During the 18th and 19th centuries it received an influx of rabbis who re-established it as a center for Jewish learning.

Around 600 people, including nearly 500 Jews, died when the town was devastated by the 1837 Galilee earthquake. An American expedition reported that Tiberias was still in a state of disrepair in 1847/1848. Rabbi Haim Shmuel Hacohen Konorti, born in Spain in 1792, settled in Tiberias at the age of 45 and was a driving force in the restoration of the city.
