 It administered the Crown of Aragon, which was composed of the Kingdom of Aragon, Principality of Catalonia (including Roussillon until 1659), Kingdom of Valencia, Kingdom of Mallorca, as well as Aragon's Italian possessions (Kingdom of Sicily, Naples, and Sardinia) until the 1558 creation of the Council of Italia.

A water ball or water walking ball is a large inflatable sphere that allows a person inside it to walk across the surface of a body of water.
 The giant ball is usually two metres in diameter and has a zippered entrance to allow for easy entry and exit.
 The water ball is similar to the zorb, but it has only one layer and is designed for water travel rather than down-hill rolling.
 In the United Kingdom, the balls have been used at swimming pools, marinas and lakes in an effort to keep children fit.
Airlangga (also spelled Erlangga), regnal name Rakai Halu Sri Lokeswara Dharmawangsa Airlangga Anantawikramottunggadewa (born 991 in Bali, Indonesia – died 1049 in Java), was the only raja of the Kingdom of Kahuripan.
 The Kingdom was built from the territory of the Kingdom of Medang after Medang was sacked by king Wurawari of Lwaram.
 He gradually gained support, won back the kingdom once ruled by his uncle, and went on to become one of Java's most notable kings.
 "Airlangga" literally means "jumping water", thus his name means "he who crossed the water", described his life story; born in the court of Bali and during his youth crossed the Bali Strait to stay in Java and later ruled the kingdom in East Java.
 He belongs to both Isyana and Warmadewa lineages.
Ragnall mac Somairle (also known in Gaelic as "Raghnall", "Raonall", "Raonull"; in English as "Ranald", "Reginald"; in Latin as "Reginaldus"; and in Old Norse as "Rögnvaldr", "Røgnvaldr", "Rǫgnvaldr"; died 1191/1192–c. 1210 /1227) was a significant late twelfth century magnate, seated on the western seaboard of Scotland.
 He was probably a younger son of Somairle mac Gilla Brigte, Lord of Argyll and his wife, Ragnhildr, daughter of Óláfr Guðrøðarson, King of the Isles.
 The twelfth-century Kingdom of the Isles, ruled by Ragnall's father and maternal-grandfather, existed within a hybrid Norse-Gaelic milieu, which bordered an ever strengthening and consolidating Kingdom of Scots.
Rǫgnvaldr Guðrøðarson (died 14 February 1229) ruled as King of the Isles from 1187 to 1226.
 He was the eldest son of Guðrøðr Óláfsson, King of Dublin and the Isles.
 Although the latter may have intended for his younger son, Óláfr, to succeed to the kingship, the Islesmen chose Rǫgnvaldr, who was likely Óláfr's half-brother.
 Rǫgnvaldr went on to rule the Kingdom of the Isles for almost forty years before losing control to Óláfr.
The Water Act 1989 (1989 c.15) is an Act of the Parliament of the United Kingdom that reorganised the bodies responsible for all aspects of water within England and Wales.
 Whereas previous legislation, particularly the Water Act 1973, had focused on providing a single unifying body with responsibility for all water-related function within a river basin or series of river basins, this legislation divided those functions up again, with water supply, sewerage and sewage disposal being controlled by private companies, and the river management, land drainage and pollution functions becoming the responsibility of the National Rivers Authority.
The Kingdom of the Isles comprised the Hebrides, the islands of the Firth of Clyde and the Isle of Man from the 9th to the 13th centuries AD.
 The islands were known to the Norse as the "Suðreyjar", or "Southern Isles" as distinct from the "Norðreyjar" or Northern Isles of Orkney and Shetland.
 The historical record is incomplete, and the kingdom was not a continuous entity throughout the entire period.
 The islands concerned are sometimes referred to as the Kingdom of Mann and the Isles, although only some of the later rulers claimed that title.
 At times the rulers were independent of external control, although for much of the period they had overlords in Norway, Ireland, England, Scotland or Orkney.
 At times there also appear to have been competing claims for all or parts of the territory.
 The islands involved have a total land area of over 8300 km2 and extend for more than 500 km from north to south.
