The Romans ruled thousands of cities. The Roman Empire was the 15th largest empire in history. At its greatest extent it had an area of 6,500,000 km² (2,509,664 sq. mi). It covered western Europe from the south up to the mouth of the river Rhine and central Germany, the Balkan Peninsula (south-eastern Europe) the Middle East west to Iran and north of Saudi Arabia, and North Africa.
At the height of its power in the 1st and 2nd centuries AD, the Roman Empire consisted of some 2.2 million square miles (5.7 million sq. km).
At its peak, there were somewhere between 50 and 90 million Roman citizens (about 20% of the world's population at that time!). Under the emperor Trajan, it stretched for 5 million square kilometers.As the historian Christopher Kelly has described it:Then the empire stretched from Hadrian's Wall in drizzle-soaked northern England to the sun-baked banks of the Euphrates in Syria; from the great Rhine–Danube river system, which snaked across the fertile, flat lands of Europe from the Low Countries to the Black Sea, to the rich plains of the North African coast and the luxuriant gash of the Nile Valley in Egypt. The empire completely circled the Mediterranean ... referred to by its conquerors as mare nostrum—'our sea'.
60 million people (or as much as 1/5 of the world's population) claimed citizenship of Rome and as many as 120 million people may have lived within its borders. ________________ Estimates of around 100m need to be taken with a pinch of salt. Modern estimates tend to range between 50 and 80 million for the total population.
The earliest known watch was the Melanchthon's Watch, a gold guilt brass cased, spherical, mechanical table watch--also called a Nuremberg Egg--from approximately 1530 AD. The first quartz watch to enter production was the Seiko 35 SQ Astron, which hit the shelves on December 25, 1969
