The IGGP (International German Genealogy Partnership) was founded in 2015 by genealogy society leaders in the United States and Germany. The founding partners were Germanic Genealogy Society, Pommern Regional Group of MN, and Deutsche Arbeitsgemeinschaft genealogischer Verbände (DAGV). Although not one of the three charter partners of what was initially named the German American Genealogy Partnership (until November 2016), Palatines to America did participate in the initial online meeting on May 28, 2015 with fourteen individuals from the United States, Germany, and Poland.

On June 25, 2015, the Palatines to America national board of directors passed a motion to join the partnership thinking it would create new and valuable relationships in the world of German genealogical research that could benefit our society and its members.

Since then IGGP has grown tremendously and expanded far beyond its initial geographic boundary. As of early 2023 there are fifty-seven partner societies on five continents―Europe, North America, Australia, South America, and Africa. Counting the seventy-three member associations that are a part of DAGV in Germany, there are over one hundred twenty-five society partners.
