It was only in the second half of the 20th century that the term came to be used with any frequency, now mostly referring to the cultural flourishing of science and mathematics under the caliphates during the 9th to 11th centuries (between the establishment of organised scholarship in the House of Wisdom and the beginning of the crusades), but often extended to include part of the late 8th or the 12th to early 13th centuries.
Tek u drugoj polovini 20. veka termin je počeo da se značajnije koristi, i sada se uglavnom odnosi na kulturni procvat nauke i matematike pod kalifatima tokom perioda od 9. do 11. veka (između uspostavljanja organizovane stipendije u Kući mudrosti i početka Krstaških ratova), mada se često proširuje tako da obuhvata deo kasnog 8. ili 12. do ranog 13. veka.
