"Part 1 contains the biographical details of all known rulers of the historical states of the Classical Age. The Parts 2 to 4 are arranged by continent. They begin, chronologically, in the early Middle Ages and continue up to our times. In addition, the appendix of the current Volume 4/2 contains the leaders of current active international organisations, e.g. the UN, the African Union, the FAO and the World Bank – including all presidents and commissioners of the European Union (or the EEC or EC) since 1958. The parts 1 to 4 are now finished. On account of its unique wealth of material, this all-round historically conceived compendium is an internationally recognised reference work. In all the historically orientated disciplines, it ranks among the fundamental tools of the trade." <link http: www.lub.lu.se cgi-bin ipchk www.degruyter.com viewbooktoc product>Regents of Nations : Part 1 Antiquity worldwide
