Each player in The Republic of Mylantium takes the part of a Faction—a group sharing certain interests or affinities, be they economic, religious, cultural, or social. Because these interests are very sensitive to government action, these groups have organized themselves on a national scale to influence the government.

The interests of each group partially overlap and partially conflict with the interests of the other groups; thus, there is potential for both competition and cooperation among players. That player will do best who identifies areas of common cause with fellow players and negotiates successful alliances with them. Such alliances, all should be aware, are liable to be short-term: once the Factions in a coalition have realized those goals they share in common, they will likely to fall into competition with each other.

Here is a brief rundown of each Faction in the game; click on the links to view a Faction's webpage:

Plutocrats: Money interests, including bankers, merchants, financiers, and those who depend upon trade. Hence, these oppose items that hamper trade (like tariffs) and support those that foster it (like naval units to protect trading interests). They generally favor low taxes and low government spending, unless they have a financial interest in that spending (through the Federal Bank of Mylantium).

Robber Barons: Industrial capitalists who make their money through the manufacture of goods, mostly for the domestic market. They favor investments in items that foster industrial development (like railroads and cities) and protective tariffs that keep prices high. They also make money off the manufacture of military hardware and so tend to support a strong military. Otherwise, they tend to favor low taxes and spending.

Grangers: The rural, mostly agricultural population. Concentrated in the inner praries of Mylantium, these citizens do not ask for much in the way of financial success and are mostly content if left alone. But they also believe that true virtue can only be cultivated in the countryside and greatly resent the rise of metropolitan population centers. The presence of hostile aborigines also means that they favor the presence of strong cavalry units to deter and punish raids. They also dislike tariffs, as they raise the price of goods.

Snake Handlers: This peace-loving cult is the dominant religious group in the Republic. It is highly evangelical, however, and seeks to spread its message of peace, brotherhood and the adoration of venomous serpents as widely as possible. It has a strong hold on the education system and dominates university life.

Rednecks: A significant portion of the populace of Avalon was and continues to be hostile to the Federal government. But instead of taking up arms they have turned their resistance into a struggle to dominate the federal union through constitutional means. The goal, apparently, is to turn Mylantium into a kind of Greater Avalon, and the Rednecks seek to tighten their hold on the Republic by developing the industrial, economic, and political resources of Avalon.

Brass Hats: The promise of a permanent military force has engendered the rise of a military elite in the Republic's armed forces. They receive support not only in the armed forces themselves but also from those military contractors whose economic health depends upon a steady stream of defense orders.

Proles: The urban workers of the Republic are engaged in a struggle with the Robber Barons over the fruits of Mylantium's industrial success. Every penny in wages is deducted from the Robber Baron's profits (or, alternately, every penny in dividends is one denied to the industrial employees), and one of the sharpest sources of disagreement is over the enactment of a Minimum Wage to distribute these wages more fairly. Apart from that, though, both Proles and Robber Barons have a great interest in seeing Mylantine industry grow and flourish while being protected from foreign competition.

Bureaucrats: These represent the white-collar workers in the government and elite institutions that profit from legislative activity and the administration of a large centralized government. They very much favor any program, tax, or tariff that will increase the size, scope, and power of the government.
