Before the fateful eruption of the Yellowstone Caldera, the Commonwealth of Erie was part of the US state of Pennsylvania. Historically this area of the state was important as it provided the only major waterway system and connection for Pennsylvania.

Yellowstone Eruption

The state was affected by the raining ash and the darkness that followed. The city of Erie lost contact with Harrisburg after telegraph and phone lines collapsed from the weight of the slurry ash.

After waiting for months, nothing was heard from Harrisburg, Washington DC, or any other nearby populated area. Erie attempted to control the situation, deploying police units and National Guard regiments to guard stores, infrastructure, and other important areas.

Post Yellowstone

Unfortunately by the spring of 1937 people were sick of the rationing, lack of sunlight, and other problems that arose due to the atmospheric particles. The mayor of Erie, James Patrick Rossiter declared himself President of the Republic of Allegheny. He said there would be food for all and safety from the marauding bandits that were becoming common to the area.

This began a tyrannical 12 year rule of fear. In control of the National Guard, the President quickly seized control, crushing opposition, quashing rebellions, and only giving adequate rations to those loyal to him.


Through efforts from the military and alliances, the nation expanded quite rapidly, after 5 years it was in complete control of the entire north western part of the former state.


In November of 1948 a group of discontent citizens, National Guardsmen, and political leaders met and drafted the Constitution of the Commonwealth of Pennsylvania.

The nation at the time consisted of Erie, Warren County, Crawford County, Venango County, Mercer County, and Clarion County. The nation's name was the Republic of Allegheny

The rebels gathered rifles, shotguns, ammunition, and some heavier weaponry and hid in Armstrong County, recruiting the local lightly armed city states surrounding it to aid them.

From their stronghold, the rebels declared the Commonwealth of Armstrong and declared war on the Republic of Allegheny. The war was an uneven match at first with the republic having mustered 24,000 troops all armed with M-1 Garands, 7 M2 Light Tanks, 12 M1917 tanks, and 180 assorted improvises armored cars along with a squadron of 4 Boeing P-12's, 3 Boeing P-26's, and 1 Martin B-10.

The rebel group and the Commonwealth of Armstrong were poorly armed, mustering 25,700 troops, 1,700 had M1 Garand's, 22,500 had M1903 Springfield's, and the rest had an assortment of rifles and shotguns. This ragtag group had few armored vehicles, using one M1917 tank, and 70 assorted improvised armored cars. They had no air support.

This begin what is known as the Armstrong-Allegheny War.

Modern Day

Today the Commonwealth is a thriving nation with a strong government and economy. Much of the national infrastructure has been upgraded and repaired, along with new infrastructure to improve communication, reliability, and safety.

The government recognizes the USA as the successor state to the United States of America, but does not recognize their claim over all of the former United States.

They have good relations with surrounding nation, being allies with Canada, and often holding joint military exercise, and having a strong trade basis.


The nation is a Democratic Republic, following the same pattern of government as the state of Pennsylvania that preceded it. There is the Executive Branch, the Legislative Branch, and the Judicial Branch. The seat of government is Erie, PA. It was picked because there was already a strong city government in place, the US Supreme Court 9th Circuit of Appeals was in Erie, as well as being a port city, so ships could access it.

Executive Branch

The executive branch is the head of government. The leader is the Governor, and Lieutenant Governor. Other important members are the Secretary of State.

Legislative Branch

The legislative branch shares the powers between the Senate (Upper House), and the House of Representatives (Lower House). There are 2 elected senators per state and 1 representative per 100,000 citizens per state with each state getting at least two representatives.

In the House, the political party with the majority members gets the position, Speaker of the House. The head of the Senate is the Lieutenant governor.

Judicial Branch

The judicial branch is headed by the Supreme Court of the Commonwealth of Erie. It is headed by six judges and one head judge. Each is appointed to their position by the Senate who must get the House's approval before taking office. Each judge holds his position for ten years. Only a certain amount of cases are heard in the Supreme Court, generally dealing with lawsuits against the Commonwealth, disputed between states, or foreign aliens accused of a crime within the nation.

Each state within the Commonwealth has their own court system called the State Court of Justice, hearing more cases per year than the Supreme Court. Many of them deal with capital crimes, appeals, or advanced cases. There are tree justices per state. They are elected in by the citizens of the states every seven years.

Internally, each county has their own county courts with one to three judges who hear civil suits, and other minor offenses. They are elected in by the citizens of each county every four years.
