The first documented service that is akin to hospice care comes from the Crusades.
The Crusades were a series of religiously sanctioned military campaigns, called by the Pope and with the main goal of restoring Christian control of the Holy Land. Crusaders came from all over western Europe; the main series of Crusades occurred between 1095 and 1291.

The first hospices are believed to have originated in the 11th century when, for the first time, the incurably ill were permitted into places dedicated to treatment by Crusaders.
