United Belgian States
The United Belgian States (Dutch: Verenigde Nederlandse Staten or Verenigde Belgische Staten; French: États-Belgiques-Unis), also known as the United States of Belgium, was a short-lived confederal republic in the Southern Netherlands (modern-day Belgium) established under the Brabant Revolution. It existed from January to December 1790 as part of the unsuccessful revolt against the Habsburg Emperor, Joseph II. United Belgian States' area coincided between 1789 and 1790 with the western and central part of present-day Belgium.
