For centuries, there has been a bitter feud between the humans of Deutschland and the horses of Saddle Arabia. While the humans became allies with the dragon lands for their gunpowder, the Saddle Arabians sided with the pony kingdom- Equestria. Opting to stay out of the fighting, the princesses decided on aiding the Saddle Arabians with supply shipments; while the dragons also sent supplies to the humans. This shook the relationship between Deutschland and Equestria, however it was eventually reconnected. It was even stronger than before with tourism and immigrants from both kingdoms
200 years before Luna's return, Princess Celestia was in a panic as the cities of Manedleton, Capall, and Chapaillíní wanted to break away from Equestria. Princess Celestia, fearing a civil war, decided to send in the royal guard to calm the uprising, but was met with more resistance. For three months, several small skirmishes were scattered throughout the area. Most famously was the battle of sourdough hill where the guard launched a massive artillery strike on the rebel position in attempts to stop the rebellion. More royal guard companies were sent in, most of the ponies left. They had packed up and left, and headed to Deutschland; where they were welcomed with open arms. From there, they created the first Pony Brigade-An entire brigade of pony volunteers.
Around the same time as the Pony Uprising, the leaders of Deutschland and Saddle Arabia had been making great attempts in ending the hostilities. They had set up numerous treaties and trade deals. Ultimately, the current Sultan of Saddle decided that Saddle Arabia has had enough of Deutschland's industrialism influence and ends the treaties, secretly sending thousands of troops to the border; calling it "The Necessary Crusade" for his country.

if you mean by humanoid the ponies are actually human people. no they are the anthro ponies of half human half pony
I like that Deautchland soldiers wear Pickelhauben, they're a personal favorite
Interesting concept you have there. Out of curiosity, are you learning Irish? Cuz I'm sure Capall and Chapaillíní are both Irish for horse and pony.

No I'm American. I just decided to name those two cities that because that's supposed to be the local culture
I am very confused by these choices. I would have imagined, at lest for the equestrians, a lot of magical tech or flat out magic equipment over human tech. I mean I suppose I can get the Saddle Arabians mimicking the humans due to the lack of unicorns, but since they are getting aid mainly from the Equestrians shouldn't they be more reliant on magic as well? Eh, just my 2 cents.

When I was writing I had put that to thought. The way I saw it was that the humans are generally going to have the more advanced tech and science.
The ponies even though they have magic, they will still need weapons, since they can't rely solely on unicorns everywhere, Plus a strain on unicorn stamina. Where the equestrians will excell at is air superiority, due to pegasi and air ships. Also medical healing, being they can just use magic to treat battlefield wounds.
On the human side since they can't uses magic, they have to use science to treat wounds. Meaning recovery is slow however the doctors have a better understanding of what they are doing.
