Australia-born Christchurch shooter Brenton Harrison Tarrant 's manifesto '' The Great Replacement '' named after the French far-right theory of the same name quoted Pope Urban II ( who ordered The First Crusade ) and his speech demanding the retaking of Jerusalem , the death of 11-year-old Swedish girl Ebba Akerlund , NATO involvement in Kosovo , a desire to retake Istanbul ( aka Constantinople ) from Turkey to have in Christian hands and the motives listed was in his own words revenge against Islam . The shooter 's rifles were covered with white supremacist symbols and names of various historical figures and battles between Muslims and non-Muslims such as Charles Martel and Skanderbeg as well as the Battle of Tours in 732 and Battle of Vienna in 1683
