The Bulgarian Land Forces are the ground warfare branch of the Military of Bulgaria. The Land Forces were established in 1878, when they were composed of anti-Ottoman militia (opalchentsi) and were the only branch of the Bulgarian military. The Land Forces are administered by the Ministry of Defence, previously known as the Ministry of War during the Kingdom of Bulgaria. Since 2004, the Land Forces are in a process of continued restructuring. Under the most recent reform, brigades were reduced to regiments, while several garrisons and brigades were disbanded.
