A prince is a male ruler or a male member of a monarch's or former monarch's family. Prince is also a title of nobility, often hereditary, in some European states. The female equivalent is a princess. The English word derives, via the French word prince, from the Latin noun prīnceps, from primus (first) and caput (head), meaning "the first, foremost, the chief, most distinguished, noble ruler, prince".
A marquess is a nobleman of high hereditary rank in various European peerages and in those of some of their former colonies. The German-language equivalent is Markgraf (margrave). A woman with the rank of a marquess or the wife of a marquess is a marchioness or marquise. These titles are also used to translate equivalent Asian styles, as in Imperial China and Imperial Japan.
Duke is a male title either of a monarch ruling over a duchy, or of a member of royalty, or nobility. As rulers, dukes are ranked below emperors, kings, grand princes, grand dukes, and sovereign princes. As royalty or nobility, they are ranked below princes and grand dukes. The title comes from French duc, itself from the Latin dux, 'leader', a term used in republican Rome to refer to a military commander without an official rank, and later coming to mean the leading military commander of a province. In most countries, the word duchess is the female equivalent.
Grand duke is a European hereditary title, used either by certain monarchs or by members of certain monarchs' families. In status, a grand duke traditionally ranks in order of precedence below an emperor, king, grand prince, archduke, or prince-archbishop, and above a sovereign prince or sovereign duke. The title is used in some current and former independent monarchies in Europe, particularly:
A grand duchy is a country or territory whose official head of state or ruler is a monarch bearing the title of grand duke or grand duchess.
Margrave was originally the medieval title for the military commander assigned to maintain the defence of one of the border provinces of the Holy Roman Empire or a kingdom. That position became hereditary in certain feudal families in the Empire and the title came to be borne by rulers of some Imperial principalities until the abolition of the Empire in 1806. Thereafter, those domains were absorbed into larger realms or the titleholders adopted titles indicative of full sovereignty.
A title is one or more words used before or after a person's name, in certain contexts. It may signify either generation, an official position, or a professional or academic qualification. In some languages, titles may be inserted between the first and last name. Some titles are hereditary.

Graf is a historical title of the German nobility and later also of the Russian nobility, usually translated as "count". Considered to be intermediate among noble ranks, the title is often treated as equivalent to the British title of "earl".
Holstein-Gottorp is the historiographical name, as well as contemporary shorthand name, for the parts of the duchies of Schleswig and Holstein, also known as Ducal Holstein, that were ruled by the dukes of Schleswig-Holstein-Gottorp, a side branch of the elder Danish line of the German House of Oldenburg. Other parts of the duchies were ruled by the kings of Denmark.
Knyaz, also knez, knjaz or kniaz, is a historical Slavic title, used both as a royal and noble title in different times. It is usually translated into English as "prince", "king", or "duke" depending on specific historical context and the potentially known Latin equivalents at the time, but the word was originally derived from the common Germanic *kuningaz (king).
Traditional rank amongst European imperiality, royalty, peers, and nobility is rooted in Late Antiquity and the Middle Ages. Although they vary over time and among geographic regions, the following is a reasonably comprehensive list that provides information on both general ranks and specific differences. Distinction should be made between reigning families and the nobility – the latter being a social class subject to and created by the former.
Grand prince or great prince is a title of nobility ranked in honour below Emperor, equal to Archduke, King, Grand duke and Prince-Archbishop; above a Sovereign Prince and Duke.
His/Her Serene Highness is a style used today by the reigning families of Liechtenstein, Monaco and Thailand. Over the past 400 years, it has also been used as a style for senior members of the family of Hazrat Ishaan, who are believed to succeed Prophet Muhammad based on the 1400 year old Sunni Sayyid ul Sadatiyya line of Emarat of Ahlul Bayt. Until 1918, it was also associated with the princely titles of members of some German ruling and mediatised dynasties and with a few princely but non-ruling families. It was also the form of address used for cadet members of the dynasties of France, Italy, Russia and Ernestine Saxony, under their monarchies. Additionally, the treatment was granted for some, but not all, princely yet non-reigning families of Bohemia, Hungary, Italy, Poland, Romania and Russia by emperors or popes. In a handful of rare cases, it was employed by non-royal rulers in viceregal or even republican contexts.
Prince John Konstantonovich of Russia, born as Grand Duke John Konstantinovich of Russia, sometimes also known as Prince Ivan, Prince Ioann or Prince Johan, was the eldest son of Grand Duke Konstantin Konstantinovich of Russia by his wife, Yelizaveta Mavrikievna, née Princess Elisabeth of Saxe-Altenburg. He was described by contemporaries as a gentle, religious person, nicknamed "Ioannchik" by his relatives.
Some titles of nobility outside Europe may be considered as equivalents of Duke.
The Qing dynasty (1644–1912) of China developed a complicated peerage system for royal and noble ranks.
Tsar is a title historically used by Slavic monarchs. The term is derived from the Latin word caesar, which was intended to mean emperor in the European medieval sense of the term—a ruler with the same rank as a Roman emperor, holding it by the approval of another emperor or a supreme ecclesiastical official—but was usually considered by Western Europeans to be equivalent to "king".
