In 1918 Austria Hungary annexed Bosnia following a rebellion in Turkey which made their empire stronger and bigger. Serbia, which was an ambitious but a small country, was too weak to defend itself. Nevertheless, they were determined to triumph. Fortunately, Russia opposed to it as it wanted al Slavic people to be liberated and was extremely annoyed at Austria Hungary for acting without informing them.
This crated a chance for a potential rebellion to rise as Russia, the strongest out of the three, is ready to support Serbia. Therefore, Germany intervened and decided to help Austria Hungary which crushed Serbia’s hopes of reunion as Russia felt inferior and too fragile to fight both the countries especially with France and Britain’s refusal to assist. Consequently, the tension in Europe was raised significantly as Serbia was annoyed at Russia. Consequently this raised the tension in Europe significantly as Serbia was annoyed at Russia for withdrawing help and was more determined to oppose Austria Hungary. Russia, on the other hand, was absolutely humiliated and it was determined not to repeat this. As a result they decided to enhance the army and seek for revenge. This Russia France and Britain closer together because of the mutual hatred for Germany
In 1915 France wanted control of Morocco which was one of few regions in North Africa that wasn’t controlled by a European power and as per Entente Cordiale. Britain had to support them. However, Germany decided to oppose France to test Entente Cordiale and expand its own empire and it already had the strongest army. Kaiser rode to Tangier and convinced everyone to attend a conference to discuss Morocco’s future. In the end, France won and gained joint control of morocco police. This event not only angered France and Britain and made them more concerned and suspicious of Germany’s intentions but also began secret military talk between them whereas Germany were felt deeply humiliated.
The consequences of the 2nd Moroccan crises were even more devastating. When Germany, determined not to lose again, send a gunboat to the port of Agadir to oppose France who send an army to help the ruling sultan stop an rebellion in 1911, this action was perceived as warlike by several countries. Germany was again left mortified which meant it was unlikely to back down in any future crises. Furthermore, German people were extremely annoyed at Britain for supporting France and supported the idea of war where as Britain became completely convinced that Germany wanted to dominate Europe and therefore made a new secret naval agreement with France.
I believe the Moroccan crises increased the tension in Europe considerably more than the Bosnian crises as the Agadir crises was far more dangerous than the previous Bosnian and Moroccan crises; it had bought Europe to the brink of war as preparation for war had begun in all 3 countries. Furthermore, whilst the Bosnian crises, only involved 3 European powerhouses, everyone was involved in the First morocco crises. Although the Bosnian crises had Russia humiliated, during the Moroccan crises, Germany was far more disgraced and angering Germany is noticeably more lethal than angering Russia as Germany ambitions, sense of honour and power surpass those of Russia’s. In addition, Moroccan crises destroyed British- German relationship severely and made Britain more likely to enter war against Germany.
