Question:
The Macedonians (Greek: Makedones, Makedones) were an ancient tribe that lived on the alluvial plain around the rivers Haliacmon and lower Axios in the northeastern part of mainland Greece. Essentially an ancient Greek people, they gradually expanded from their homeland along the Haliacmon valley on the northern edge of the Greek world, absorbing or driving out neighbouring non-Greek tribes, primarily Thracian and Illyrian. They spoke Ancient Macedonian, a language closely related to Ancient Greek, perhaps a dialect, although the prestige language of the region was at first Attic and then Koine Greek. Their religious beliefs mirrored those of other Greeks, following the main deities of the Greek pantheon, although the Macedonians continued Archaic burial practices that had ceased in other parts of Greece after the 6th century BC.
Both Strabo and Thucydides said that Emathia and Pieria were mostly occupied by Thracians (Pieres, Paeonians) and Bottiaeans, as well as some Illyrian and Epirote tribes. Herodotus states that the Bryges were cohabitants with the Macedonians before their mass migration to Anatolia. If a group of ethnically definable Macedonian tribes were living in the Pierian highlands prior to their expansion, the first conquest was of the Pierian piedmont and coastal plain, including Vergina. The tribes may have launched their expansion from a base near Mount Bermion, according to Herodotus. Thucydides describes the Macedonian expansion specifically as a process of conquest led by the Argeads: But the country along the sea which is now called Macedonia, was first acquired and made a kingdom by Alexander [I], father of Perdiccas [II] and his forefathers, who were originally Temenidae from Argos. They defeated and expelled from Pieria the Pierians ... and also expelled the Bottiaeans from Bottiaea ... they acquired as well a narrow strip of Paeonia extending along the Axios river from the interior to Pella and the sea. Beyond the Axios they possess the territory as far as the Strymon called Mygdonia, having driven out the Edoni. Moreover, they expelled from the district now called Eordaea the Eordi ... The Macedonians also made themselves rulers of certain places ... namely Anthemus, Grestonia, and a large part of Macedonia proper. Thucydides's account gives a geographical overview of Macedonian possessions at the time of Alexander I's rule. To reconstruct a chronology of the expansion by Alexander I's predecessors is more difficult, but generally, three stages have been proposed from Thucydides' reading. The initial and most important conquest was of Pieria and Bottiaea, including the locations of Pydna and Dium. The second stage consolidated rule in Pieria and Bottiaea, captured Methone and Pella, and extended rule over Eordaea and Almopia. According to Hammond, the third stage occurred after 550 BC, when the Macedonians gained control over Mygdonia, Edonis, lower Paeonia, Bisaltia and Crestonia. However, the second stage might have occurred as late as 520 BC; and the third stage probably did not occur until after 479 BC, when the Macedonians capitalized on the weakened Paeonian state after the Persian withdrawal from Macedon and the rest of their mainland European territories. Whatever the case, Thucydides' account of the Macedonian state describes its accumulated territorial extent by the rule of Perdiccas II, Alexander I's son. Hammond has said that the early stages of Macedonian expansion were militaristic, subduing or expunging populations from a large and varied area. Pastoralism and highland living could not support a very concentrated settlement density, forcing pastoralist tribes to search for more arable lowlands suitable for agriculture.

Question:
Therapy? are an alternative metal band from Northern Ireland. The band was formed in 1989 by guitarist-vocalist Andy Cairns from Ballyclare and drummer-vocalist Fyfe Ewing from Larne, Northern Ireland. The band initially recorded their first demo with Cairns filling in on bass guitar. To complete the lineup, the band recruited Larne bassist Michael McKeegan.
If there was one true "breakthrough" year in the band's history, it would almost certainly be 1993. The release of the Shortsharpshock EP catapulted Therapy? into the Top 40, peaking at nine, featuring the lead track Screamager. The single led to the first of several appearances on the venerable UK music show Top of the Pops. Two more UK Top 40 EPs Face the Strange and Opal Mantra followed, as the band toured heavily on the European festival circuit, made two separate jaunts to the United States in support of Kings X initially, and then both Helmet and The Jesus Lizard, and played their debut shows in Japan. Compilations of the three EP's were released in the U.S. and Japan (Hats Off to the Insane), and in Europe (Born in a Crash). 1994 saw the release of the commercially successful Troublegum album in February which earned the band appearances at a string of rock and indie festivals, including Reading (third consecutive appearance), Donington and Phoenix in the UK alone, as well as a clutch of Top 40 singles. It achieved a string of nominations in end-of-year polls, including a Mercury Music Prize nomination, and success at the Kerrang! Awards. With impatience mounting for a new album, Infernal Love was released in June 1995. This time, the press reaction was lukewarm. The band had attempted to create a "cinematic" record with Belfast DJ David Holmes employed to link each track with "insanity", but in the eyes of many, had produced a disjointed piece over-subscribed with ballads. Despite a second consecutive Donington appearance at Metallica's request, and singles Stories and Loose charting in the UK earlier in the year, it was clear that Therapy? had changed direction. Although the string laden single Diane was a Top 10 hit in 15 European countries later in the year, much of the early momentum had gone.
