Pre-WWI Kingdom of Romania.
When Romania was formed by the union of Wallachia and Moldavia, Jewish residents did not become citizens of the new state.
Prince Alexandru Ioan Cuza announced in 1865 a project which would lead to the "gradual emancipation of the people of Mosaic faith", however, all the plans were canceled as Cuza was deposed the following year.
After Cuza was deposed, Article 7 of the 1866 Constitution of Romania did not allow non-Christians to become citizens of the United Principalities of Romania, so Jews could not become citizens unless they converted to Christianity.
The change in outlook can be explained by the weakening of the liberalism which led to the 1848 Revolution and its replacement with nationalism.
As a result of the Russo-Turkish War (1877–1878), Romania gained its independence and at the Congress of Berlin of 1878, the nations of Europe recognized it, with the condition of making all citizens, regardless of ethnic origin or religious beliefs, equal under law.
In 1879, the Parliament of Romania grudgingly removed the constitution article which barred Jews from becoming citizens.
However naturalization was still a cumbersome process requiring a personal petition and the approval of the Parliament on individual cases.
The result was that very few Jews were naturalized: between 1866 and 1904, only 2000 people of Jewish faith were naturalized, of which 888 were granted citizenship for their participation in the Russo-Turkish War. 
The original Romanian term, ""România Mare"," or "Great Romania", carried irredentist overtones, used in the sense of "re-integration" of the territories that shared Romanian language and culture.
The term became more common after the Treaty of Versailles, when the attachment of Transylvania to the Kingdom of Romania occurred as a result of the Treaty of Trianon.
Thus, the Kingdom of Romania under King Ferdinand I came to include all provinces with an ethnic Romanian majority, by comparison with the Romanian Old Kingdom under King Carol I, which did not include the provinces of Transylvania, Bessarabia and Bukovina.
An alternative name for "România Mare", coined at the same time, was in the Romanian language "România Întregită" (roughly translated in English as "Romania Made Whole," or "Entire Romania").
"România Mare" was seen (and is also now seen by the great majority of the Romanian people, both at home and abroad) as the 'true', "whole" Romanian state, or, as Tom Gallagher states, the "Holy Grail of Romanian nationalism".
When used in a political context it has an irredentist connotation, mainly concerning the territories that were ruled by Romania in the interwar period, that are now part of Ukraine, the Republic of Moldova or Bulgaria.  
The King of the Romanians (Romanian: "Regele Românilor"), was the sovereign ruler of the Kingdom of Romania from 1881 until 1947, when Romania was proclaimed a People's Republic following Michael I's forced abdication. 
György Harag (June 4, 1925, Marghita, Kingdom of Romania – July 7, 1985, Târgu Mureș, Socialist Republic of Romania) was a Hungarian director and actor from Transylvania, Romania. 
Trăiască Regele ("Long live the King") was the national anthem of the Principality of Romania and later Kingdom of Romania between 1866 and 1947.
The music was composed in 1862 by Eduard Hübsch, an army captain who later became the chief of the music department of the Minister of War.
The lyrics were written by the Romanian poet Vasile Alecsandri in 1881, when Romania became a Kingdom.
