The Rothurien Kingdom

The largest of the Four Dwarven Kingdoms, this kingdom is known for their wealth and politics. Due to their shrewd mindset, they became a notable and powerful group that is not taken lightly. While they did join the Eranor Empire in the latter years, they were the only group that officially joined as a protectorate until the Fall of the Eranor Empire. Since then, Rothurien Kingdom was strong enough to control their lands with absolute authority and thwarted any attempts of non-Dwarven settlements into their area.

Diplomatic Relations with other Nations
Ever since the first encounter with the humans, the Dwarves regarded with the humans to somewhat caution. Over the years they learned that while few of the humans can be trusted, there are some who offsets the balance of perspective. Since the Rise and Fall of the Heldrath Empire, the Dwarves of Rothurien were wary of the humans who hails from those regions knowing that the empire's foundation stood on much blood and betrayal.

Along with the cautious truce between the humans, the dwarves are equally cautious of their elven neighbors. They have been known to have various conflicts usually involving border disputes with the elves, but despite some losses in skirmishes, they show a certain degree of respect to them, even if they do not openly show that respect.

The Halflings of Southmarch who lives on their southern border have always had a positive relationship. There rarely have been much conflict between the two and there have been times when the two fought side by side. While contact between the two decreased during the Third Age, there have been some effort to reestablish contact with one another.

With the other Dwarves, the Rothurien Dwarves regards themselves as the elite and the upper class. They perceive the Dwarves of Norgoth as warmongering barbarians, the Dwarves of Vorn as peasant stock, and the Dwarves of Stormpeak as a tight bunch of traditionalists. Despite that, they are willing to honor the call for aid should any of the Dwarves call upon them.

The New Capital
In 935 BHE, the Dwarves formed a federation in response to the elves forming the Silver Empire. Being the largest of the four Dwarven Kingdoms during the time of the formation and being in a strategic position, the capital of the Rothurien Kingdom became the default capital for the federation.
