This is a list of heads of state, heads of governments, and other rulers in the year 1265.
A head of state is the public persona who officially represents the national unity and legitimacy of a sovereign state. Depending on the country's form of government and separation of powers, the head of state may be a ceremonial figurehead or concurrently the head of government. In a parliamentary system, such as India, the head of state usually has mostly ceremonial powers, with a separate head of government. However in some parliamentary systems, like South Africa, there is an executive president that is both head of state and head of government. Likewise, in some parliamentary systems the head of state is not the head of government, but still has significant powers, for example Morocco. In contrast, a semi-presidential system, such as France, has both heads of state and government as the de facto leaders of the nation. Meanwhile, in presidential systems such as the United States, the head of state is also the head of government.
The head of government is either the highest or second highest official in the executive branch of a sovereign state, a federated state, or a self-governing colony, who often presides over a cabinet, a group of ministers or secretaries who lead executive departments. "Head of government" is often differentiated from "head of state", as they may be separate positions, individuals, or roles depending on the country.
Emperor Kameyama was the 90th emperor of Japan, according to the traditional order of succession. His reign spanned the years from 1259 through 1274.
The Kamakura shogunate was a Japanese feudal military government of imperial-aristocratic rule that ruled from 1185 to 1333. The heads of the government were the shōguns. The first three were members of the Minamoto clan. The next two were members of the Fujiwara clan. The last six were minor Imperial princes.
Prince Munetaka (宗尊親王) was the sixth shōgun of the Kamakura shogunate of Japan who reigned from 1252 to 1266.
Goryeo was a Korean kingdom founded in 918, during a time of national division called the Later Three Kingdoms period, that unified and ruled the Korean Peninsula until 1392. Goryeo achieved what has been called a "true national unification" by Korean historians as it not only unified the Later Three Kingdoms but also incorporated much of the ruling class of the northern kingdom of Balhae, who had origins in Goguryeo of the earlier Three Kingdoms of Korea. The name "Korea" is derived from the name of Goryeo, also spelled Koryŏ, which was first used in the early 5th century by Goguryeo.
Wonjong of Goryeo was the 24th ruler of the Goryeo dynasty of Korea from 1260 to 1274.
The Kamakura period is a period of Japanese history that marks the governance by the Kamakura shogunate, officially established in 1192 in Kamakura by the first shōgun, Minamoto no Yoritomo. The period is known for the emergence of the samurai, the warrior caste, and for the establishment of feudalism in Japan.
The Margraviate of Baden was a historical territory of the Holy Roman Empire. Spread along the east side of the Upper Rhine River in southwestern Germany, it was named a margraviate in 1112 and existed until 1535, when it was split into the two margraviates of Baden-Durlach and Baden-Baden. The two parts were reunited in 1771 under Margrave Charles Frederick. The restored Margraviate of Baden was elevated to the status of electorate in 1803. In 1806, the Electorate of Baden, receiving territorial additions, became the Grand Duchy of Baden. The rulers of Baden, known as the House of Baden, were a cadet line of the Swabian House of Zähringen.
Frederick I of Baden, a member of the House of Zähringen, was Margrave of Baden and of Verona, as well as claimant Duke of Austria from 1250 until his death. As a fellow campaigner of the Hohenstaufen king Conradin, he likewise was beheaded at the behest of King Charles I of Naples.
Rudolf I, Margrave of Baden served as Regent to Margrave Frederick I from 1250 until 1267, then as Margrave of Baden from 1268 until his death in 1288.
The Principality of Achaea or of the Morea was one of the three 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.
The Kingdom of Aragon was a medieval and early modern kingdom on the Iberian Peninsula, corresponding to the modern-day autonomous community of Aragon, in Spain. It should not be confused with the larger Crown of Aragon, that also included other territories — the Principality of Catalonia, the Kingdom of Valencia, the Kingdom of Majorca, and other possessions that are now part of France, Italy, and Greece — that were also under the rule of the King of Aragon, but were administered separately from the Kingdom of Aragon.
James I the Conqueror was King of Aragon, Count of Barcelona, and Lord of Montpellier from 1213 to 1276; King of Majorca from 1231 to 1276; and Valencia from 1238 to 1276. His long reign—the longest of any Iberian monarch—saw the expansion of the House of Aragon and House of Barcelona in three directions: Languedoc to the north, the Balearic Islands to the southeast, and Valencia to the south. By a treaty with Louis IX of France, he wrested the County of Barcelona from nominal French suzerainty and integrated it into his crown. He renounced northward expansion and taking back the once Catalan territories in Occitania and vassal counties loyal to the County of Barcelona, lands that were lost by his father Peter II of Aragon in the Battle of Muret during the Albigensian Crusade and annexed by the Kingdom of France, and then decided to turn south. His great part in the Reconquista was similar in Mediterranean Spain to that of his contemporary Ferdinand III of Castile in Andalusia. One of the main reasons for this formal renunciation of most of the once Catalan territories in Languedoc and Occitania and any expansion into them is the fact that he was raised by the Knights Templar crusaders, who had defeated his father fighting for the Pope alongside the French, so it was effectively forbidden for him to try to maintain the traditional influence of the Count of Barcelona that previously existed in Occitania and Languedoc.
