Hospitallers. A celebrated brotherhood founded at various times and in different countries for the care of the sick in hospitals.

One of the earliest recorded instances of a hospital served by such a brotherhood is that of Constance, in the 13th century. See [Saint John of Jerusalem] and [Teutonic Knights].

Hostages. Are persons given in pledge for the performance of conditions. When a town capitulates, victors and vanquished usually give into the custody, one of the other, several officers, as pledges that each party will duly carry out the terms stipulated. When the terms are fulfilled, the hostages are exchanged; but if the terms be evaded, the opposite side holds the right to put to death, or otherwise punish, the hostages in its possession; of late years the practice is going out of use.
