The Second Pandya Empire ruled parts of southern India between 1000-1700 CE. A key ruler was Jatavarman Sundar Pandyan I who expanded the empire through military campaigns defeating the Cheras, Hoysalas, Cholas, and gaining control of Sri Lanka in the 13th century. However, internal succession struggles and invasions by the Delhi Sultanate led by Malik Kafur in 1311 CE greatly weakened the empire. The Pandya kingdom was divided and their control over the Tamil region declined significantly, coming to an end around 1700 CE.
