The term 'middle post-medieval' is not used, and there is debate as to what constitutes the late post-medieval period. For the 18th century, it is best to stick simply to 'post-medieval' and qualify it using calendar dates.</p>0115001800120572016-08-22 09:10:3111562016-08-22 10:10:46239NINETEENTH CENTURY<p>Period between the end of the Post-Medieval period and the Modern period.</p>0362180119001000602016-08-31 13:34:3811562016-08-22 10:11:02241MODERNMOp0gjgrsgn960119012050125622016-08-22 09:10:4711562016-08-22 10:11:022
