Jayasthiti Malla, with whom commences the later Malla dynasty of the Kathmandu Valley, began to reign at the end of the 14th century. Though his rule was rather short, his place among the rulers in the Valley is eminent for the various social and economic reforms such as the 'Sanskritization' of the Valley people, new methods of land measurement and allocation etc. Yaksha Malla, the grandson of Jayasthiti Malla, ruled the Kathmandu Valley until almost the end of the 15th century. After his demise, the Valley was divided into three independent Valley kingdoms.Kathmandu, Bhaktapur and Patan.in about 1484 AD. This division led the Malla rulers into internecine clashes and wars for territorial and commercial gains. Mutually debilitating wars gradually weakened them, that facilitated conquest of the Kathmandu Valley by King Prithvi Narayan Shah of Gorkha. The last Malla rulers were Jaya Prakasha Malla, Teja Narasingha Malla and Ranjit Malla of Kathmandu, Patan and Bhaktapur respectively.
