Abstract EN:

The treaty of london of 1867 confers to the grand-duchy of luxembourg the statute of a neutrality collectively guaranteed by the great powers, what did not hinder germany to violage the constitutional neutrality of luxembourg and to occupy the country during the first and second world wars. The government in exil in london placed himself on the side of the allied countries. Luxembourg belongs to the founding members of the united nations charta. In the grand-duchy the compulsery military service is introduced and by a modification of the constitution the neutrality is abolished. This opens the way to the adhesion of luxembourg to the treaty of brussels of 1948. At economic level luxembourg becomes a members of the organization for economic cooperation in europe and is in a position to take benefit from the advantages of the marshallplan. Luxembourg is a member of the north atlantic treaty, treaty where the signataries of the brussels treaty are joined by seven more states. These countries agree that every armed attack against one or more of them occuring in europe or in northern america will be considered as an attack directed against all parties. At bilateral level the grand-duchy strengthens this stipulations by an agreement on mutual defence with the united states.
