Luxembourg, officially the Grand Duchy of Luxembourg, is a landlocked country in western Europe. It is bordered by Belgium to the west and north, Germany to the east, and France to the south. Its capital, Luxembourg City, is, together with Brussels and Strasbourg, one of the three official capitals of the European Union and the seat of the European Court of Justice, the highest juridical authority in the EU. Its culture, people and languages are highly intertwined with its neighbours, making it essentially a mixture of French and Germanic cultures. This is emphasised by the three official languages, Luxembourgish, French, and German. The repeated invasions by Germany, especially in World War II, resulted in the country's strong will for mediation between France and Germany and, among other things, led to the foundation of the European Union.

With an area of , it is one of the smallest sovereign states in Europe, about the same size as the US state of Rhode Island or the English county of Northamptonshire. In 2016, Luxembourg had a population of 576 249, which makes it one of the least-populous countries in Europe, but by far the one with the highest population growth rate. As a representative democracy with a constitutional monarch, it is headed by a Grand Duke, Henri, Grand Duke of Luxembourg, and is the world's only remaining grand duchy. Luxembourg is a developed country, with an advanced economy and one of the world's highest GDP (PPP) per capita. The City of Luxembourg with its old quarters and fortifications was declared a UNESCO World Heritage Site in 1994 due to the exceptional preservation of the vast fortifications and the old city.
