Kulaba (also spelled Kolaba) district was split from
Thane district in 1869. At this point, the northernmost parts of present-day Raigad district were retained in
Thane district. Panvel, just across the bay from
Mumbai, was not included in Kolaba district until 1883, and
Karjat, an area in the north-east corner of modern Raigad district, was not placed in Kolaba district until 1891. Kolaba district was later renamed as Raigad district. In July 2023, a major
landslide, caused by torrential rains, resulted in at least 22 deaths, with more than 100 feared trapped under debris. Over half of the houses in the hillside village, precisely 17 out of 48, were either entirely or partially buried by the debris from the landslide. ==Geography==
