The Allies of the Fourth World War were composed of various western and formerly American influenced countries tired of the influence wielded by the Soviet Union in world affairs, made more frustrating by the Dissolution of the United States in 1986. The sense of being rendered secondary by the Soviet Union led many of these countries to elect right-wing leaders to power in the beginning of the 21st century. After two disgruntled Confederate soldiers destroyed a Soviet base in Egypt in the wake of the Soviet Invasion of the Middle East, several nations vowed support for the Confederacy, and the war was on.

The Allies included:

The Confederate States of America, led by President Mike Huckabee

The Republic of the Middle Atlantic, led by President Bob Ehrlich

The Republic of Texas, led by President Rick Perry

The Republic of Pennsylvania, led by President Joseph Scarnati

The Republic of the American Southwest, led by President Bill Owens

The Republic of California, led by President Arnold Schwarzenegger

The Republic of Cascadia, led by President Dirk Kempthorne

The United Kingdom, led by Prime Minister Nick Griffin

France, led by President Jean-Marie Le Pen

Spain, led by President Jose Maria Aznar

Portugal, led by President Jose Pinto Coelho

Austria, led by President Jorg Haider

Italy, led by President Roberto Fiore

Greece, led by President Nikolaos Michaloliakos

Japan, led by Prime Minister Takeo Hiranuma

The Union of South Africa, led by President Frederik Willem De Klerk

In addition to the internationally recognized countries, several resistance governments set up in former Soviet territory aided in the struggle. These governments included:

The Free Republic of Germany, led by President Horst Kohler

The Greater German Reich, led by Führer Udo Voight

The Republic of Georgia, led by President Mikheil Saakashvili

The Republic of Armenia, led by President Robert Kocharyan

The Democratic Republic of Poland, led by President Lech Walesa

The Democratic Republic of Czechoslovakia, led by President Vaclav Havel

The Chechen Republic of Ichkeria, led by President Akmed Zakayev.

In addition, the unrecognized micronation, the Principality of Sealand, under Crown Prince Paddy Roy Bates sent an invasion force of about 20 men to attack the city of Schwerin, in Germany. The Sealander force aided the forces of Portugal, Spain and Pennsylvania in the attack, and captured some prisoners. Sealand was granted a limited recognition by Portugal in response, to the chagrin of the United Kingdom.
