In the latter Ottoman period, the city of Jerash's name was abandoned and changed to Sakib, yet this was not a permanent development, as the name "Jerash" reappears in Ottoman tax registers by the end of 16th century.
A strong earthquake in 749 AD destroyed large parts of Jerash, while subsequent earthquakes along with the wars and turmoil contributed to additional destruction. Its destruction and ruins remained buried in the soil for hundreds of years until they were discovered by German Orientalist Ulrich Jasper Seetzen in 1806. He began excavation and a return to life of the current Jerash by inhabitants of older villages. 70 years later, this was followed by the Muslim community, Circassians, who emigrated to Jordan from the Caucasus in 1878 after the Ottoman-Russian war. Subsequently a large community of people from Syria came to the area at the beginning of the 20th century.
