Democratic Republic of Humanity

The Democratic Republic of Humanity is the main government of the Solar System and the Milky Way, which is centralized on the planet Earth. It was founded 14 years after the end of the Holocene climate crisis on Earth, where millions of humans were forced to migrate from harsher environments. The Republic, as its often referred to, strives to explore and colonize the known Universe, while also trying to improve and enrich everyone's lives.

History
Beginning in the year 2030, Earth endured chaotic weather, forcing millions of humans to migrate to safer places. Regions such as the Caribbean and Central America suffered powerful hurricanes, and Africa and the Middle East experienced extreme heatwaves. By 2050, about 2 billion humans were climate refugees.

As the years passed by, scientists and governments from across the world tried to discuss a solution. Early drafts to terraform the planet Mars were re-discussed so that they could be used to reverse the climate to a pre-Industrial Revolution state. This process began in 2105 and ended in 2120.

However, even though the planet's climate was restored, nations were still wary about each other. The leaders of these nations met and discussed ways to move forward, drafting a peace treaty. In 2134, they finally signed and ratified the treaty, making it official.
