Britain followed a policy of ‘Splendid Isolation’ from European affairs, because:
They wanted to focus on maintaining and building their Empire
It avoided rivalry with powerful nations, a concern that grew with the creation of Germany
Britain felt self-sufficient economically due to the industrial revolution, so needed no economic allies
French politicians were too distracted by the problems in the Third Republic to focus much on foreign policy
There was a stronger rivalry with the German after the Prussian-Franco War which over-rode all other rivalries
The German policy of Weltpolitik led to Germany trying to assert themselves over Britain in Africa, leading to Anglo-German rivalry which over-rode that of Anglo-French rivalry
