IVU is a growing global network of independent organizations which are promoting veg'ism worldwide.
IVU was founded in 1908 in Dresden, Germany. The idea came from the French Vegetarian Society, the first Congress was organised internationally by the British Society and locally by the Dresden Society with support from the Deutsche Vegetarier-Bund. Since then a series of World Veg Congresses have been held on most continents and, in 2008 IVU returned to Dresden for the Centenary 38th Congress. From 2012 this major global event has been renamed the 'IVU World Vegfest'.
