Aparanta
Aparanta, or Aparantaka (meaning "Western border") was a geographical region of ancient India. It corresponded to the northern part of the Konkan region on the western coast of India. English civil servant-turned-historian J. F. Fleet believed that the Aparanta region included Kathiawad, Kutch, and Sindh, beside Konkan. However, historical records make it clear that the extent of Aparanta was much smaller. The Junagadh inscription of Rudradaman mentions that during Ashoka's reign, a "Yonaraja" (literally; Ionian, or Greek, King), Tushaspha was the governor of Aparanta. A Buddhist text, the Mahavamsa states (xii.5) that at the conclusion of  the Third Buddhist Council (c.250 BCE), a "Yona" (Greek) "Thera" (monk) Dhammarakkhita was sent here by the emperor Ashoka to preach Dhamma and 37,000 people embraced Buddhism due to his effort ("Mahavamsa", xii.34-6). According to Buddhist scholar A.K. Warder, the Dharmaguptaka sect originated here. Aparanta is regarded as an umbrella term for "Shurparakadesha" for Konkan, to include in the North and Gomantaka in the south with the river "Kundalika" to serving as a dividing line in between the two.
