INFLUENCE OVER KATHMANDU VALLEY
In fact, Taleju Bhavani (Nepali: तलेजु भवानी) worshiped as the family deity by Malla Kings of Kathmandu Valley is also the same family deity worshipped by Kings of Karnataka. Deval Devi(Nepali: देवलदेवी), the queen of Hari Singh Deva while entering into Kathmandu Valley as a refugee also brought a vase(Nepali:कलश) of Taleju Bhavani with her.
The influence of Karnataka on the Valley increased after Deval Devi and his son Jagat Singh (Nepali: जगत सिंह) entered the valley which was natural too. After the death of Hari Singh, the joint rule of Rudra Malla(Nepali:रूद्र मल्ल) and Ari Malla(Nepali:अरि मल्ल) kept going on. However, Ari Malla was just a name of ruler by name. Rudra Malla, after the death of Hari Singh Deva, gave refugee to the queen Deval Devi and her son Jagat Singh in his own palace. Deval Devi set/established the vase of Taleju Bhavani in the court/palace. After then, the later rulers of Nepal also became worshipers of Taleju Bhavani.
