Basil II Porphyrogenitus, nicknamed the Bulgar Slayer, was the senior Byzantine emperor from 976 to 1025. He and his brother Constantine VIII were crowned before their father Romanos II died in 963, but they were too young to rule. The throne thus went to two generals, Nikephoros Phokas and John Tzimiskes before Basil became senior emperor, though his influential great-uncle Basil Lekapenos remained as the de facto ruler until 985. His reign of 49 years and 11 months was the longest of any Roman emperor.
Romanos IV Diogenes was Byzantine emperor from 1068 to 1071. Determined to halt the decline of the Byzantine military and to stop Turkish incursions into the empire, he is nevertheless best known for his defeat and capture in 1071 at the Battle of Manzikert, which played a major role in undermining Byzantine authority in Anatolia and allowed for its gradual Turkification.
The Battle of Manzikert or Malazgirt was fought between the Byzantine Empire and the Seljuk Empire on 26 August 1071 near Manzikert, theme of Iberia. The decisive defeat of the Byzantine army and the capture of the Emperor Romanos IV Diogenes played an important role in undermining Byzantine authority in Anatolia and Armenia, and allowed for the gradual Turkification of Anatolia. Many Turks, travelling westward during the 11th century, saw the victory at Manzikert as an entrance to Asia Minor.
John I Tzimiskes was the senior Byzantine emperor from 969 to 976. An intuitive and successful general who married into the influential Skleros family, he strengthened and expanded the Byzantine Empire to include Thrace and Syria by warring with the Rus' under Sviatoslav I and the Fatimids respectively.
The Battle of Kleidion took place on July 29, 1014, between the Byzantine Empire and the Bulgarian Empire. It was the culmination of the nearly half-century struggle between the Byzantine Emperor Basil II and the Bulgarian emperor Samuel in the late 10th and early 11th centuries. The result was a decisive Byzantine victory.
The Polish–Russian War of 1792 was fought between the Polish–Lithuanian Commonwealth on one side, and the Targowica Confederation and the Russian Empire under Catherine the Great on the other.
The Battle of Achelous or Acheloos, also known as the Battle of Anchialus, took place on 20 August 917, on the Achelous river near the Bulgarian Black Sea coast, close to the fortress Tuthom between Bulgarian and Byzantine forces. The Bulgarians obtained a decisive victory which not only secured the previous successes of Simeon I, but made him de facto ruler of the whole Balkan Peninsula, excluding the well-protected Byzantine capital Constantinople and the Peloponnese. The battle, which was one of the biggest and bloodiest battles of the European Middle Ages, was one of the worst disasters ever to befall a Byzantine army, and conversely one of the greatest military successes of Bulgaria. Among the most significant consequences was the official recognition of the imperial title of the Bulgarian monarchs, and the consequent affirmation of Bulgarian equality vis-à-vis Byzantium.
Jędrzej Edward Moraczewski was a Polish socialist politician who, loyal to Józef Piłsudski and viewed as acceptable by both left- and right-wing Polish political factions, served as the second Prime Minister of the Second Polish Republic between November 1918 and January 1919. He had previously served as Minister of Communications. Subsequently, from 1925 to 1929, he served as Minister of Public Labour.
Ossoliński National Institute, or the Ossolineum is a Polish cultural foundation, publishing house, archival institute and a research centre of national significance founded in 1817 in Lwów. Located in the city of Wrocław since 1947, it is the second largest institution of its kind in Poland after the ancient Jagiellonian Library in Kraków. Its publishing arm is the oldest continuous imprint in Polish since the early 19th century. It bears the name of its founder, Polish nobleman, Count Józef Maksymilian Ossoliński (1748-1826).
Ivan Vladislav served as the emperor (tsar) of the First Bulgarian Empire from approximately August or September 1015 until February 1018. The precise year of his birth remains elusive; he was born at least ten years prior to 987, but likely not much earlier than that.
The Battle of Versinikia was fought in 813 between the Byzantine Empire and the Bulgarian Empire, near the city of Adrianople (Edirne) in modern-day Turkey.
The Battle of Lalakaon, or Battle of Poson or Porson, was fought in 863 between the Byzantine Empire and an invading Arab army in Paphlagonia. The Byzantine army was led by Petronas, the uncle of Emperor Michael III, although Arab sources also mention the presence of the Emperor in person. The Arabs were led by the emir of Melitene (Malatya), Umar al-Aqta.
The Battle of Arcadiopolis was fought in 970 between a Byzantine army under Bardas Skleros and a Rus' army, the latter also including allied Bulgarian, Pecheneg, and Hungarian (Magyar) contingents. In the preceding years, the Rus' ruler Sviatoslav had conquered northern Bulgaria, and was now menacing Byzantium as well. The Rus' force had been advancing through Thrace towards Constantinople when it was met by Skleros' force. Having fewer men than the Rus', Skleros prepared an ambush and attacked the Rus' army with a portion of his force. The Byzantines then feigned retreat, and succeeded in drawing off the Pecheneg contingent into the ambush, routing it. The remainder of the Rus' army then suffered heavy casualties from the pursuing Byzantines. The battle was important as it bought time for the Byzantine emperor John I Tzimiskes to settle his internal problems and assemble a large expedition, which eventually defeated Sviatoslav the next year.
The Battle of Rusokastro occurred on July 18, 1332 near the village of Rusokastro, Bulgaria, between the armies of the Bulgarian and Byzantine Empires. The outcome was a Bulgarian victory
The Battle of Silistra occurred in the spring of 968 near the Bulgarian town of Silistra, but most probably on the modern territory of Romania. It was fought between the armies of Bulgaria and Kievan Rus' and resulted in a Rus' victory. Upon the news of the defeat, the Bulgarian emperor Peter I abdicated. The invasion of the Rus' prince Sviatoslav was a heavy blow for the Bulgarian Empire, which by 971 lost its eastern provinces to the Byzantine Empire.
The Battle of Tryavna occurred in 1190, in the mountains around the contemporary town of Tryavna, central Bulgaria. The result was a Bulgarian victory over the Byzantine Empire, which secured the successes achieved since the beginning of the Rebellion of Asen and Peter in 1185.
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.
Polish–Bulgarian relations are foreign relations between Poland and Bulgaria. Both countries are full members of the European Union, NATO, Bucharest Nine, Three Seas Initiative, OSCE, Council of Europe and World Trade Organization.
