Eric IX of Sweden, (Swedish: "Erik Jedvardsson; Erik den helige"; died 18 May 1160), also called Eric the Lawgiver, Erik the Saint, Eric the Holy, and, in Sweden, Sankt Erik, meaning Saint Eric, was a Swedish king c. 1156-60.
 No historical records of Eric have survived, and all information about him is based on later legends that were aimed at having him established as a saint.
 The "Roman Martyrology" of the Catholic Church names him as a saint memorialized on 18 May.
 He is the ancestor of the House of Eric which ruled Sweden with interruptions from c. 1156 to 1250.
Daniel Ernest Henning, (born June 21, 1942) is a former American football player and coach.
 A quarterback, he played college football at the College of William & Mary and professional football in 1966 for the San Diego Chargers of the American Football League (AFL).
 Henning served as a head coach in the National Football League (NFL) for the Atlanta Falcons (1983–1986) and the Chargers (1989–1991).
 He was the head football coach at Boston College from 1994 to 1996.
 Henning then returned to the NFL as an offensive coordinator for the Buffalo Bills in 1997.
 After Hall of Fame coach Marv Levy retired, reportedly partially due to his reluctance to fire Henning, Henning left Buffalo.
The Hats (Swedish: "Hattarna" ) were a Swedish political faction active during the Age of Liberty (1719–1772).
 Their name derives from the tricorne hat worn by officers and gentlemen.
 They vied for power with the opposing Caps party.
 The Hats, who ruled Sweden from 1738 to 1765, advocated an alliance with France and an assertive foreign policy, especially towards Russia.
 During their tenure, they involved Sweden in two expensive and disastrous wars, in the 1740s and 1750s.
Henning Podebusk or Putbus (before 1350 –  1388 ) was a German-Slavic statesman, the last drost of Denmark.
 He served under King Valdemar IV, King Oluf II, and Queen Margaret I, and he was the "de facto" ruler of Denmark from 1368 to 1370.
 Podebusk, whose personal character is unknown, is now considered one of the most important Danish statesmen of the Middle Ages.
 His political views seem to have been just as cynical and power-centred as that of his royal masters, but perhaps he was an even better diplomat.
 By his death the office of drost was abolished, probably because he had shown how powerful it might be.
An interregnum regent is a person who rules in the place of the rightful heir until he or she reaches the age of maturity.
 In ancient Egypt, the tradition was established during Dynasty One during the reign of Merneith, who acted as interregnum regent for her son, Den, who later ruled as Pharaoh.
 That this queen ruled for a period of time is confirmed from the Palermo Stone, on which the early dynastic kings are named.
This is a list of Queens who have ruled as Queen in many countries (Separate queens for separate countries).
 Included also are Pharaohs and Empresses.
 If the Queen ruled as a regent this is indicated by "(regent)" following the name.
 Where a queen had no powers but only the title "(titular)" is added.

Erato also known as Queen Erato (flourished second half of 1st century BC & first half of 1st century, died sometime after 12) was a Princess of the Kingdom of Armenia and member of the Artaxiad Dynasty.
 She served as a Roman Client Queen of Armenia from 10 BC until 2 BC with her brother-husband King Tigranes IV.
 After a number of years living in political exile, she co-ruled with her distant paternal relative the Herodian Prince Tigranes V as Roman Client Monarchs of Armenia from 6 until 12.
 She as Armenian Queen ruled on the Armenian throne twice.
 As a Queen of Armenia, she can be viewed as one of the last hereditary rulers of her nation.
The House of Holstein-Gottorp, a cadet branch of the Oldenburg dynasty, ruled Sweden from 1751 until 1818, and Norway from 1814 to 1818.
Margaret I (Danish: "Margrete Valdemarsdatter" , Norwegian: "Margrete Valdemarsdatter" , Swedish: "Margareta Valdemarsdotter" , Icelandic: "Margrét Valdimarsdóttir" ; 1353 – 28 October 1412), was queen consort of Norway 1363-1380 and Sweden 1363-1364, and later ruler in her own right of Denmark, Norway and Sweden, from which later period there are ambiguities regarding her specific titles.
 She was the founder of the Kalmar Union, which spanned Scandinavia for over a century.
 Margaret was known as a wise, energetic and capable leader, earning the nickname "Semiramis of the North", or "the Lady King".
 Though the latter was a derisive nickname invented by her rival Albert of Mecklenburg, it became widely used in recognition of her capabilities.
