THIS WILL HELP YOU

Explanation:

Ashoka waged a destructive war against the state of Kalinga (modern Odisha),[7] which he conquered in about 260 BCE.[8] He converted to Buddhism[7] after witnessing the mass deaths of the Kalinga War, which he had waged out of a desire for conquest and which reportedly directly resulted in more than 100,000 deaths and 150,000 deportations.[9] He is remembered for the Ashoka pillars and edicts, for sending Buddhist monks to Sri Lanka and Central Asia, and for establishing monuments marking several significant sites in the life of Gautama Buddha.[10]
