The Treaty of Akhal was a treaty signed by Persia and Imperial Russia on 21 September 1881.
 The treaty marked Persia's official recognition of Khwarazm's annexation by the Russian Empire.
 Although Persia had won a clear victory in the last Ottoman–Persian War (1821–23) over their Ottoman arch rivals, it had been considerably weakened by years of ineffective rulers, the defeat against Russia in 1813 and 1828 in which they lost all of the Caucasus, and with the increasing occupation by Great Britain of Egypt, during the years of 1873 to 1881, and on top of that the decaying Ottoman Empire, Imperial Russia stepped up its campaign to wrest full control over Central Asia.

 Hence forces led by Generals Mikhail Skobelev, Ivan Lazarev, and Konstantin Kaufman spearheaded the campaign, with Persia unable to react.
 The immobilized Naser al-Din Shah Qajar sent foreign secretary "Mirza Sa'eed Khan Mo'tamen ol-Mulk" to meet Ivan Zinoviev and sign a treaty in Tehran.

 It is also mentioned as being part of the 6th district by Herodotus, which also included Cyrene, a Greek colony in Libya.
 When King Cambyses II of Persia conquered Egypt, the king of Cyrene, Arcesilaus III, sided with Persia.
 When he was killed trying to maintain power, Queen Pheretima invited the Persians to take Cyrene.
 The satrap of Egypt, Aryandes, accepted, sending an army under two Persians to support Pheretime.
 The expedition lasted nearly a year and resulted in the subjugation of the Libyans; the Persians penetrated as far west as the Euseperides (Benghazi).
 A puppet king, Battus IV, was installed, and Libya was made into a Persian satrapy.
 It is possible that Cyrene gained independence with the rebellion of Egypt in 404 BCE, but ultimately, Achaemenid control of the region was lost after Alexander's conquests.
The Persian Empire (Persian: شاهنشاهی ایران, translit.
 "shāhanshāhi-ye irān", lit.
 'Imperial Iran') is one of a series of imperial dynasties centered in Iran (formerly known as Persia in the Western world until 1935).
 Persia was in power from 550 B.C. until 330 B.C.
 The first of these was the Achaemenid Empire established by Cyrus the Great in 550 BC with the conquest of Median, Lydian and Babylonian empires.
 It covered much of the Ancient world when it was conquered by Alexander the Great.
 Persia was then ruled by the Parthian Empire, which supplanted the Hellenistic Seleucid Empire, and then by the Sassanian Empire, which ruled up until the mid-7th century.
The Ionian Revolt, and associated revolts in Aeolis, Doris, Cyprus and Caria, were military rebellions by several Greek regions of Asia Minor against Persian rule, lasting from 499 BC to 493 BC.
 At the heart of the rebellion was the dissatisfaction of the Greek cities of Asia Minor with the tyrants appointed by Persia to rule them, along with the individual actions of two Milesian tyrants, Histiaeus and Aristagoras.
 The cities of Ionia had been conquered by Persia around 540 BC, and thereafter were ruled by native tyrants, nominated by the Persian satrap in Sardis.
 In 499 BC, the tyrant of Miletus, Aristagoras, launched a joint expedition with the Persian satrap Artaphernes to conquer Naxos, in an attempt to bolster his position.
 The mission was a debacle, and sensing his imminent removal as tyrant, Aristagoras chose to incite the whole of Ionia into rebellion against the Persian king Darius the Great.
Limyra (in Greek Λιμύρα) was a small city in Lycia on the southern coast of Asia Minor, on the Limyrus River, and twenty stadia from the mouth of that river.It was a prosperous city, and one of the oldest cities in lycia.
 The city had rich and abundant soil, and gradually became one of the finest trade settlements in Greece.
 Pericles adopted it as the capital of the lycian league.
 The city came under control of the Persian Empire after it was conquered by Cyrus the Great.
 He later annexed Lydia and its territories after a decisive victory at the Battle of Thymbra and the Siege of Sardis, where he defeated armies twice as large as his.
 Cyrus then got his greatest general: Harpagus of Media to conquer the much smaller kingdoms in Anatolia, while he went to conquer the Neo-Babylonian Empire.
 Anatolia would become an important place for the Persian monarchs who succeeded Cyrus.
 The massive Royal road constructed by Darius went from the Persian capital of Persepolis, to the Anatolian city of Sardis.
 Limyra would stay under Persian control until the very end of its days, when it was conquered and sacked by Alexander the Great.
The Agalassoi were a tribe that lived in modern Pakistan in the lower Indus Valley at the time of Alexander the Great.
 During Alexander's invasion of India, the Agalassoi were defeated in battle by the Macedonian army.
After the devastating invasions by Timur and subsequent enfeeblement of the Kingdom of Georgia, it soon faced a new threat.
 Timur's death in 1405 marked the beginning of the end of his Empire, unified only by fear and blood of the subjected peoples.
 Turkomans, particularly the Kara Koyunlu clan, were among the first to rebel against Shah Rukh who ruled most of the Persia and Mawerannahr.
 Qara Yusuf, ruler of the Kara Koyunlu, defeated Shah Rukh, captured Baghdad, and repulsed Timurids from western Persia.
 After they established themselves as the new leading power in the middle east.
 They took advantage of the temporary weakness of Georgians and launched attacks against them, apparently in which, George VII of Georgia was killed.
 Constantine I of Georgia, fearing further encroachment, allied himself with the Shirvanshah Ibrahim I to counter Turkoman advance and engaged them in the Battle of Chalagan, in which he was defeated and taken captive.
 In captivity Constantine behaved very proudly, which infuriated Qara Yusuf to such an extent, that he ordered his, his half-brother David's and 300 Georgian nobles' execution.
Megabazus was a highly regarded Persian general under Darius.
 Most information about him comes from "The Histories" by Herodotus.
 Troops left behind in Europe after a failed attempt to fully conquer the Scythians were put under the command of Megabazus.
 The Persian troops subjugated gold-rich Thrace, the coastal Greek cities, and defeated the powerful Paeonians.
 Finally, Megabazus sent envoys to Amyntas I, demanding acceptation of Persian domination, which the Macedonian accepted.
 He then removed the Paeonians from their homeland and brought them to Darius in Sardis.
 Megabazus was suspicious of Histiaeus and advised Darius to bring him to Susa to keep a closer eye on him.
 His suspicions turned out to be true as Histiaeus provoked a revolt in the town he was formally in charge of and later sided with the Greeks against Persia.
 The successor to Megabazus's command was Otanes.
Xerxes I ( ; Old Persian: 𐎧𐏁𐎹𐎠𐎼𐏁𐎠</a> x-š-y-a-r-š-a (   ) "ruling over heroes", <a href="Ancient%20Greek">Greek</a> Ξέρξης ] ; 518–465 BC), called Xerxes the Great, was the <a href="List%20of%20kings%20of%20Persia%23Achaemenid%20Empire%20%28550%E2%80%93330%20BC%29">fourth</a> <a href="king%20of%20kings">king of kings</a> of the <a href="Achaemenid%20Empire">Achaemenid dynasty <a href="Persia">Persia</a>.
 Like his predecessor Darius I, he ruled the empire at its territorial apex.
 He ruled from 486 BC until his assassination in 465 BC at the hands of Artabanus, the commander of the royal bodyguard.
The Indian campaign of Alexander the Great began in 326BC.
 After conquering the Achaemenid Empire of Persia, the Macedonian king (and now the great king of the Persian Empire), Alexander, launched a campaign into the Indian subcontinent.
 The rationale for this campaign is usually said to be Alexander's desire to conquer the entire known world, which the Greeks thought ended in India.
