Anglo-German Naval Agreement

The Anglo-German Naval Agreement (A.G.N.A) of June 18, 1935 was a bilateral agreement between the United Kingdom and German Reich regulating the size of the Kriegsmarine in relation to the Royal Navy. The A.G.N.A fixed a ratio whereby the total tonnage of the Kriegsmarine was to be 35% of the total tonnage of the Royal Navy on a permanent basis. It was registered in League of Nations Treaty Series on July 12, 1935. The agreement was renounced by Adolf Hitler on April 28, 1939.

The A.G.N.A was an ambitious attempt on the part of both London and Berlin to reach better relations, but it ultimately foundered because of conflicting expectations between the two states. For the Germans, the A.G.N.A. was intended to mark the beginning of an Anglo-German alliance against France and the Soviet Union, whereas for the British, the A.G.N.A. was to be the beginning of a series of arms limitation agreements that were made to limit German expansionism. The A.G.N.A was highly controversial, both at the time and since, because the 35:100 tonnage ratio allowed Germany the right to build a Navy beyond the limits set by the Treaty of Versailles, and the British had made the agreement without consulting France or Italy first.
