The Tulip Festival is held in Albany, New York every spring at Washington Park.
 It stems from when Mayor Erastus Corning 2nd got a city ordinance passed declaring the tulip as Albany's official flower on July 1, 1948.
 In addition, he sent a request to Queen Wilhelmina of the Netherlands to name a variety as Albany's tulip.
 On July 11, 1948 her reply was "Her Majesty gladly accepts the invitation to designate a tulip as the official flower of Albany."
 She picked the variety "Orange Wonder", an 18-inch tall tulip that is orange-shaded with a scarlet toward the center, it is a slow-grower and relatively rare.
 The first Tulip Fest was celebrated the next year on May 14, 1949 with opening ceremonies still carried on today as tradition, such as the sweeping of State Street and the crowning of a Tulip Queen.
 In 1997 to commemorate the 50th anniversary of the festival the state of New York designated Albany as the "I Love New York Spring Destination".
 Also for the 50th anniversary a descendant variety of the "Wonder Orange" tulip was found in the Netherlands, and the new variety was named "City of Albany".
 The African-American tradition of Pinksterfest, whose origins are traced back even further to Dutch festivities, was later incorporated into the Tulip Fest.
 Since 1998 the Tulip Fest has included the Mother of the Year award.
Orangism was a political current in what is now Belgium that supported its inclusion in the short-lived United Kingdom of the Netherlands (1815–1830).
 After the secession of Belgium in 1830, Orangist sentiment in Flanders and Wallonia for a time sought a restoration of the United Kingdom of the Netherlands.
 It was a movement directed by William I of the Netherlands as part of his "Volhardingspolitiek" and containing most of the Belgian elites (nobility, industrials).
 Some of the most prominent Flemish Orangists were Jan Frans Willems and Hippolyte Metdepenningen.
 Although refusing the partake in parliamentary elections as they deemed the Belgian institutions as illegitimate, the Orangists did take part in local elections (province and municipal) from which they activated against the new Belgian state through political actions and an activist press.
 At least three Orangist coups were foiled during the 1830s.
 Although losing Dutch financial and political support after the Treaty of London (1839) and William I's abdication (1840), the weakening Belgian Orangism survived well into the 1850s, strongly opposing the Belgian Revolution and rallying against independence.
Petronilla (29 June/11 August 1136 – 15 October 1173), whose name is also spelled Petronila or Petronella (Aragonese "Peyronela" or "Payronella", and Catalan: "Peronella" ), was the Queen of Aragon from the abdication of her father in 1137 until her own abdication in 1164.
 She was the daughter and successor of Ramiro II by his queen, Agnes.
 She was the last ruling member of the Jiménez dynasty in Aragon, and by marriage brought the throne to the House of Barcelona.
Wilhelmina (] ; Wilhelmina Helena Pauline Maria; 31 August 1880 – 28 November 1962) was Queen of the Netherlands from 1890 until her abdication in 1948.
Queen's Tower (Greek: Πύργος Βασιλίσσης , "Pyrgos Vasilissis") is a former royal estate near Athens, Greece.
 The estate, consisting of 200 hectares (494 acres), was purchased by King Otto, the first king of modern Greece.
 He built there a small neogothic castle for his wife, Queen Amalia.
 The architecture resembles Hohenschwangau castle in Bavaria, built for Maximilian II of Bavaria, the brother of King Otto.
 As the castle is only one tower, it is called the Queen's Tower.
 After the abdication of King Otto, the estate was sold to the Serpieri family, who still own it.
 They have a dairy farm and wineyard on the estate.
 The wines bottled on the estate are called "Tour la Reine" (French for Queen's Tower).
Jane Loftus, Marchioness of Ely ("née" Hope-Vere; 3 December 1821 – 11 June 1890) was an English lady of the bedchamber and a close friend of Queen Victoria.
 Her parents were James Hope-Vere and Lady Elizabeth Hay, and through her mother she was a cousin of Arthur Wellesley, the first Duke of Wellington.
 After her marriage to John Loftus, the third Marquess of Ely, she developed friendships with Queen Sophie of the Netherlands and the Empress Eugénie.
 Jane arrived at court as a Lady of the Bedchamber in 1851, and despite her own nervousness and lack of discretion, she became a close companion of Queen Victoria until her resignation in 1889.
 Her service was marred by her constant illnesses and fear of the Queen, but she proved a loyal and devoted servant, deferring to her royal mistress in all matters.
 Jane died on June 1, 1890 and is buried at Kensal Green cemetery in London.
Queen Juliana was the Queen of the Kingdom of the Netherlands from 4 September 1948 until her abdication on 30 April 1980.
 During her reign she was served by 36 Prime Ministers: 10 in the Netherlands, 15 in the Netherlands Antilles, and 11 in Suriname.
Juliana (] ; Juliana Louise Emma Marie Wilhelmina; 30 April 1909 – 20 March 2004) was Queen of the Netherlands from 1948 until her abdication in 1980.
Philippe (] , French: "Philippe Léopold Louis Marie" , Dutch: "Filip Leopold Lodewijk Maria" , German: "Philipp Leopold Ludwig Maria" ; born 15 April 1960) is the seventh King of the Belgians, having ascended the throne on 21 July 2013, following his father's abdication.
 He is the eldest child of King Albert II, whom he succeeded upon Albert's abdication for health reasons, and Queen Paola.
 He married Countess Mathilde d'Udekem d'Acoz (now Queen Mathilde), with whom he has four children.
 King Philippe's elder daughter, Princess Elisabeth, is first in the line of succession.
The monarchy of the Netherlands is constitutional and as such, the role and position of the monarch are defined and limited by the constitution of the Netherlands.
 Consequently, a fairly large portion of the Dutch constitution is devoted to the monarch; roughly a third of the constitution describes the succession, mechanisms of accession and abdication to the throne, the roles and responsibilities of the monarch and the formalities of communication between the States-General of the Netherlands and the role of the monarch in the creation of laws.
