From 1942 until 1965, Initiatives of Change, then known as Moral Re-Armament (MRA), had a significant presence on Mackinac Island in Lake Huron, Michigan USA. Summer conferences were held each year, leading to the construction of a purpose-built conference centre. Later, as MRA increasingly used plays and film to convey its message, a theatre and film studio were added.
