The vast Seleucid Empire was, like Egypt, mostly dominated by a Greco-Macedonian political elite. The Greek population of the cities who formed the dominant elite were reinforced by emigration from Greece. These cities included newly founded colonies such as Antioch, the other cities of the Syrian tetrapolis, Seleucia (north of Babylon) and Dura-Europos on the Euphrates. These cities retained traditional Greek city state institutions such as assemblies, councils and elected magistrates, but this was a facade for they were always controlled by the royal Seleucid officials. Apart from these cities, there were also a large number of Seleucid garrisons (choria), military colonies (katoikiai) and Greek villages (komai) which the Seleucids planted throughout the empire to cement their rule. This 'Greco-Macedonian' population (which also included the sons of settlers who had married local women) could make up a phalanx of 35,000 men (out of a total Seleucid army of 80,000) during the reign of Antiochos III. The rest of the army was made up of native troops. Antiochus III the great conducted several vigorous campaigns to retake all the lost provinces of the empire since the death of Seleucus I. After being defeated by Ptolemy IV's forces at Raphia (217), Antiochus III led a long campaign to the east to subdue the far eastern breakaway provinces (212-205) including Bactria, Parthia, Ariana, Sogdiana, Gedrosia and Drangiana. He was successful, bringing back most of these provinces into at least nominal vassalage and receiving tribute from their rulers. After the death of Ptolemy IV (204), Antiochus took advantage of the weakness of Egypt to conquer Coele-Syria in the fifth Syrian war (202-195). He then began expanding his influence into Pergamene territory in Asia and crossed into Europe, fortifying Lysimachia on the hellespont, but his expansion into Anatolia and Greece was abruptly halted after a decisive defeat at the Battle of Magnesia (190 BCE). In the Treaty of Apamea which ended the war, Antiochus lost all of his territories in Anatolia west of the Taurus and was forced to pay a large indemnity of 15,000 talents.

In 1978, the band released Jazz, which reached number two in the UK and number six on the Billboard 200 in the US. The album included the hit singles "Fat Bottomed Girls" and "Bicycle Race" on a double-sided record. Queen rented Wimbledon Stadium for a day to shoot the video, with 65 naked female models hired to stage a nude bicycle race. Reviews of the album in recent years have been more favourable. Another notable track from Jazz, "Don't Stop Me Now", provides another example of the band's exuberant vocal harmonies.
Queen rented what venue for a music video in 1978?

One of John's principal challenges was acquiring the large sums of money needed for his proposed campaigns to reclaim Normandy. The Angevin kings had three main sources of income available to them, namely revenue from their personal lands, or demesne; money raised through their rights as a feudal lord; and revenue from taxation. Revenue from the royal demesne was inflexible and had been diminishing slowly since the Norman conquest. Matters were not helped by Richard's sale of many royal properties in 1189, and taxation played a much smaller role in royal income than in later centuries. English kings had widespread feudal rights which could be used to generate income, including the scutage system, in which feudal military service was avoided by a cash payment to the king. He derived income from fines, court fees and the sale of charters and other privileges. John intensified his efforts to maximise all possible sources of income, to the extent that he has been described as "avaricious, miserly, extortionate and moneyminded". John also used revenue generation as a way of exerting political control over the barons: debts owed to the crown by the king's favoured supporters might be forgiven; collection of those owed by enemies was more stringently enforced.
