On 31 October 1731 Archbishop Leopold Anton von Firmian of Salzburg ordered the expulsion of every Protestant from his archbishopric, more than 20,000 people by the surviving count. The order gave those with no land a single week to leave and householders two months, forcing a mass departure from a territory many families had lived in for generations.
Most of the expelled, roughly 16,000 to 17,000 of them, resettled in East Prussia at the invitation of Frederick William I, arriving at Konigsberg from May 1732 onward into a kingdom actively seeking Protestant settlers for its own territory. A far smaller group, some 300 people, took up a different invitation, from Britain's King George II, and crossed the Atlantic to settle in the new Georgia colony, founding the town of Ebenezer from 1734.
What this expulsion changed for Lutheranism's spread reached across an ocean from a single archbishop's order. The East Prussian resettlement rebuilt a displaced Protestant population inside another German speaking territory, but the smaller Georgia group tied the expulsion directly to Lutheranism's establishment in North America, a colonial foothold that traced its origin not to any deliberate missionary effort but to families expelled from Salzburg with as little as a week's notice.
