How did kaiser william 11 continue bismarck policies

Kaiser William II continued a few of them by adding social welfare programs, built up army and navy and Bismarck’s foreign policy was neglected

Explanation:

Bismarck was a Prussian office-bearer and also long served head of government of the German empire. He was successful in maintaining a peaceful foreign policy with Europe for two decades but his domestic policies were less popular. After William II Kaiser was formally coroneted to be the monarch of German empire, he asked old chancellor, Bismarck to step down from the office which led to his down fall.  

William II who was young and an ambitious monarch clutched the reins of the German foreign policy. He was considered to be a great king but not a skilled politician. William II considered Bismarck Foreign policies to be of a little value and adopted more aggressive and dynamic foreign policies in order to capture the attention of world politics.
