Kruċjata
Il-Kruċjati kienu serje ta' bosta kampanji militari—normalment sanzjonati mill-Papat—li seħħew bejn is-Seklu XI u s-Seklu XIII. Oriġinarjament, kienu Gwerrer Sagri Kattoliċi bl-iskop li terġa' tintrebaħ Ġerusalem u l-Art Imqaddsa minn taħt il-ħakma Musulmana, iżda xi wħud kienu indirizzati lejn Ewropew oħra, bħall-Kruċjata Albiġeżjana kontra l-Katari tan-nofsinhar ta' Franza u l-Kruċjati Nordiċi.  Ir-Raba' Kruċjata kienet oriġinarjament intiża li tilħaq l-Art Imqaddsa, iżda ġiet ridiretta mill Venezjani kontra Konstantinopli.
