The face of radical Islamism has rocked headlines in recent months, demonstrating to the world the threat it poses to Islam’s own cultural heritage.

Many were shocked when spiritual leader Said Efandi al-Chirkawi was killed in a suicide bombing in the tiny Russian Republic of Dagestan by a woman pretending to be one of his students. Nearly 100,000 mourners attended the funeral of the revered cleric, who had been working to bring peace between warring Islamic factions. This was the second such spiritual leader in this remote region to have been killed by radical Islamists in the past year alone.

Elsewhere, in Libya, Mali, Pakistan and Egypt, attacks are also on the rise. Militants around the world are leading a two-pronged assault by targeting outspoken Muslim leaders who denounce violence and by destroying ancient shrines and cultural sites that are respected by Muslims and non-Muslims alike. In recent years, the Taliban’s systematic assassination of moderate Afghan clerics, and their destruction of the sixth-century Buddha statues in 2001, are classic examples of how radical Islamists use terror tactics to solidify their power. This blatant disregard for diverse faith and cultural traditions has grave implications for global security.

When pluralistic social norms are eliminated, it paves the way for hardline forces to rise. Nowhere is this trend more apparent than across Africa, where militants are fueling sectarian and community conflict. Earlier this year in Mali, Islamists of the Ansar Dine organization initiated a campaign to systematically obliterate cultural sites in Timbuktu, including 16 mausoleums of ancient Muslim saints. Many of those cultural sites had recently been put on a list of endangered World Heritage Sites by UNESCO. In late August 2012, armed Salafis in Libya attacked the tomb of Abdel Salam al-Asmar, a 15th-century Muslim scholar who was highly regarded by locals. Nearby in the city, militants also set fire to a historic library, burning centuries of rare academic and religious resources to the ground.
