Tsarina or tsaritsa is the title of a female autocratic ruler (monarch) of Bulgaria, Serbia or Russia, or the title of a tsar's wife. The English spelling is derived from the German czarin or zarin, in the same way as the French tsarine / czarine, and the Spanish and Italian czarina / zarina. (A tsar's daughter is a tsarevna.)
A queen consort is the wife of a reigning king, and usually shares her spouse's social rank and status. She holds the feminine equivalent of the king's monarchical titles and may be crowned and anointed, but historically she does not formally share the king's political and military powers, unless on occasion acting as regent.
The Principality of Achaea or Principality of Morea was one of the vassal states of the Latin Empire, which replaced the Byzantine Empire after the capture of Constantinople during the Fourth Crusade. It became a vassal of the Kingdom of Thessalonica, along with the Duchy of Athens, until Thessalonica was captured by Theodore, the despot of Epirus, in 1224. After this, Achaea became for a while the dominant power in Greece.
A queen dowager or dowager queen is a title or status generally held by the widow of a king. In the case of the widow of an emperor, the title of empress dowager is used. Its full meaning is clear from the two words from which it is composed: queen indicates someone who served as queen consort, while dowager indicates a woman who continues to hold the title from her deceased husband. A queen mother is a former queen consort, often a dowager queen, who is the mother of the reigning monarch.
A lady-in-waiting or court lady is a female personal assistant at a court, attending on a royal woman or a high-ranking noblewoman. Historically, in Europe, a lady-in-waiting was often a noblewoman but of lower rank than the woman to whom she attended. Although she may either have received a retainer or may not have received compensation for the service she rendered, a lady-in-waiting was considered more of a secretary, courtier, or companion to her mistress than a servant.
A queen regnant is a female monarch, equivalent in rank and title to a king, who reigns suo jure over a realm known as a "kingdom"; as opposed to a queen consort, who is the wife of a reigning king; or a queen regent, who is the guardian of a child monarch and rules pro tempore in the child's stead, be it de jure in sharing power or de facto in ruling alone. She is sometimes called a woman king. A princess regnant is a female monarch who reigns suo jure over a "principality"; an empress regnant is a female monarch who reigns suo jure over an "empire".

Suo jure is a Latin phrase, used in English to mean 'in his own right' or 'in her own right'. In most nobility-related contexts, it means 'in her own right', since in those situations the phrase is normally used of women; in practice, especially in England, a man rarely derives any style or title from his wife although this is seen in other countries when a woman is the last heir of her line. It can be used for a male when such male was initially a 'co-lord' with his father or other family member and upon the death of such family member became the sole ruler or holder of the title "in his own right" (alone).
Marie of Bourbon was the sovereign baroness of Vostitsa in 1359-1370. She was the empress consort of and the Princess of Achaea of by marriage to Robert of Taranto, Prince of Achaea and titular Latin Emperor of Constantinople.
The Latin Emperor was the ruler of the Latin Empire, the historiographical convention for the Crusader realm, established in Constantinople after the Fourth Crusade (1204) and lasting until the city was recovered by the Byzantine Greeks in 1261. Its name derives from its Catholic and Western European ("Latin") nature. The empire, whose official name was Imperium Romaniae, claimed the direct heritage of the Eastern Roman Empire, which had most of its lands taken and partitioned by the crusaders. This claim however was disputed by the Byzantine Greek successor states, the Empire of Nicaea, the Empire of Trebizond and the Despotate of Epirus. Out of these three, the Nicaeans succeeded in displacing the Latin emperors in 1261 and restored the Byzantine Empire.
