It is a national holiday in the country, commemorating the unification of Eastern Roumelia and Bulgaria in 1885. By the terms of the Treaty of Berlin, Southern Bulgaria was separated from the newly formed Bulgarian state and returned to the Ottoman Empire with partial autonomy. The Bulgarian Citizens considered the decisions of the Berlin Treaty to be unfair and started a peaceful demonstration against them. This developed over the years, with the formation of the Bulgarian Secret Central Revolutionary Committee in February 1885 to help unification. It was on 5th September 1885 the people rose in Goliamo Konare and after arresting the prefect of Plovdiv the militia advanced towards the capital. The following day the palace in Plovdiv (capital of Eastern Roumelia) was surrounded, and the two countries were unified into Bulgaria.
Celebrations are focused in Plovdiv, usually with parades and ceremonies, but other places do celebrate across the country.
