The regions of South Malabar and Kingdom of Cochin, both of which share a lot of historical, geographical, and cultural similarities, together constitute the districts of "Central Kerala". The Travancore region is incorporated in the districts of "South Kerala". The Travancore region was again divided into three zones as Northern Travancore (Hill Range) (Idukki and a smaller portion of Ernakulam), Central Travancore (Central Range) (Pathanamthitta, Alappuzha and Kottayam) and Southern Travancore (Southern Range) (Thiruvananthapuram and Kollam).
