Which modern day countries did the Roman Empire cover? [Map]

Roman Empire Modern Countries Map

Above is the map of the fullest possible extent of the empire, including eventually abandoned German territories up to the Elbe river, the temporary Dacian, as well as the Armenian and Persian territories of emperor Trajan and the advance to the Antonine Wall in Scotland under emperor Antoninus. The boundaries drawn in black are an attempt at showing the current day national boundaries in relation to the empire.

Below you find a list of nations which were either definitely part of the Roman empire, or possibly so. Also included are some countries which had some frontline outposts in them.

The principal modern day nations of the Roman Empire are in bold print. Other countries which only saw some form of Roman occupation, or of whose effective membership of the empire I am unsure of, are listed in normal print.

Albania
Algeria
Andorra
ArmeniaWith the annexation of the ancient kingdom of Armenia by emperor Trajan all of modern day Armenia will have become part of the empire.
Austria
AzerbaijanWith the annexation of the ancient kingdom of Armenia by emperor Trajan part, if not all, of modern day Azerbaijan will have become part of the empire.
Belgium
Bosnia-Herzegovina
Bulgaria
Croatia
Cyprus
Czech RepublicThe initial conquest of German territories up to the river Elbe under emperor Augustus may well have included a small part of the Czech Republic. Also the campaigns of emperor Marcus Aurelius most likely conquered a considerable amount of Czech territory, though these gains were abandoned by his son Commodus without ever being recognised as a province.
Egypt
France
FYR Macedonia
GeorgiaWith the annexation of the ancient kingdom of Armenia by emperor Trajan part, if not all, of modern day Georgia may have become part of the empire.
Germany
Greece
Hungary
Iraq
Israel

KuwaitIf any part of northern Kuwait was part of the short-lived province of Mesopotamia, created by emperor Trajan, I am unsure. Though it may well have done.
Lebanon
Liechtenstein
Luxembourg
Lybia
Malta
Monaco
Morocco
Netherlands
PalestineNot an internationally recognized nation, It would have been part of the Roman province of Judaea.
Portugal
Romania
San Marino
Saudi ArabiaWith emperor Trajan’s annexation of part of the kingdom of Nabatea as the Roman province of Arabia Petraea, a small part of the Red Sea coast of Saudia Arabia became part of the Roman empire.
SlovakiaSlovakia was home to several forward positions of the Roman frontier system. Also the campaigns of emperor Marcus Aurelius most likely conquered considerable parts of Slovakia, though they were abandoned by his son Commodus without ever being recognised as a province.
Slovenia
Spain
SudanTo what extent the Roman province of Aegyptus extended into Sudan I am unsure of. Though it must have extended some way into this country to border on the kingdom of Nubia.
Switzerland
Syria
Tunisia
Turkey
United Kingdom
Vatican City
Yugoslavia
