on.) There's a scheme whereby people from some countries who do need a visa for Ireland and the UK can get one visa which is valid for both (like a mini version of the Schengen Zone countries), though they wouldn't need to show it travelling between the RoI and NI. There can be identity checks between either part of Ireland and GB (ie the parts of the UK other than NI), but for citizens of the Common Travel Area they can be something less than a normal full passport. If you're a citizen of anywhere else, then you can be - though you aren't always - required to show a passport when entering GB from either part of Ireland.
