Гадячский договор
In the aftermath of the November Uprising in 1831, there was an attempt to recreate the Treaty of Hadiach, to form a Polish–Lithuanian–Ruthenian Commonwealth to throw off the partitions of Poland. It was then that the coat of arms of the proposed Commonwealth was created. The planned convention in Hadiach was declared illegal by the Russians, who stationed close to 2,000 soldiers there to ensure that no meetings or demonstrations take place and blocked passage through nearby bridges. Despite these precautions, a mass and a celebration involving 15–20,000 people and over 200 priests (both Catholic and Orthodox) took place near Hadiach.
