To what extent would you consider Bismarck to have been correct in pursuing this campaign. (I got 9/10)

Bismarck was correct in pursuing the KK because it reduced the threat of the Catholics taking over. 

However the Kk turned out to be quite a failure for Bismarck.

The KK was a success campaign because:

• Bismarck gained control over the Catholics.
• catholic schools were under supervision by the state.
• The govt had power to remove Jersuits.
• Prussia could suspend payments to Churches where Priests resisted new legislation, under the KK.
• 1000 Catholic Bishops were suspended and catholic weddings were no longer valid.

This proves that the Catholics were under greater control and the Protestants and German unity was now protected.

However, the KK was a failure for Bismarck because:

• It only upset the Catholics more.
• The KK caused opposition and Pope Puis IX's counter attack threatended to excommunicate those who obeyed the oppressive laws.
• Only 30/10,000 Catholic Priests submitted to new legislation which shows that most catholics supported the Pope over Bismarck.
• KK led to an increase in the Centre Party's strength, as they won 91 seats in the Reichstag in 1874. 
• Many Protestants disagreed with the KK as they though it was a threat to civil rights and undermined freedom of conscience. 
• This illustrates that the campaign was not supported by many Germans, so it did not work.#
• The KK increased disunity within the German Empire.

Bismarck was correct in pursuing the campaign as he was able to use the Centre Party's successful outcome of the KK, as a weapon against the growing threat of Socialism; the failure turned to his advantage.
