The agreement was a change for both countries. France had been isolated from other European powers, notably following the efforts of German Chancellor Otto von Bismarck to distance France from its potential allies, because it was thought that France could avenge its defeat in the Franco-German war of 1870/71. For nearly a century, Britain had pursued a policy of „splendid isolation“ on the European continent and had only engaged in continental affairs when it was deemed necessary to protect British interests and maintain the continental balance of power. The situation changed for both countries in the last decade of the 19th century.  On April 8, 1904, a series of agreements were signed between England and France, known as the Cordial Agreement. Following lengthy discussions between the two former rivals, the agreements officially marked the end of hostilities that erupted temporarily across the Channel, elucidating more immediate issues of imperial expansion and (re) distributed power in contested places, including Egypt, Morocco, Senegal and Nigeria. Historians have tended to focus on the imperial conflicts that led to the signing of the agreements, including in Egypt and Africa, as well as the legacy of the Agreement in the 20th century. The manner in which the 1904 agreements were used to formalize the more informal cordial agreement (French for „hot agreement“), which existed between England and France in the 19th century and which paved the way for the British and French to ally themselves against German aggression during the First World War. With the Cordial Agreement, the two powers reduced the virtual isolation in which they had retreated – France involuntarily, Britain complacent – while they observed each other on African issues. Britain had no major ally of power except Japan (1902) and it would be pointless for war to break out in European waters; France had nothing but Russia, which was soon discredited in the Russo-Japanese War of 1904/05. The agreement was upsetting for Germany, whose policy has long insisted on relying on Franco-British antagonism. A German attempt to control the French in Morocco in 1905 (the Tangier incident or the First Moroccan Crisis) and thus to thwart the Agreement served only to strengthen them.
Military talks were quickly initiated between the French and British staffs. Franco-British solidarity was confirmed at the Algeciras conference (1906) and reaffirmed during the Second Moroccan Crisis (1911).  At the beginning of the 20th century, after a period of tension between the two countries, Britain and France agreed to settle a series of still-open colonial disputes. On April 8, 1904, four agreements were concluded in London, which founded the Anglo-French Agreement or the Cordial Agreement. An agreement, it should be noted, is an „understanding“ – not an alliance agreement. These agreements were: this agreement is indeed on all lines with turbulent conditions that can lead to great difficulties in the future. They will receive not only financial compensation, but also territorial transfers in The Gambia and Niger.
