The 52nd edition of the SIPRI Yearbook analyses developments in 2020 in security and conflicts; military spending and armaments; non-proliferation; arms control; and disarmament.

Analysing social change has too often been characterized by parochialism, either a Eurocentrism that projects European experience outwards or a disciplinary narrowness that ignores insights from other academic disciplines. This book moves beyond these limits to develop a global perspective on social change. The book provincializes Europe in order to analyse European modernity as the product of global developments and brings together renowned scholars from international relations, history and sociology in the search for common understandings. In so doing, it provides a range of promising theoretical approaches, analytical takes and substantive research areas that offer new vistas for understanding change on a global scale.

The evolution of the disarmament regime of the 1972 Biological and Toxin Weapons Convention (BTWC) is described from 1980, when the first BTWC Review Conference was held, until 1998. The author analyses the results of SIPRI's first four review Conferences.
