Varazdat (Middle Persian: Warāzdātan), was an Iranian nobleman who served as the marzban of Persian Armenia from 560 to 564. During his governorship, Armenia was relatively peaceful. In 561, the Sasanian Empire and the Byzantine Empire, concluded a peace treaty known as the "Fifty-Year Peace Treaty", which ended the Lazic War. In 564, Varazdat was succeeded by Chihor-Vishnasp.
The Treaty of Lausanne was a peace treaty negotiated during the Lausanne Conference of 1922–23 and signed in the Palais de Rumine, Lausanne, Switzerland, on 24 July 1923. The treaty officially settled the conflict that had originally existed between the Ottoman Empire and the Allied French Republic, British Empire, Kingdom of Italy, Empire of Japan, Kingdom of Greece, and the Kingdom of Romania since the onset of World War I. The original text of the treaty is in French. It was the result of a second attempt at peace after the failed and unratified Treaty of Sèvres, which aimed to divide Ottoman lands. The earlier treaty had been signed in 1920, but later rejected by the Turkish National Movement who fought against its terms. As a result of Greco-Turkish War, İzmir was retrieved and the Armistice of Mudanya was signed in October 1922. It provided for the Greek-Turkish population exchange and allowed unrestricted civilian passage through the Turkish Straits.
The Treaty of Gulistan was a peace treaty concluded between the Russian Empire and Iran on 24 October 1813 in the village of Gulistan as a result of the first full-scale Russo-Persian War. The peace negotiations were precipitated by the successful storming of Lankaran by General Pyotr Kotlyarevsky on 1 January 1813. It was the first of the series of treaties signed between Qajar Iran and Imperial Russia that forced Persia to cede or recognize Russian influence over the territories that formerly were part of Iran.
Mamikonian or Mamikonean was an aristocratic dynasty which dominated Armenian politics between the 4th and 8th century. They were the most notable noble house in Early Christian Armenia after the ruling Arsacid dynasty and held the hereditary positions of sparapet and dayeak, allowing them to play the role of kingmaker for the later Armenian kings. They ruled over extensive territories, including the Armenian regions of Tayk, Taron, Sasun, and Bagrevand, among others. The Mamikonians had a reputation as supporters of the Roman Empire in Armenia against Sasanian Iran, although they also served as viceroys under Persian rule. Their influence over Armenian affairs began to decline at the end of the 6th century and suffered a final, decisive blow after a failed rebellion against Arab rule over Armenia in 774/75.
Pap, also known as Papas, was King of Armenia from 370 until 374/375, and a member of the Arsacid dynasty. His reign saw a short, but notable period of stabilization after years of political turmoil. Pap ascended to the throne at a young age with Roman assistance in 370 after Armenia had been conquered and devastated by the Sassanid king Shapur II. Early in his reign, Armenia and Rome won a joint victory over the Persians at the Battle of Bagavan, and some former terrritories of the kingdom were reconquered by the efforts of his sparapet (general-in-chief) Mushegh Mamikonian. Although Pap's reign began with a reconciliation of the monarchy, nobility and church, his relations with the church soon deteriorated. Pap allegedly had the Patriarch of Armenia, Nerses I, poisoned, although some later historians doubt this narrative. Pap also eventually ran afoul of the Romans, who suspected him of colluding with the Persians. The emperor Valens had him assassinated in 374/375. He was succeeded by his nephew Varazdat as king.
The Roman–Persian Wars, also known as the Roman–Iranian Wars, were a series of conflicts between states of the Greco-Roman world and two successive Iranian empires: the Parthian and the Sasanian. Battles between the Parthian Empire and the Roman Republic began in 54 BC; wars began under the late Republic, and continued through the Roman and Sasanian empires. A plethora of vassal kingdoms and allied nomadic nations in the form of buffer states and proxies also played a role. The wars were ended by the early Muslim conquests, which led to the fall of the Sasanian Empire and huge territorial losses for the Byzantine Empire, shortly after the end of the last war between them.
The Arsacid dynasty or Arshakuni, ruled the Kingdom of Armenia from 12 to 428. The dynasty was a branch of the Arsacid dynasty of Parthia. Arsacid kings reigned intermittently throughout the chaotic years following the fall of the Artaxiad dynasty until 62 when Tiridates I secured Parthian Arsacid rule in Armenia. However, he did not succeed in establishing his line on the throne, and various Arsacid members of different lineages ruled until the accession of Vologases II, who succeeded in establishing his own line on the Armenian throne, which would rule the country until it was abolished by the Sasanian Empire in 428.
The 1804–1813 Russo-Persian War was one of the many wars between the Persian Empire and Imperial Russia, and began like many of their wars as a territorial dispute. The new Persian king, Fath Ali Shah Qajar, wanted to consolidate the northernmost reaches of his kingdom—modern-day Georgia—which had been annexed by Tsar Paul I several years after the Russo-Persian War of 1796. Like his Persian counterpart, the Tsar Alexander I was also new to the throne and equally determined to control the disputed territories.
The Russo-Persian War of 1826–1828 was the last major military conflict between the Russian Empire and Persia.

Varazdat was a king of Arsacid Armenia from 374 until 378.
The Treaty of Zuhab, also called Treaty of Qasr-e Shirin, was an accord signed between the Safavid Empire and the Ottoman Empire on May 17, 1639. The accord ended the Ottoman-Safavid War of 1623–1639 and was the last conflict in almost 150 years of intermittent wars between the two states over territorial disputes. It can roughly be seen as a confirmation of the previous Peace of Amasya from 1555.
