Dimitrije "Mita" Ruvarac (Serbian: Димитрије Руварац ; Stari Banovci, Austria Hungary October 25, 1842 — Sremski Karlovci, Kingdom of Yugoslavia December 16, 1931) was Serbian historian, Orthodox priest, politician and publisher.
 He is known for being one of the most active publishers of his time.
Liborius Ritter von Frank (5 October 1848 — 26 February 1935) was an Austro-Hungarian general in World War I.
 He commanded the Austrian Fifth Army in 1914 at the start of the war, and fought at the Battle of Cer, Battle of Drina and Battle of Kolubara.
 He was replaced after the last battle for poor performance and large casualties suffered by his army that was reduced to about 40% of its strength at the moment of his replacement.
Carabus hungaricus is a beetle species native to the Palearctic.
 The European distribution of Carabus hungaricus is disjunctive – three major distribution areas can be distinguished: A) Ukrainian and Russian steppes, B) Bulgaria (small isolated area), and C) the Carpathian Basin.
 In its whole distribution area, the habitats where this species occurs are fragmented, and as a result often isolated.
 In Europe, it is found in Austria, Bulgaria, the Czech Republic, Hungary, Moldova, Romania, central and southern Russia, Serbia, Slovakia and Ukraine.
 It is a typical steppe species, inhabits sandy grasslands and dolomitic grasslands.
 The majority of its populations inhabit calcareous sandy grasslands from the Deliblat (Serbia: Deliblatska Peščara) throughout the Banat (Serbia, Romania) and sandy areas in Hungary along the Danube River all the way to Vienna (Austria) and South Moravia (Czech Republic).
 Numerous populations occur on acidic types of sand grasslands in the Nyírség area, near the city of Debrecen (Hungary).
 A classical collecting place for this beetle was in the dolomitic grasslands of Buda Mountains, near Budapest the capital city of Hungary.
Franz Xaver Ritter von Epp, from 1916 "Ritter von Epp", (16 October 1868 – 31 January 1947) was a German general and politician, who had started his military career in the Bavarian Army.
 Succeeded and merited military service during war brought him a knighthood in 1916.
 After the armistice of Germany and dissolution of Empire, von Epp was a commanding officer in Freikorps and Reichswehr.
 He was member of Bavarian People's Party before joining with Nazi Party in 1928, when he got elected as a member of German parliament, Reichstag, to the position he held until the end of Third Reich.
 He acted as "Reichskommissar", later "Reichsstatthalter", for Bavaria in 1933.
A Byzantine–Hungarian War was fought between Byzantine and Hungarian forces on the Danube between 1127 and 1129.
 According to the Byzantine chronicler Niketas Choniates, the citizens of the Byzantine town Braničevo "attacked and plundered the Hungarians who had come to" the Byzantine Empire "to trade, perpetrating the worst crimes against them."
 Stephen II of Hungary broke into the empire in the summer.
 His troops sacked Belgrade, Braničevo and Niš, and plundered the regions around Serdica (Sofia, Bulgaria) and Philippopolis (Plovdiv, Bulgaria), before returning to Hungary.
 In response, Emperor John II marched against Hungary in 1128, where he defeated the royal troops in a battle at Haram, and "captured Frangochorion, the richest land in Hungary" (now in Serbia).
 Following his victory over the Hungarians John II launched a punitive raid against the Serbs.
 Dangerously for the Byzantines the Serbs had aligned themselves with Hungary.
 Many Serbian prisoners were taken, and these were transported to Nicomedia in Asia Minor to serve as military colonists.
 This was done partly to cow the Serbs into submission (Serbia was, at least nominally, a Byzantine protectorate), and partly to strengthen the Byzantine frontier in the east against the Turks.
 The Serbs were forced to acknowledge Byzantine suzerainty once again.
 In Hungary, the defeat at Haram undermined Stephen II's authority and he faced a serious revolt when two counts, named 'Bors' (possibly Boris Kalamanos) and 'Ivan', were declared kings.
 Both were eventually defeated, Ivan being beheaded and Bors fleeing to Byzantium.
 Stephen was unable to participate in any of the fighting because he was sick, recuperating in his homeland, according to John Kinnamos.
 John Kinnamos wrote of a second campaign by Stephen against the Byzantine Empire, when the Hungarian troops, supported by Bohemian reinforcements under the command of Duke Václav of Olomouc, took Braničevo by storm and destroyed its fortress.
 The Hungarians had renewed hostilities, possibly in order that King Stephen could be seen to reassert his authority, by attacking the Byzantine frontier fortress of Braničevo, which was immediately rebuilt by John.
 Further Byzantine military successes – Choniates mentions several engagements – resulted in a restoration of peace.
 Cinnamus describes a Byzantine reverse occurring before peace was established, which suggests that the campaign was not entirely one-sided.
 Hungarian records, however, agree with Choniates in indicating that King Stephen was again defeated and was consequently forced to negotiate a peace on Byzantine terms.
 Historian Ferenc Makk thinks that Emperor John II Komnenos was forced to retreat and sue for peace and that the treaty was signed in October 1129.
 The Byzantines were confirmed in their control of Braničevo, Belgrade, and Zemun and they also recovered the region of Syrmia (called Frangochorion in Choniates), which had been in Hungarian hands since the 1060s.
 The Hungarian pretender Álmos died in 1129, removing the major source of friction.
The Battle of Kolubara (Serbian: Колубарска битка, "Kolubarska bitka" , German: "Schlacht an der Kolubara" ) was fought between Austria-Hungary and Serbia in November and December 1914, during the Serbian Campaign of World War I.
 It commenced on 16 November, when the Austro-Hungarians under the command of Oskar Potiorek reached the Kolubara River during their third invasion of Serbia that year, having captured the strategic town of Valjevo and forced the Serbian Army to undertake a series of retreats.
 The Serbs withdrew from Belgrade on 29–30 November, and the city soon fell under Austro-Hungarian control.
 On 2 December, the Serbian Army launched a surprise counter-attack all along the front.
 Valjevo and Užice were retaken by the Serbs on 8 December and the Austro-Hungarians retreated to Belgrade, which 5th Army commander Liborius Ritter von Frank deemed to be untenable.
 The Austro-Hungarians abandoned the city between 14 and 15 December and retreated back into Austria-Hungary, allowing the Serbs to retake their capital the following day.
The Arnold Ritter von Harff's lexicon is the second most ancient Albanian-language document ever retrieved, after the Formula e Pagëzimit.
 The lexicon was written by Arnold Ritter von Harff, a German traveler, who in 1496 was spending some hours in the port of Durrës and transcribed some words of the locals, by writing on the side, the German translation of them.
 The document includes 26 words in Albanian, 8 expressions, and numbers from 1 to 10, and also 100, and 1000.
Anton Dominik Ritter von Fernkorn (March 17, 1813 in Erfurt – November 16, 1878 in Vienna) was a German-Austrian sculptor.
The Montenegrin Campaign of World War I, in January 1916, was a part of the Serbian Campaign, in which Austria Hungary defeated and occupied the Kingdom of Montenegro, an ally of Serbia.
Eva von Sacher-Masoch, Baroness Erisso (1911–1991) was an Austrian aristocrat, great-niece of utopian humanist author Leopold von Sacher-Masoch (1836–1895) whose father Leopold Johann Nepomuk Ritter von Sacher ("Ritter" meaning knight, a title of nobility), combined his own with the von Masoch Slovak aristocratic title of his wife (last in that line) when his loyal services as Commissioner of the Imperial Police Forces in Lemberg (in present-day Ukraine) were rewarded with a new title, , by the Austrian Emperor.
