When thinking about
ihatei fleets it’s important to remember that while the word ‘
ihatei’ literally means second son, migration fleets doubtless include many females as well as many landless
htatei who might be first born but are not in line to inherit lands.
As an example of
ihatei numbers we can look at a clan I’ve been working up: let’s call them the
Wardens for now. I’m going to initially rely on CT sources to develop the following estimates, primarily because I almost always start with CT before looking at other systems but also because CT establishes a direct relationship between SOC and territory. These maths are going to involve several simplifying assumptions, so take them with the appropriate handful of salt.
The Wardens own a single world deep inside the Hierate. The total clan population is 186 million, which at a 3:1 sex ratio breaks into 139.5 million females and 46.5 million males. This is a respectably sized but unranked independent clan, large enough to field its own Ground and Space Forces.
The average Aslan family contains one patriarch plus 1D-1 (2.5) wives. Assume each wife produces 1D-2 (1.67) children, for a total of 4.67 children per family. Further assume each family has 1D-3 (1) additional members. The average Aslan family therefore consists of 8.675 members, which is consistent with CT
Aslan.
The Wardens population of 186 million equates to roughly 21.441 million individual households. That breaks into 21.441 million patriarchs, 53.603 million wives, 89.516 million children, and 21.441 million other members.
Based
on my calculations, the 89.516 million children include 11.483 million
htatei, 10.852 million
ihatei, and 67.182 million
atao (daughters).
If we use Classic Traveller assumptions that patriarchs with SOC 9+ (27.77%) are landowners , that implies the Wardens have 5.954 million landed households and 15.887 landless households.
Because male births are distributed unevenly, even though there is slightly more than one male child per household, 9.985 million households will not have a male heir, either because the family has no children or the children are all daughters. Of these households without heirs, 2.765 million will be landed. Let’s assume each of these landed families can be matched with one
ihatei, reducing our pool of clan
ihatei to 8.086 million.
Assume 90% of these
ihatei find gainful employment, either in the clan military, or as vassals, spiritual advisors, or as mercenaries outside the clan. That still leaves us with over 808,000
ihatei.
Let’s turn back to the 15.887 landless families. While many of these have no male heirs and are likely doomed to pass into history, 8.294 million households will have a
htatei who does not stand to inherit significant lands – and will thus be potentially interested in joining an
ihatei expedition. Again, if we assume 90% of these landless
htatei will be gainfully occupied within the clan, that still leaves more than 829,000 males with serious motivation to find and secure lands of their own.
Combining the true
ihatei with landless
htatei gives our little Wardens clan approximately 1.682 million males potentially open for conquest. Even if you use much more conservative assumptions, apply similar calcs across the entire Hierate and you could potentially have a great many land-hungry males.
