Republic of South Ossetia - Республикӕ Хуссар Ирыстон / Республика Южная Осетия

South Ossetia , officially the Republic of South Ossetia – the Free State of Alania, or the Tskhinvali Region, is a de facto sovereign state and disputed territory in the South Caucasus recognised by most countries as part of Georgia. It has a population of 53,000 people who live in an area of 3,900 km², south of the Russian Caucasus, with 30,000 living in Tskhinvali. The separatist polity, Republic of South Ossetia (or the State of Alania), is recognized as a state by Russia, Venezuela, Nicaragua, Nauru, and Syria. While Georgia lacks control over South Ossetia, the Georgian government and most members of the United Nations consider the territory part of Georgia, whose constitution designates the area as "the former autonomous district of South Ossetia", in reference to the former Soviet autonomous oblast disbanded in 1990. Georgia does not recognize the existence of South Ossetia as a political entity, and therefore its territory does not correspond to any Georgian administrative area (although Provisional Administration of South Ossetia was created by the Georgian authorities as a transitional measure leading to the settlement of South Ossetia's status), with most of the territory included into Shida Kartli region. The area is often informally referred to as the legally undefined Tskhinvali Region in both Georgia and international organisations when neutrality is deemed necessary. 

The South Ossetian Autonomous Oblast, created in 1922, declared independence from the Georgian Soviet Socialist Republic in 1991. The Georgian government responded by abolishing South Ossetia's autonomy and trying to re-establish its control over the region by force. The crisis escalation led to the 1991–92 South Ossetia War. Georgians fighting against those controlling South Ossetia occurred on two other occasions, in 2004 and 2008. The latter conflict led to the Russo–Georgian War, during which Ossetian and Russian forces gained full de facto control of the territory of the former South Ossetian Autonomous Oblast. In the wake of the 2008 war, Georgia and a significant part of the international community consider South Ossetia to be occupied by the Russian military. South Ossetia relies heavily on military, political and financial aid from Russia. South Ossetia, Transnistria, Artsakh, and Abkhazia are sometimes referred to as post-Soviet "frozen conflict" zones.

These three covers are sent directly from Tskhinval, the capital city of South Ossetia. The covers sent by David Langan, who is the first tourist visiting South Ossetia with the Tourist Visa issued by South Ossetian government. The covers sent on June 27, 2016 and I received on July 22, 2016.

Getting Stamps and letters from South Ossetia is considered as a treasure because it is very rare. I feel very lucky, my friend Elizabeth from North Ossetia travelled to South Ossetia in October 2015, the she posted these two cover from Tskhinval, the capital city of South Ossetia. I noticed one letter is sent as Registered too with their own barcode label and country code 'OS'. I tried to track this number it is working on international tracking sites ! So I deiced to put 'South Ossetia' is the list of independent countries. Even though their foreign affairs, military, post are heavily depending Russia, They do not use Russian stamps now. In Abkhazia, another break away republic with similar status.
