Hi!
I'm playing around with building a few subsectors, and am wondering what are the limits for power projection for worlds and polities of different sizes. How many parsecs away would an individual world, pocket empire, or Imperium-sized entity be able to make its presence known economically and militarily? What's the minimum population size/industry concentration/tech level that a world would need to begin to form an embryonic pocket empire?
And what parts of a UWP, Interstellar astrography, or societal factors might effect the outcome the most?
There is, in history, a theory advanced by certain historians that the limits of direct central administration are 3 months to the edge; for decentralized controls, 6 months. I heard it from Dr Jacobs, but not as his belief, in History of Warfare. It does, however, correlate well to the Roman, Byzantine, Chin, French and British Empires. I do beliee he mentioned John Keegan, but I don't recall that being in
The Face Of Battle. I do recall laughing outright Keegan's assertions of the modernness of WW I
I feel democracy generally seems to have been limited to about a week; representative democracy to about 60, mixed empire to about 120 (British, French, German, Spanish, and Portuguese Empires).
Note that maximum speed of control is what matters, not common speed of travellers. That puts the jump range about 7.5 days, plus we need a half day to pass control messages on... Hans (RIP), myself, and Cryton worked all this years ago...
so hard minimum of 8 days per jump; sane rates at 8.5 days, and if the ship needs to meet a tanker/tender, 9 days.
the 10 day threshold is 1 jump. Much past one jump, direct democracy really seems unlikely to work, as that's 16 days round, plus action/voting...
Further, the fringes are likely less populous, so even if the votes are not totalled until theirs arrive back, the majority is already known from exit polls.
Representative democracy worked quite well in many US States, Canadian provinces, and Australian States (??? I don't know what the states were called before autonomy of the Commonwealth...), in many cases up to about 4 weeks round trip for single level. But the US and Dminion of Canada both had longer than that for their central governments - 2 months for Alaska during the 19th C, and about 3 or 4 weeks for the train... longer before train and telegraph.
The Roman, Qin, Aztec, Inca, and a few other empires with decentralization ran to about 60 days maximum for a normal traveler, The UK, France, Spain, Portugal, Germany, Holland, and Austria-Hungary managed empires up to 120 days of sail one way... by decentralization. That's not as big as whomever Dr. Jacobs was citing (180)... but this gives us a fourth window size
Direct demos: maybe 10 days...
Rep Demos: 30
Multi-level rep demo 60
Territorial remote governments 90 to 120 days
Peak Human Empire 180 days (UK, & Portugal but not for long,)
So, control vs travel - a well set up comm network is faster than sending a rep - simply because it takes under half a day to transfer info from a ship to another ship, but it can take a day to get refuelled and/or transferred to another ship for a passenger. So, we'll list 8 day, 9 day, 10 and 14 day jumps.
Type | Days | 8day/J | 8.5 day/j | 9day/J | 10day/j | 14j/10 |
direct demos | 10 | 1 J | 1 j | 1 J | 1 j | ---- |
Rep Demo | 30 | 3 J | 3 J | 3 j | 3 j | 2 j |
Multi-level rep demo | 60 | 7 j | 7 j | 6 J | 6 j | 4 j |
Remote sub-governments | 90 | 11 j | 10 | 10 j | 9 j | 6 j |
Peak Empire | 180 | 22 J | 21 | 20 j | 18 j | 12 |
Note: fractions dropped - because partial jumps do full 7 days, and can be 6.4 to 7.6 days...
8 day is fresh courier waiting, transfer via comms.
8.5 allows for usually meeting a tender
9 is meet the tender, refuel, and jump on.
10 is for reliable passenger service.
14 is the rulebook standard for small merchant service.
How big that means? well... that's pretty much TL based 9/10 is 1 PC, TL 11 is 2, TL 12 is 3...
TL 16 and jump 7 is a matter of which ruleset... IIRC, only T5 allows J7...
Hop uses the same numbers... but is less accurate, and so can result in up to an additional half day for
