Spanish demarcación, from demarcar, to mark boundaries : de-, off (from Latin dē-; see de-) + marcar, to mark (from Italian marcare, from Old Italian, of Germanic origin; see merg- in Indo-European roots).(American Heritage® Dictionary of the English Language, Fourth Edition)
First recorded c.1752, from Spanish linea de demarcacion and/or Portuguese linha de demarcação, the demarcation line laid down by the Pope on May 4, 1493, dividing the New World between Spain and Portugal on a line 100 leagues west of the Cape Verde Islands. Both derive from demarcar, from de- + marcar ("to mark"), from Italian marcare, from the Germanic root of march. (Wiktionary)
