Hospodar or gospodar is a term of Slavonic origin, meaning "lord" or "master".
The rulers of Wallachia and Moldavia were styled hospodars in Slavic writings from the 15th century to 1866. Hospodar was used in addition to the title voivod. When writing in Romanian, the term Domn (from the Latin dominus) was used.
At the end of this period, as the title had been held by many vassals of the Ottoman Sultan, its retention was considered inconsistent with the independence of the Danubian Principalities' (formalized from Romania only in 1878 — replacing the tributary status). Hospodar was therefore discarded in favour of domnitor or, in short, domn, which continued to be the official princely title up to the proclamation of a Kingdom of Romania in 1881 (which did not include Transylvania until 1918).
Etymology and Slavic usage 
The pronunciation as hospodar of a word written as господар in many Slavonic languages which retain the Cyrillic script could be due to the influence of whether Ukrainian, where the first letter is pronounced as [ɦ] or that of Church Slavonic where it is pronounced as [ɣ].
In Ukrainian, hospodar is usually applied to the master/owner of a house or other properties and also the head of a family. The hospodar's house is called as hospoda . There also an alternative form for the head of the household - gazda which also common in Hungary. Hospod is used exclusively when referring to the Lord and has only has a slight relation to hospodar.
The title was used briefly towards the end of the Second Bulgarian Empire. In 1394-95, Ivan Shishman of Bulgaria referred to himself not as a Tsar (as traditionally), but as a gospodin of Tarnovo, and in foreign sources was styled herzog or merely called an "infidel bey". This was possibly to indicate vassalage to Bayezid I or the yielding of the imperial title to Ivan Sratsimir.
Ruthenian population of Grand Duchy of Lithuania used the term to style Grand Duke of Lithuania; in that sense it is also used in official documents (for example, Statutes of Lithuania), given that Old Belarusian was an official language in Grand Duchy.
