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, together with Brussels and Strasbourg, is one of the three official capitals of the European Union and the seat of the European Court of Justice, the highest judicial 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.

With an area of 2,586 square kilometres (998 sq mi), 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 2019, Luxembourg had a population of 613.894, which makes it one of the least-populous countries in Europe, but by far the one with the highest population growth rate. Foreigners account for nearly half of Luxembourg’s population. As a representative democracy with a constitutional monarch, it is headed by Grand Duke Henri 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.
