Imperium Romanum fuit res publica antiqua cuius caput erat urbs maxima Roma et quae tempore maximae suae potestatis a Britannia usque ad Mesopotamiam extensa est. Ab Augusto Caesare imperium Romanum sic institutum est, ut res publica uni principi soli gubernanda mandaretur. Imperium Romanum tamquam totius orbis terrarum vel saltem eius orbis terrarum partis, quam totius mundi instar esse antiqui existimaverunt, dominatum obtinuit usque ad aetatem migrationum populorum et gentium, quo tempore in duas partes divisum, ubi ad occidentem solem vergebat, interiit, ubi ad orientem solem spectabat, per medium quod dicitur aevum remansit.
Ως Ρωμαϊκή Αυτοκρατορία νοείται το κράτος των αρχαίων Ρωμαίων (imperium), μετεξέλιξη της Ρωμαϊκής Δημοκρατίας όταν και οι περισσότερες εξουσίες συγκεντρώθηκαν στα χέρια ενός ανθρώπου, του Καίσαρα ή αυτοκράτορα (imperator).Το κράτος που είχαν δημιουργήσει οι αρχαίοι Ρωμαίοι πέρασαν αρκετοί αιώνες μέχρι να αποκτήσει το πολίτευμα της αυτοκρατορίας, με το οποίο το θυμούνται οι σημερινοί λαοί, αλλά έχει επικρατήσει να αναφερόμαστε με τον όρο ‘’Ρωμαϊκή Αυτοκρατορία’’ για όλη την περίοδο της αρχαίας ρωμαϊκής ιστορίας.
The Roman Empire (Latin: Imperium Romanum}, probably the best-known Latin expression where the word "imperium" denotes a territory, indicates the part of the world under Roman rule. From the time of Augustus to the Fall of the Western Empire, Rome dominated Western Eurasia, comprising the majority of its population. Roman expansion began long before the state was changed into an Empire and reached its zenith under emperor Trajan with the conquest of Mesopotamia and Armenia in AD 116. During this territorial peak the Roman Empire controlled approximately 5 900 000 km² (2,300,000 sq.mi.) of land surface. Rome's influence upon the culture, law, technology, arts, language, religion, government, military, and architecture of Western civilization continues to this day.
The WIKIMEDIA COMMONS Atlas of the World is an organized and commented collection of geographical, political and historical maps available at Wikimedia Commons. The main page is therefore the portal to maps and cartography on Wikimedia. That page contains links to entries by country, continent and by topic as well as general notes and references.
Every entry has an introduction section in English. If other languages are native and/or official in an entity, introductions in other languages are added in separate sections. The text of the introduction(s) is based on the content of the Wikipedia encyclopedia. For sources of the introduction see therefore the Wikipedia entries linked to. The same goes for the texts in the history sections.
Historical maps are included in the continent, country and dependency entries.
The status of various entities is disputed. See the content for the entities concerned.
The maps of former countries that are more or less continued by a present-day country or had a territory included in only one or two countries are included in the atlas of the present-day country. For example the Ottoman Empire can be found in the Atlas of Turkey.
