A realm ( /ˈrɛlm/) is a community or territory over which a sovereign rules; it is commonly used to describe a kingdom or other monarchical or dynastic state.

The Old French word reaume, modern French royaume, was the word first adopted in English; the fixed modern spelling does not appear until the beginning of the 17th century. The word supposedly derives from medieval Latin regalimen, from regalis, of or belonging to a rex, (king).

"Realm" is particularly used for those states whose name includes the word kingdom (for example, the United Kingdom), to avoid clumsy repetition of the word in a sentence (for example, "The Queen's realm, the United Kingdom..."). It is also useful to describe those countries whose monarchs are called something other than "king" or "queen"; for example, the Grand Duchy of Luxembourg is a realm but not a kingdom since its monarch holds the title Grand Duke rather than King.

"Realm" is also frequently used to refer to territories that are "under" a monarch, yet are not a physical part of his or her "kingdom" (e.g. the Realm of Sweden, or to Holstein, which until the Second War of Schleswig was an important part of the Danish King's realm stretching to the border of Hamburg, although not a part of the Danish Kingdom). Similarly, the Cook Islands, Niue, and Tokelau are considered parts of the Realm of New Zealand, although they are not part of New Zealand proper. Likewise, the Faroe Islands and Greenland remain parts of the Danish Realm.

Michael Joseph Jackson (August 29, 1958 – June 25, 2009) was an American recording artist, entertainer, and businessman. Often referred to as the King of Pop, or by his initials MJ, Jackson is recognized as the most successful entertainer of all time by Guinness World Records. His contribution to music, dance, and fashion, along with a much-publicized personal life, made him a global figure in popular culture for over four decades. The seventh child of the Jackson family, he debuted on the professional music scene along with his brothers as a member of The Jackson 5 in 1964, and began his solo career in 1971.

In the early 1980s, Jackson became a dominant figure in popular music. The music videos for his songs, including those of "Beat It", "Billie Jean", and "Thriller", were credited with transforming the medium into an art form and a promotional tool, and the popularity of these videos helped to bring the relatively new television channel MTV to fame. Videos such as "Black or White" and "Scream" made him a staple on MTV in the 1990s. Through stage performances and music videos, Jackson popularized a number of complicated dance techniques, such as the robot and the moonwalk, to which he gave the name. His distinctive musical sound and vocal style influenced numerous hip hop, post-disco, contemporary R&B, pop and rock artists.
