Government of Romania in the context of "Ministry of National Defense (Romania)"

The Kingdom of Romania remained neutral throughout the first two years of World War I. They eventually entered the conflict on the side of the Entente from 27 August 1916 until insurmountable pressure from Central Powers - which had occupied two thirds of the country - led to an armistice being signed on 9 December 1917. Six months later, a crippling peace treaty was imposed on Romania, which the government ratified. King Ferdinand I refused to promulgate the treaty, hoping for an Allied victory on the Western Front. As the Central Power war efforts collapsed, Romania re-entered the war on 10 November 1918.

Romania was still a burgeoning state with great territorial ambitions at the onset of the war. It had achieved its independence following the Russo-Turkish War of 1877–1878, although millions of ethnic Romanians continued to reside outside the new nation's borders, particularly in Transylvania and Bessarabia, which were part of Austria-Hungary and Russia respectively. The Romanian monarchy, which was formed by members of the Hohenzollern dynasty, who were of Germanic origin, was sympathetic towards the cause of the Central Powers. The nation's political elite and the majority of the public favoured the Entente, as joining them would allow Romania to take Transylvania from Austria-Hungary, a region rich with natural resources and inhabited by a Romanian majority. Because of this social division and the general feeling that Romania still wasn't fully prepared for a war against a great power, the Romanians initially opted for neutrality.

A total of 41 counties (Romanian: județe), along with the municipality of Bucharest, constitute the official administrative divisions of Romania. They represent the country's NUTS-3 (Nomenclature of Territorial Units for Statistics – Level 3) statistical subdivisions within the European Union and each of them serves as the local level of government within its borders. Most counties are named after a major river, while some are named after notable cities within them, such as the county seat.

The earliest organization into județe of the Principalities of Wallachia and Moldavia (where they were termed ținuturi) dates back to at least the late 14th century. For most of the time since modern Romania was formed in 1859, the administrative division system has been similar to that of the French departments. The system has since changed several times and the number of counties has varied over time, from the 71 județe that existed before World War II to only 39 after 1968. The current format has largely been in place since 1968 as only small changes have been made since then, the last of which was in 1997.

A județ (pronounced [ʒuˈdets], plural județe [ʒuˈdetse]) is an administrative division in Romania, and was also used from 1940 to 1947 in the Moldavian Soviet Socialist Republic and from 1998 to 2003 in Moldova.

There are 41 județe in Romania, divided into municipii (municipalities), orașe (cities) and comune (communes). Each județ has a county seat (reședință de județ) which serves as its administrative capital; this designation usually belongs to the largest and most developed city in the respective county. The central government is represented by one prefect in every județ.

The prime minister of Romania (Romanian: Prim-ministrul României), officially the prime minister of the Government of Romania (Romanian: Prim-ministrul Guvernului României), is the head of the Government of Romania. Initially, the office was styled President of the Council of Ministers (Romanian: Președintele Consiliului de Miniștri), when the term "Government" included more than the Cabinet, and the Cabinet was called the Council of Ministers (Romanian: Consiliul de Miniștri). The title was officially changed to Prime Minister by the 1965 Constitution of Romania during the communist regime.

The Székelys (pronounced [ˈseːkɛj], Székely runes: 𐳥𐳋𐳓𐳉𐳗‎), also referred to as Szeklers, are a Hungarian subgroup living mostly in the Székely Land in Romania. Of the Székelys of Bukovina, some are still living in their native villages in Suceava County in Bukovina, but a significant number of their descendants is currently living in Tolna and Baranya counties in Hungary and certain districts of Vojvodina in Serbia.

In the Middle Ages, the Székelys played a role in the defense of the Kingdom of Hungary against the Ottomans in their posture as guards of the eastern border. With the Treaty of Trianon of 1920, Transylvania (including the Székely Land) became part of Romania, and the Székely population was a target of Romanianization efforts. In 1952, during the communist rule of Romania, the former counties with the highest concentration of Székely population – Mureș, Odorhei, Ciuc, and Trei Scaune – were legally designated as the Magyar Autonomous Region. It was superseded in 1960 by the Mureș-Magyar Autonomous Region, itself divided in 1968 into two non-autonomous counties, Harghita and Mureș. In post-Cold War Romania, where the Székelys form roughly half of the ethnic Hungarian population, members of the group have been among the most vocal of Hungarians seeking an autonomous Székely region in Transylvania. They were estimated to number about 860,000 in the 1970s and are officially recognized as a distinct minority group by the Romanian government.

The Romanian Ministry of Foreign Affairs (Romanian: Ministerul Afacerilor Externe) is the ministry responsible for external affairs of the Romanian Government. The current foreign minister is Oana Țoiu.

The Deputy Prime Minister of Romania (Romanian: Vice prim ministru României), officially the Deputy Prime Minister of the Government of Romania (Romanian: Vice prim ministru Guvernului României), is a minister in the Government of Romania. It is considered a non-portfolio role.
