Andronikos III Palaiologos, commonly Latinized as Andronicus III Palaeologus, was the Byzantine emperor from 1328 to 1341. Born Andronikos Doukas Angelos Komnenos Palaiologos, he was the son of Michael IX Palaiologos and Rita of Armenia. He was proclaimed co-emperor in his youth, before 1313, and in April 1321 he rebelled in opposition to his grandfather, Andronikos II Palaiologos. He was formally crowned co-emperor in February 1325, before ousting his grandfather outright and becoming sole emperor on 24 May 1328.
Andronikos II Palaiologos, usually Latinized as Andronicus II Palaeologus, reigned as Byzantine Emperor from 1282 to 1328. Andronikos' reign was marked by the beginning of the decline of the Byzantine Empire. During his reign, the Turks conquered most of the Western Anatolian territories of the Empire and, during the last years of his reign, he also had to fight his grandson Andronikos in the First Palaiologan Civil War. The civil war ended in Andronikos II's forced abdication in 1328 after which he retired to a monastery, where he spent the last four years of his life.
Michael VIII Palaiologos or Palaeologus reigned as the co-emperor of the Empire of Nicaea from 1259 to 1261, and as Byzantine Emperor from 1261 until his death. Michael VIII was the founder of the Palaiologan dynasty that would rule the Byzantine Empire until the Fall of Constantinople in 1453. He recovered Constantinople from the Latin Empire in 1261 and transformed the Empire of Nicaea into a restored Byzantine Empire.
The Empire of Trebizond, or Trapezuntine Empire, was a monarchy and one of three successor rump states of the Byzantine Empire that flourished during the 13th through 15th centuries, consisting of the far northeastern corner of Anatolia and the southern Crimea. The empire was formed in 1204 with the help of the Georgian queen Tamar after the Georgian expedition in Chaldia and Paphlagonia, commanded by Alexios Komnenos a few weeks before the sack of Constantinople. Alexios later declared himself Emperor and established himself in Trebizond. Alexios and David Komnenos, grandsons and last male descendants of deposed Emperor Andronikos I Komnenos, pressed their claims as "Roman Emperors" against Byzantine Emperor Alexios V Doukas. The later Byzantine emperors, as well as Byzantine authors, such as George Pachymeres, Nicephorus Gregoras and to some extent Trapezuntines such as John Lazaropoulos and Basilios Bessarion, regarded the emperors of Trebizond as the "princes of the Lazes", while the possession of these "princes" was also called Lazica, in other words, their state was known as the Principality of the Lazes. Thus from the point of view of the Byzantine writers connected with the Laskaris and later with the Palaiologos dynasties, the rulers of Trebizond were not emperors.
The Byzantine navy was the naval force of the East Roman or Byzantine Empire. Like the empire it served, it was a direct continuation from its Imperial Roman predecessor, but played a far greater role in the defence and survival of the state than its earlier iteration. While the fleets of the unified Roman Empire faced few great naval threats, operating as a policing force vastly inferior in power and prestige to the legions, the sea became vital to the very existence of the Byzantine state, which several historians have called a "maritime empire".
The Second Bulgarian Empire was a medieval Bulgarian state that existed between 1185 and 1396. A successor to the First Bulgarian Empire, it reached the peak of its power under Tsars Kaloyan and Ivan Asen II before gradually being conquered by the Ottomans in the late 14th century.
The Despotate of Dobruja or Principality of Karvuna was a 14th-century quasi-independent polity in the region of modern Dobruja, that split off from the Second Bulgarian Empire under the influence of the Byzantine Empire.
In the medieval history of Europe, Bulgaria's status as the Bulgarian Empire, wherein it acted as a key regional power occurred in two distinct periods: between the seventh and eleventh centuries, and again between the twelfth and fourteenth centuries. The two "Bulgarian Empires" are not treated as separate entities, but rather as one state restored after a period of Byzantine rule over its territory.
The Byzantine–Bulgarian wars were a series of conflicts fought between the Byzantines and Bulgarians which began when the Bulgars first settled in the Balkan peninsula in the 5th century, and intensified with the expansion of the Bulgarian Empire to the southwest after 680 AD. The Byzantines and Bulgarians continued to clash over the next century with variable success, until the Bulgarians, led by Krum, inflicted a series of crushing defeats on the Byzantines. After Krum died in 814, his son Omurtag negotiated a thirty-year peace treaty. Simeon I, who ruled Bulgaria from 893 to 927 had multiple successful campaigns against the Byzantines. His son Peter I negotiated another long-lasting peace treaty. His rule was followed by a period of decline of the Bulgarian state.
