The First Moroccan Crisis or the Tangier Crisis was an international crisis between March 31 1905 and April 7 1906 over the status of Morocco. Germany wanted to challenge France's growing control over Morocco, aggravating France and Great Britain. The crisis was resolved by the Algeciras Conference of 1906, a conference of mostly European countries that affirmed French control; this worsened German relations with both France and Britain, and helped enhance the new Anglo-French Entente.

Bernhard Heinrich Karl Martin, Prince of Bülow was a German statesman who served as the chancellor of the German Empire and minister-president of Prussia from 1900 to 1909. A fervent supporter of Weltpolitik, Bülow devoted his chancellorship to transforming Germany into a global power. Despite presiding over sustained economic growth and major technological advancement, his government's foreign policy did much to antagonize France and Great Britain, which contributed significantly to Germany's defeat in the First World War.