Arshak II, also written as Arsaces II or Aršak II, was an Arsacid prince who was King of Armenia from 350 until c. 364/367. Although Arshak's reign opened with a period of peace and stability, it was soon plagued by his conflicts with the Armenian church and nobility, as well as a series of wars between Rome and Persia, during which the Armenian king teetered between the warring sides. Arshak participated in the Roman emperor Julian's ill-fated campaign against Persia; after the consequent Perso-Roman Treaty of 363, Armenia was left to fend for itself against a renewed attack by the Persian king Shapur II. Faced with defections and rebellions among the Armenian nobility, Arshak was lured to Persia for peace negotiations with Shapur, after which he was imprisoned in the Castle of Oblivion and is said to have committed suicide. Arshak's reign was followed by the conquest and devastation of Armenia by the Persians, although his son and heir Pap managed to escape and later ascended to the Armenian throne with Roman assistance.
The partition of the Ottoman Empire was a geopolitical event that occurred after World War I and the occupation of Constantinople by British, French and Italian troops in November 1918. The partitioning was planned in several agreements made by the Allied Powers early in the course of World War I, notably the Sykes-Picot Agreement, after the Ottoman Empire had joined Germany to form the Ottoman–German Alliance. The huge conglomeration of territories and peoples that formerly comprised the Ottoman Empire was divided into several new states. The Ottoman Empire had been the leading Islamic state in geopolitical, cultural and ideological terms. The partitioning of the Ottoman Empire after the war led to the domination of the Middle East by Western powers such as Britain and France, and saw the creation of the modern Arab world and the Republic of Turkey. Resistance to the influence of these powers came from the Turkish National Movement but did not become widespread in the other post-Ottoman states until the period of rapid decolonization after World War II.
Sasanian Armenia, also known as Persian Armenia and Persarmenia, may either refer to the periods in which Armenia was under the suzerainty of the Sasanian Empire or specifically to the parts of Armenia under its control such as after the partition of 387 when parts of western Armenia were incorporated into the Eastern Roman Empire while the rest of Armenia came under Sasanian suzerainty but maintained its existing kingdom until 428.
The Armenian question was the debate following the Congress of Berlin in 1878 as to how the Armenians in the Ottoman Empire should be treated. The term became commonplace among diplomatic circles and in the popular press. In specific terms, the Armenian question refers to the protection and the freedoms of Armenians from their neighboring communities. The Armenian question explains the 40 years of Armenian–Ottoman history in the context of English, German, and Russian politics between 1877 and 1914. In 1915, the leadership of the Committee of Union and Progress, which controlled the Ottoman government, decided to end the Armenian question permanently by killing and expelling most Armenians from the empire, in the Armenian genocide.
The Peace of Amasya was a treaty agreed to on May 29, 1555, between Shah Tahmasp of Safavid Iran and Sultan Suleiman the Magnificent of the Ottoman Empire at the city of Amasya, following the Ottoman–Safavid War of 1532–1555.
Manuel Mamikonian was the real leader of Armenia after the exile of King Varasdates (Varazdat) who ruled from 374 until 378. The Mamikonian family had long been the leading generals of Armenia, holding the title of sparapet, commander-in-chief.
Mushegh I Mamikonian was an Armenian military officer from the Mamikonian family, who occupied the hereditary office of sparapet (generalissimo) of the Kingdom of Armenia under the Arsacid kings Pap and Varazdat. He took part in the Armenian resistance against the forces of the Sasanian monarch Shapur II, notably taking part in the Battle of Bagavan, where the Iranian forces were defeated. He was the regent of Armenia under the young and inexperienced Varazdat, who eventually suspected him of posing a danger to his rule, and thus had him executed, in 377/8.
The history of the Caucasus region may be divided by geography into the history of the North Caucasus (Ciscaucasia), historically in the sphere of influence of Scythia and of Southern Russia, and that of the South Caucasus in the sphere of influence of Persia, Anatolia, and Assyria.
The Ottoman–Safavid War of 1623–1639 was the last of a series of conflicts fought between the Ottoman Empire and Safavid Empire, then the two major powers of Western Asia, over control of Mesopotamia. After initial Persian success in recapturing Baghdad and most of modern Iraq, having lost it for 90 years, the war became a stalemate as the Persians were unable to press further into the Ottoman Empire, and the Ottomans themselves were distracted by wars in Europe and weakened by internal turmoil. Eventually, the Ottomans were able to recover Baghdad, taking heavy losses in the final siege, and the signing of the Treaty of Zuhab ended the war in an Ottoman victory. Roughly speaking, the treaty restored the borders of 1555, with the Safavids keeping Dagestan, eastern Georgia, Eastern Armenia, and the present-day Azerbaijan Republic, while western Georgia and Western Armenia decisively came under Ottoman rule. The eastern part of Samtskhe (Meskheti) was irrevocably lost to the Ottomans as well as Mesopotamia. Although parts of Mesopotamia were briefly retaken by the Iranians later on in history, notably during the reigns of Nader Shah (1736–1747) and Karim Khan Zand (1751–1779), it remained thenceforth in Ottoman hands until the aftermath of World War I.
Tan-Shapur was a Sasanian nobleman who served as Marzban of Persian Armenia from 552/554 to 560.
