Why were the two crises important factors?

The Moroccan Crisis (1905-1906) was the first crises and was one of the long term causes of World War One. The fight over control of Morocco broke down the trust between the major European Powers. The second crisis was the Bosnian Crisis (1908-1909) and was caused by Austria-Hungary's desire to annex Bosnia-Herzegovina. This crisis led to the assassination of Franz Ferdinand which triggered the breakout of the war.
