Brasilia
Brasilia is an old city with a long line of foundings and fallings. It was first founded at some point in 2018 and abandoned thereafter for unrecorded reasons. At the start of January, 2019, the city was refounded by BlackQuartz, Emperor of Imperial Brazil. The city became the nation's capital and seat of government. It became also the largest city in the nation (both in size and population). Towards the end of the Second Brazilian Civil War, the battle of Brasilia-Belo Horizonte played out, involving Brasilia (as the name spoils). After the core fighting of the war, the nation and it's cities slowly fell till Brasilia was all that remained of Imperial Brazil. BlackQuartz went inactive and the city fell on the 17th of October, 2020.
Xingu claimed the ruins less than two days later. Liao_Niwa became Mayor. Less than two weeks later, the Pindorama Union became the Brazilian Republic and the city transferred to GetFrosted, who left EMC, and as a result, Brazil. Inevitably, the city fell and was reclaimed by South America on the 23rd of December 2020. South America tried to rebuild it but abandoned the city.
