The Cradle of Mankind. Despite the wars that decimated the Solar System - and then, the Blackout - it remains the most populous world of the Solar System and the center of the human civilization. Although, oddly enough, the latter is mostly the result of said wars and the Blackout, which forced the Earth to stop its drive towards ever-increasing isolationism. Earth was also never united - instead of a single planetary government, there are 174 recognized independent countries on the planet. However only nine of those remain powerful enough to maintain a sizeable presence (and some ambitions) outside of the Earth's orbit. Surprisingly enough, they tend to cooperate together when needed, as most of the past political, economical and ecological issues have been successfuly solved. The leadership and headquarters of majority of interplanetary organizations of Mankind are traditionally placed here - there was a period where Titan played that role, but... well, not anymore.
Not much changed on that field, except for the fact that Earth was 'terraformed' with the usage of the World Forge terraforming nanites, essentially pushing back centuries of air pollution and global warming in the span of less than two decades. This has been a part of a larger project of restoring Earth to more liveable status, which also included cleaning oceans and restoring the damages to the terran ecosphere. Many species were lost and many places were decimated (both by the past wars and the climate change), but Mankind has persevered and, eventually, triumphed. Even the orbit was cleaned of debris dating to earlier stages of human space expansion.
It should be noted that Earth managed to exhaust most of its natural resources. Today Earth is mostly an agricultural world (with numerous space elevators making its diverse foodstuff a luxury goods - but affordable, at least in some places - throughout the Solar System. It also forces the terran governments to rely on asteroid mining to supply its industry (which is also notably underdeveloped when one tries to measure it per population number).
Earth was - and still is - the cradle of Mankind. However, the last few centuries weren't easy for it. Starting from the Days of Fire (the period of planet-wide chaos caused by the eruption of the Yellowstone Supervolcano), Earth spend those years getting hit by numerous disasters (natural or not) and multiple devastating wars (including the Third and Fourth World/Terran War). The Fourth World War was especially horrible, with no clear victor - instead, almost all participating countries collapsed to a various degree due to their economies and populations no longer able to sustain the war effort. It wasn't the last war on Earth. But eventually, they somehow ended. Earth grew increasingly isolationist during the period of the Solar Commonwealth. Partially because the colonists saw themselves as better than the terrans (due to Terra continuously waging their petty wars while they were pushing the boundaries of Mankind in peace and growing prosperity). The Commonwealth's leadership has eventually relocated to the Titan, something that was met with some rather mixed feelings on Earth. Eventually, Earth managed to fight through the most of its political issues (being thoroughly tired of wars has greatly helped) and has focused on restoring its climate and ecology. In an ironic twist, it was the colonies that began to be involved in numerous devastatic conflicts, ones that Earth wanted to have no part in. As a result, it slept through most of the Genetic Wars. Attempts to actually drag it into the war resulted in the brief Secession War, during which the tensions between the terran governments and the Solar Commonwealth ended with open hostilities. Earth has de facto seceed from the Solar Commonwealth, although only temporarily. It has rejoined it during the Transhuman Wars. With Titan mostly destroyed (together with the Solar Commonwealth's leadership that survived the Transhuman Wars), Earth was thrusted into the spotlight once again, despite being divided between several governments (and lacking any type of central government). Today it is the capital of the Solar System again, although a highly reluctant one.
