I am wanting to know if an empire with a continental size, lots of biomes, and a lot of diversity could survive. Might be good for the start or the middle of a story.
Basically what is in this image + Hawaii is what the empire spans in terms of area(North America + Hawaii + Iceland). That is $24,492,000$ sq km or $9,456,414.067$ sq mi. Even though I myself am more of a fan of the mile, I think it will be best to think in kilometers here since that is a nice round number.
Now lets divide this large area into biomes.
I am going to say that these are its biome percentages:
- Tundra: 10%
- Ice: 5%
- Tiaga: 10%
- Forest: 25%
- Freshwater: 20%
- Mountains: 5%
- Grasslands: 15%
- Desert: 5%
- Intertidal: 5%
Of the forest I will divide it like so:
- Temperate Deciduous: 40%
- Temperate Rainforest: 10%
- Temperate Coniferous: 20%
- Tropical Rainforest: 20%
- Tropical Deciduous: 10%
The freshwater I will divide like so:
- Lake: 40%
- River: 30%
- Wetland: 30%
The wetland divides even further into:
- Marsh: 20%
- Wet meadow: 30%
- Swamp: 50%
Wet meadow also counts as a grassland so I won't include it in the grassland subdivisions:
- Prairie: 30%
- Savannah: 30%
- Scrubland: 40%
This is high. Here are the groups of people here:
Arctic natives generally are very pale and have thicker, denser hair all over their bodies. These are adaptations to the cold and low amount of sunlight. They don't need as much clothing to survive in the arctic as the people who live in temperate or tropical climates
These people live in deserts and dry grasslands. In fact you could technically call a dry grassland like for example prairies a desert of some sort because they don't receive much annual rain. These people have adaptations against dehydration such as getting water from plants, concentrated urine, and ways of cooling off besides sweat. These people also have dark skin and very thin and sparse hair
These are people who live in forests. They climb trees better than anyone else and they have very good vision. Some can see heat, some can't, but all have evolved great night vision which is important when you are hunting for your food. These people avoid vitamin D deficiency by eating the organ meats of their prey. Some that live in deciduous or coniferous forests don't have to eat organ meats as often because the sun shines through the canopy of the forest. These people have a range of skin colors, hair thicknesses, and hair densities.
These people live being surrounded by water. They know that some big reptiles live in those waters and they also have a stronger immune system because there are more pathogens that could potentially cause infections. They are naturally more dark skinned to blend in with their surroundings. They too have thick, dense, hair but for a totally different reason from that of the arctic natives. Arctic natives have thick, dense hair for warmth whereas wetlanders have thick, dense hair as a waterproof coat. Even the soles of their feet have thick, dense hair.
And of course culture varies throughout the proposed empire so there is even more diversity than these biological adaptations would suggest and there is also technology and urbanization to take into consideration.
The politics is more democratic as to be fair to everyone. I actually found out yesterday that democratic empires are possible(the EU would fit into this category of democratic empire if it was considered an empire). There is 1 person who rules over the entire area but that 1 person takes into consideration the opinions of everyone when new laws are being made, thus democratic.
If some people find a law to be unfair to them for some reason, the ruler will make those people an exception to that law or make a new law which is more fair to everyone to replace the old law that was unfair to a certain group. There are elections for the next ruler though these are not as regular as for a president and are usually done either when the ruler is old or unhealthy. There is some precedence towards electing a family member of the ruler but of course there are times when the people think that a ruler outside of that family would be better.
Communication across such a wide distance is needed and how things are communicated depends on the distance the message has to get across. If for example a message has to get from the arctic to the tropics, the internet or satellite communication would be used. For small distances, just walking to where the message is to be received and saying what is in the message or mailing it would be enough. In between these extremes you have radio which can be used to send messages that are important a long distance, electric cars for between cities or within a city, horseback for across more sparsely populated areas, especially grasslands, and of course you have aircraft and trains which are more commonly used to send messages to someone in a desert or on permanent ice in the arctic, though an aircraft might be used to send messages to people in wetlands.
This communication over long distances is 1 of the things that makes them consider themselves 1 people even though biologically and culturally speaking they are very diverse. Another is the fact that they know they are governed by 1 person.
Of course there is the internal threat that some people within the empire might want to dissolve it but as far as external threats there aren't very many. About the only external threats they might face is resistance to expand which to be fair would not be much of a threat. I mean with the continental size of the empire it is plenty big enough without expanding.
Taking the size, biomes, diversity of people, politics, and threats in the proposed empire into consideration, is there any chance that this empire could survive?
