Today Islam is numerically the second largest religion in the world. Its message is aimed
generally at all people and has been addressed to Muslims and non-Muslims alike since the
beginning of Islam through the »Call to Islam« (Arabic däwa islamiyya). But what exactly does
»Call to Islam« mean? After a brief historical sketch of different forms of däwa this book
provides an overview of various däwa theologies of the 20th and 21st centuries as well as of
some däwa organizations and different däwa approaches. Finally the question is raised about
the challenges that däwa activities of a conservative or an Islamist Islam pose for liberal and
democratic societies.
