I only really know of Rome existing up to about WWI, and finally collapsing largely with the dissolution of the Holy Roman Empire in 1806. Even that, I can't exactly remember how it is tied to the Roman Empire.
The Holy Roman Empire was, in the words of Voltaire, "neither holy, nor Roman, nor an empire". Saying that the HRE represents the fall of Rome is about as correct as saying that the fall of the Ottoman Empire represents that same fall. It was a conglomeration of German kingdoms, ironically the only part of Western Europe not held by the Roman Empire besides Scotland and Ireland. The "Roman" part of the name comes from Charlemagne, the first HR Emperor, being appointed by the Roman Pope, and is largely unrelated to the historical Roman Empire.
The fall of the Western Roman Empire was in 476, and the fall of the Eastern Empire in 1453. Those two nations had a direct chronological connection to the Rome of Caesar and Augustus. How you define fall, and how you define Rome's lineage, may lead you to some other dates, but those two are the easiest to define and the least subjective.
Depends on what you mean by Roman. Depends on what you mean by Empire. Depends on what you mean by End. Depends on who's defining all of these words and deciding its date.
I do not say this jokingly. These are absolutely serious questions, the definition of which determines the answers to this question. All of which have political implications behind their reasoning.
But if we're going to be straight here, 476 is a perfectly workable date and is used (with its caveats) by almost everyone. We are also simultaneously willing to accept that this date is arbitrary, but continue its use because of convention.
This is a difficult to answer because the Roman empire in Rome fell 476 C.E under Romulus Augustulus but the Byzantine or the eastern Roman empire ends in 1453 under Constantine XI and then the argument can be made the the Russian Czars some themselves as Roman by tying them selves to the Byzantines which would bring the end of Rome to 1917 under Nicholas the second.

Huh? The First World War began in 1914. Rome still exists as a place. Not sure what you mean here?
Even that, I can't exactly remember how it is tied to the Roman Empire.
The civil law legal system, which is prevalent in much of the world that didn't come under British rule, traces its lineage directly to the Roman legal system. Obviously since then there have been many layers added onto it, but at its core it is the Code of Justinian. Not sure how to source that, kinda common knowledge. Probably the last true vestige of the Roman Empire in existence today.
