Question: When did the Sassanids replace the Parthians? Passage: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.

Question: How many years did Justin's father's party have power before being defeated in the 1979 election? Passage:Trudeau lived at 24 Sussex Drive, Ottawa, the official residence of Canada's prime minister, from his birth until his father's government was defeated in the federal election on May 22, 1979. The Trudeaus were expected to move into the residence of the Leader of the Official Opposition, Stornoway, at 541 Acacia Avenue in Rockcliffe Park, but because of flooding in the basement, prime minister Joe Clark offered them Harrington Lake, the prime minister's official country retreat in Gatineau Park, with the expectation they would move into Stornoway at the start of July. However, the repairs were not complete so Pierre Trudeau took a prolonged vacation with his sons to the Nova Scotia summer home of his friend, MP Don Johnston, and later sent his sons to stay with their maternal grandparents in North Vancouver for the rest of the summer while he slept at his friend's Ottawa apartment. Justin and his brothers returned to Ottawa for the start of the school year, but lived only on the top floor of Stornoway while repairs continued on the bottom floor. His mother purchased and moved into a new home nearby at 95 Queen Victoria Avenue in Ottawa's New Edinburgh in September 1979. The Trudeaus returned to the prime minister's official residence in February 1980 after the election that returned his father to the Prime Minister's Office.
