Grand Duchy of Luxembourg
Luxembourg, 1815 to today. Draft, not yet reviewed
After the defeat of Napoleon in 1815, the Congress of Vienna decided to restore the Duchy of Luxembourg. In the 1839 Treaty of London, the territory was reduced by more than half, thereby giving Luxembourg its modern-day borders. In 1890, due to a succession crisis, the Dutch monarchy ceased to hold the title Grand-Duke of Luxembourg. In the 1950s, Luxembourg became one of the six founding countries of the European Communities.
Seat of power: Luxembourg
Rulers
William I of the Netherlands
Grand Duke of Luxembourg, 1815–1840
In 1815, William raised the Netherlands to a kingdom and concurrently became the grand duke of Luxembourg. From 1816 to 1830, William I ignored the Duchy's sovereignty, treating Luxembourg as a conquered nation while subjecting Luxembourg to high taxes.

William II of the Netherlands
Grand Duke of Luxembourg, 1840–1849
William II was King of the Netherlands, Grand Duke of Luxembourg, and Duke of Limburg from 1840 until his death. In Luxembourg, he founded the Order of the Oak Crown on 29 December 1841. During his reign, the Netherlands became a parliamentary democracy with the new constitution of 1848.

William III of the Netherlands
Grand Duke of Luxembourg, 1849–1890
William III was King of the Netherlands and Grand Duke of Luxembourg from 1849 until his death in 1890. In what became known as the "Luxembourg Coup of 1856", William unilaterally instituted a new, reactionary constitution for Luxembourg, which he ruled personally, separate from the Dutch crown. In 1867, France offered to buy Luxembourg, leading to the Luxembourg Crisis, which almost precipitated war between Prussia and France.

Adolphe, Grand Duke of Luxembourg
Grand Duke of Luxembourg, 1890–1905
Adolphe was already 73 years old by this time and knew little of Luxembourgish politics. He mostly abstained from day-to-day governing; Prime Minister Paul Eyschen, in office since 1888, took care of the affairs of state. This established a convention that the monarch would remain absent from the politics of the day, despite being vested with considerable reserve powers on paper.

William IV, Grand Duke of Luxembourg
Grand Duke of Luxembourg, 1905–1912
William was Grand Duke of Luxembourg from 17 November 1905 until his death in 1912. Like his father, William did not participate in politics, despite being vested with considerable power by the Constitution.

Marie-Adélaïde, Grand Duchess of Luxembourg
Grand Duke of Luxembourg, 1912–1919
Marie-Adélaïde was deeply interested in politics and took an active part in the government and the political life of the Grand Duchy. On the day of her accession to the throne, 25 February 1912, she refused to sign a new law reducing the role of Catholic priests within the education system. In late 1915 the Grand Duchess caused controversy by dissolving the Chamber of Deputies to solve the deadlock faced by the Loutsch Ministry, which was composed of Party of the Right members and did not have a majority in the Chamber.

Charlotte, Grand Duchess of Luxembourg
Grand Duke of Luxembourg, 1919–1964
In a referendum on 28 September 1919, 77.8% of the Luxembourgish people voted for the continuation of the monarchy with Grand Duchess Charlotte as head of state. In the new constitution, the powers of the monarch were severely restricted, thus codifying actual practices dating from the end of the personal union with the Netherlands in 1890. By 29 August 1940 Grand Duchess Charlotte was in London where she began to make supportive broadcasts to her homeland using the BBC.

Jean, Grand Duke of Luxembourg
Grand Duke of Luxembourg, 1964–2000
Jean was Grand Duke of Luxembourg from 1964 until his abdication in 2000. During his reign, Grand Duke Jean saw Luxembourg transformed from a minor industrial contributor into an international financial centre. The Grand Duke's reign was one of the most prosperous periods in the history of the Grand Duchy of Luxembourg.

Henri I, Grand Duke of Luxembourg
Grand Duke of Luxembourg, 2000–2025
Henri reigned as Grand Duke of Luxembourg from 2000 until his abdication in 2025. Henri's role was largely ceremonial as a constitutional monarch. Henri sparked a minor constitutional crisis in 2008 when he refused to grant royal assent to a new euthanasia law, resulting in the requirement for laws to receive his assent being abolished.

Guillaume V, Grand Duke of Luxembourg
Grand Duke of Luxembourg, 2025 to today
Guillaume V is Grand Duke of Luxembourg, reigning since 3 October 2025. He acceded to the throne upon the abdication of his father. On 8 October 2024, Guillaume was appointed as lieutenant-representative (regent), and in this role he assumed a number of his father's constitutional powers, such as the swearing in of ambassadors and the signing of Grand Ducal Decrees.

Culture
- The Old City of Luxembourg is part of the UNESCO World Heritage List, on account of the historical importance of its fortifications.
- The country has produced some internationally known artists, including the painters Théo Kerg, Joseph Kutter and Michel Majerus, and photographer Edward Steichen, whose The Family of Man exhibition has been placed on UNESCO's Memory of the World register, and is now permanently housed in Clervaux.
- Luxembourg has won the Eurovision Song Contest a total of five times, in 1961, 1965, 1972, 1973 and 1983. Only nine of its 38 entries before 2024, and none of its five winning entries, were performed by Luxembourgish artists.
- Luxembourg cuisine reflects its position on the border between the Latin and Germanic worlds, being heavily influenced by the cuisines of neighbouring France and Germany. More recently, it has been enriched by its many Italian and Portuguese immigrants.