The Ottoman Navy, also known as the Ottoman Fleet, was established in the early 14th century after the Ottoman Empire first expanded to reach the sea in 1323 by capturing Karamürsel, the site of the first Ottoman naval shipyard and the nucleus of the future Navy. During its long existence, it was involved in many conflicts and signed a number of maritime treaties. At its height, the Navy extended to the Indian Ocean, sending an expedition to Indonesia in 1565.
Salah Rais was an Ottoman privateer and admiral. He is alternatively referred to as Sala Reis, Salih Rais, Salek Rais and Cale Arraez in several European sources, particularly in Spain, France and Italy.
The Bulgarian–Ottoman wars were fought between the kingdoms remaining from the disintegrating Second Bulgarian Empire, and the Ottoman Empire, in the second half of the 14th century. The wars resulted with the collapse and subordination of the Bulgarian Empire, and effectively came to an end with the Ottoman conquest of Tarnovo in July 1393, although other Bulgarian territories, such as the Tsardom of Vidin, held out slightly longer. As a result of the wars the Ottoman Empire greatly expanded its territory on the Balkan peninsula, stretching from Danube to the Aegean Sea.
The Palaiologan army refers to the military forces of the Byzantine Empire under the rule of the Palaiologos dynasty, from the late 13th century to its final collapse in the mid-15th century. The army was a direct continuation of the forces of the Empire of Nicaea, which itself was a fractured component of the formidable Komnenian army of the 12th century. Under the first Palaiologan emperor, Michael VIII, the army's role took an increasingly offensive role whilst the naval forces of the empire, weakened since the days of Andronikos I Komnenos, were boosted to include thousands of skilled sailors and some 80 ships. Due to the lack of land to support the army, the empire required the use of large numbers of mercenaries.
The medieval Bulgarian army was the primary military body of the First and the Second Bulgarian Empires, and some Puppet states of the former, like the Despotate of Dobruja. During the first decades after the foundation of the country, the army consisted of a Bulgar cavalry and a Slavic infantry. The core of the Bulgarian army was the heavy cavalry, which consisted of ca. 12,000 heavily armed riders. At its height in the 9th and 10th centuries, it was one of the most formidable military forces in Europe and was feared by its enemies. There are several documented cases of Byzantine commanders abandoning an invasion because of a reluctance to confront the Bulgarian army on its home territory.
The Uprising of Ivaylo was a rebellion of the Bulgarian peasantry against the incompetent rule of Emperor Constantine Tikh and the Bulgarian nobility. The revolt was fuelled mainly by the failure of the central authorities to confront the Mongol menace in north-eastern Bulgaria. The Mongols had looted and ravaged the Bulgarian population for decades, especially in the region of Dobrudzha. The weakness of the state institutions was a result of the accelerating process of feudalisation of the Second Bulgarian Empire.
The Savoyard crusade was a crusading expedition to the Balkans in 1366–67. It was born out of the same planning that led to the Alexandrian Crusade and was the brainchild of Pope Urban V. It was led by Count Amadeus VI of Savoy and directed against the growing Ottoman Empire in eastern Europe. Although intended as a collaboration with the Kingdom of Hungary and the Byzantine Empire, the crusade was diverted from its main purpose to attack the Second Bulgarian Empire. There the crusaders made small gains that they handed over to the Byzantines. It did take back some territory the Ottomans in the vicinity of Constantinople and on Gallipoli.
Ivan Asen II, also known as John Asen II or John Asan II, was Emperor (Tsar) of Bulgaria from 1218 to 1241. He was still a child when his father Ivan Asen I – one of the founders of the Second Bulgarian Empire – was killed in 1196. His supporters tried to secure the throne for him after his uncle, Kaloyan, was murdered in 1207, but Kaloyan's other nephew, Boril, overcame them. Ivan Asen fled from Bulgaria and settled in the Rus' principalities.
Michael Palaiologos was a son of Byzantine emperor John V Palaiologos, governor of Mesembria and claimant of the Empire of Trebizond.
