In terms of the area of control established by communications, unquestionably the British Empire - with telegraph connections to Australia established in 1871, Britain had enormous swaths of the globe - from Tikitiki on the North Island of New Zealand all the way west to Beaver Creek in the Yukon, with stops for the Indian subcontinent and an enormous chunk ...

It took about two weeks. By 1890 postal unions had been formed allowing mail to transit around the world to most places. The domestic rate in the US was 2¢ per ounce. For a first class letter weighing 1/2 ounce or less to Britain the union cost would be an additional 5¢. Thus, the total cost was 7¢ for a first class letter. Here are the rates from 1890, ...

A rough estimate of the time is as follows: the distance from London to NY is approximately 3000 (nautical) miles. The Blue Riband prize was awarded to passenger liners which showed the average speed of about 15 knots, (20 knots was the world record in 1889), so I suppose it is safe to assume that an average ship at that time could cross with the average ...

It is a strange way, of course to measure the SIZE of an empire in terms of the TIME of travel from end to end; at different times different means of transportation were available, and it also depended on the season. But if one accepts this strange criterion, perhaps Russian empire in the early 19s century is hard to beat: it stretched from Alaska and ...

First of all, your assumption that slaves in Rome addressed their master as "domine" is not true. The language used in the household was completely different than the "silver" Latin you read in Cicero or Seneca. Vernacular Latin had large amounts of Greek slang in it and the lower in the class the person, the more slangy it got. Words like kurios and ...

The answer for land empires may have been the Mongol Empire due to its enormous size. (After seeing @RISwampYankee's answer, he probably has the correct answer over all.) However, the Mongols were not only incredible horsemen but also had a very efficient postal system called the Yam. According to National Geographic: At the postal route's zenith, a ...

The object in question is a blank spool of recording tape for a multiplex photographic recording system. Such systems were commonly used not only at Sayville, but at all transatlantic radio receiving stations. The way the systems worked is that a photographically sensitive tape was fed into a galvanometrically modulated exposer and then immediately ...

Tom Reiss, in his biography of Kurban Said, provided an example of this. Central Asian nomads would leave caches of bread in the desert; how much was eaten would communicate to other passing nomads information about who had travelled through, etc. Edit: It's page 58-59. Some points to consider: It only says that Nussimbaum (said's real name) speculated ...

There is little doubt that until 19s century most people could communicate and socialize only with those in close proximity to them. Travel was slow, expensive and dangerous. But regular mail service was also not available to everyone in most places, most of the time. When we read in the history of mail that such and such emperor "established mail service", ...

Here's an excerpt from Kadin2048's answer to this question at ask.metafilter.com, making a reasonable summation if we consider the wire recording (Wiki) techniques that were known at the time: What I think is more likely, is that the tape was just colored in dark and light patches or stripes, and that it was decoded manually. As the tape went through the ...

Besides official or secret agent movement of news and papers, it was routine for soldiers on picket duty to swap newspapers and reading material along with coffee and tobacco when armies were in contact. The desire for different reading material was very strong.

As soon as the death was published in northern newspapers it would have become available to the south. For an important event, like Lincoln's assassination, a man would have used a horse and carried a newspaper right to Richmond, which is about 100 miles away from Washington DC, where the assassination occurred. Since the first reports were published on the ...
