One of Wilhelm's diplomatic blunders sparked the Moroccan Crisis of 1905, when he made a spectacular visit to Tangier, in Morocco on 31 March 1905. He conferred with representatives of Sultan Abdelaziz of Morocco. The Kaiser proceeded to tour the city on the back of a white horse. The Kaiser declared he had come to support the sovereignty of the Sultan—a statement which amounted to a provocative challenge to French influence in Morocco. The Sultan subsequently rejected a set of French-proposed governmental reforms and invited major world powers to a conference that advised him on necessary reforms.
