On this day in 1794 Denmark and Sweden formed neutrality compact.
A neutral power in a particular war is a sovereign state which officially declares itself to be neutral towards the belligerents. A non-belligerent state does not need to be neutral. The rights and duties of a neutral power are defined in Sections 5 and 13 of the Hague Convention of 1907.
A permanently neutral power is a sovereign state which is bound by international treaty to be neutral towards the belligerents of all future wars. An example of a permanently neutral power is Switzerland. The concept of neutrality in war is narrowly defined and puts specific constraints on the neutral party in return for the internationally recognised right to remain neutral.
Belligerents may not invade neutral territory, and a neutral power’s resisting any such attempt does not compromise its neutrality.
A neutral power must intern belligerent troops who reach its territory, but not escaped prisoners of war. Belligerent armies may not recruit neutral citizens, but they may go abroad to enlist. Belligerent armies’ personnel and material may not be transported across neutral territory, but the wounded may be. A neutral power may supply communication facilities to belligerents, but not war material, although it need not prevent export of such material.
