September Revolution (Hulstria and Gao-Soto)

The September Revolution, alternatively referred to as the Septembrist Revolution or the September Restoration, is the name generally given to the largely peaceful popular uprising in the years 3411-3416 led by the 15th of September Movement (from which it took its name) which ended the fascist regime of the Imperial Socialist Party in Hulstria and Gao-Soto and restored democracy under a constitutional dual monarchy known as the United Imperial Crownlands of Hulstria and Gao-Soto. The resulting democratic regime was strongly associated with the ideological and constitutional principles of Septembrism, including constitutionalism, moderatism, democracy and social cohesion between the two constituent Empires. The revolution, its heritage and its values are commemorated annually across the Crownlands on the 15th of September, known as September Day, which has grown to become the principal national holiday of Hulstria and Gao-Soto in the post-Septembrist era.

Prominent Septembrist leaders included Thomas Michels, honoured as the Father of the Constitution and the first Governor-General of the United Imperial Crownlands, chief diplomat Sebastian Goddestreu, Patriarchal Cardinal Medgar Haas and then-Crown Prince Okatori Kurosawa. Additionally, many of the Crownlands' post-Septembrist leaders from across the political spectrum have played roles in the Revolution, including AF leader Matthias Reiniger and Staatsministerin Hosianne von Metten.

The significance and impact of the September Revolution are oft-remarked upon by scholars of Hulstrian and Gao-Showan history as a focal point in the nation's history. The joint struggle for the restoration of democracy and the dual monarchy, in particular, is credited with bringing Hulstrians and Gao-Showans closer to eachother than at any point before in the history of the Crownlands, and thus largely to have ended the emnity between the two groups that existed since the years of apartheid. Historians also note the differences between post-Septembrist Hulstria and Gao-Soto, which is marked by full parliamentary democratic structures of government, and the Greater Hulstria era, which maintained some of the aristocratic features of the Hulstrian empire within the democratic framework. As such, the September Revolution has increasingly been ascribed the status of a new "founding myth" for the Crownlands.
