Official reconciliation between Lutherans and Mennonites began during the 450th anniversary of the Augsburg Confession in 1980. It led to a process of working through the painful legacy of persecution of Anabaptists, whom Mennonites regard as their predecessors, in the 16th century. Lutherans and Mennonites continue to build on the process of reconciliation that resulted in the 2010 action of Lutherans asking forgiveness for the persecution of Anabaptists by their ancestors in the 16th century.
