Question: When did the Sassanids replace the Parthians? Passage 1:In 270 the Roman emperor Aurelian engaged the Sassanids, who had now replaced the Parthians, on the eastern front and he was able to drive them back. Tiridates, as the true heir to the now Persian-occupied Armenian throne, came to Armenia and quickly raised an army and drove the enemy out in 287. When Tiridates returned to Armenia, he made the city of Vagharshapat his capital, as it had been the capital of his late father. For a while, fortune appeared to favour Tiridates. He not only expelled his enemies, but he carried his arms into Assyria. At the time the Persian Empire was in a distracted state. The throne was disputed by the ambition of two contending brothers, Hormuz and Narses. The civil war was, however, soon terminated and Narses was universally acknowledged as King of Persia. Narses then directed his whole force against the foreign enemy. The contest then became too unequal. Tiridates once more took refuge with the Romans. The Roman-Armenian alliance grew stronger, especially while Diocletian ruled the empire. This can be attributed to the upbringing of Tiridates, the consistent Persian aggressions and the murder of his father by Anak. With Diocletian's help, Tiridates pushed the Persians out of Armenia. In 299, Diocletian left the Armenian state in a quasi-independent and protectorate status possibly to use it as a buffer in case of a Persian attack. Tiridates married an Alani Princess called Ashkhen in 297 by whom he had three children: a son called Khosrov III, a daughter called Salome and an unnamed daughter who married St. Husik I, one of the earlier Catholicoi of the Armenian Apostolic Church.
 Passage 2:Characters based on ancient Egyptian deities were first mentioned in Captain America Comics #20 (November 1942), published by Marvel Comics' predecessor Timely Comics, in which Captain America and Bucky investigate the murder of Colonel Fitzpatrick, who was studying the Book of Thoth while stationed in Egypt. The Heliopolitans first full Golden Age appearance was in the story "The Terror That Creeps" by Stan Lee and Werner Roth, published in Marvel Tales #96 (June 1950), and involves a man that fails to convince the public that the Great Sphinx of Giza is slowly moving to the edge of the desert, where it will be empowered by Set and destroy mankind. The goddess Bast would later make her first appearance (as a totem) with the Black Panther in Fantastic Four #52 (July 1966). Many of the other deities, including Horus, Isis and Osiris, were introduced in Thor #239 (September 1975). Khonshu, who became associated with Moon Knight, first appeared in Moon Knight #1 (November 1980). Joseph Muszynski argued in his book Everything I Needed to Know About Life I Learned from Marvel Comics that the introduction of Egyptian deities "excited our tendency to enjoy variety" as the pantheon contained multiple gods and personalities as opposed to the Judeo-Christian religions. Ed Strauss contended that Marvel was able to dive into ancient Egyptian religion because it "had long been retired into the realm of mythology" unlike Christianity.
 Passage 3:As part of the RAAF's reorganisation following the outbreak of World War II in September 1939, No. 2 Group was formed in Sydney on 20 November; Charlesworth was appointed its Senior Air Staff Officer (SASO). He continued to serve in this position when the group was re-formed as Central Area in March 1940. Posted to Western Australia to take command of RAAF Station Pearce in August, he was promoted to temporary group captain on 1 September 1940. He became Senior Administration Officer at the newly established Western Area, Perth, in January the following year. In September 1942, Charlesworth took over No. 2 Bombing and Gunnery School in Sale, Victoria. He handed over to Group Captain Charles "Moth" Eaton in August 1943, before briefly taking charge of RAAF Headquarters Forward Echelon in Brisbane. Charlesworth was appointed Air Officer Commanding (AOC) Eastern Area, headquartered at Bradfield Park, Sydney, in December 1943. Eastern Area was responsible for maritime patrol and anti-submarine warfare off the coast of New South Wales and southern Queensland. Japanese submarine activity had decreased in the months prior to Charlesworth taking command, and he was concerned that Allied ships were becoming complacent. He observed "a general slackening off in procedure; ships are seldom where they should be, and a minority of merchant ships identify themselves to aircraft". The RAAF's patrols had also settled into a predictable pattern that would have been easy for an observant submarine captain to avoid.
