The Palakkad Pass, a low mountain pass nestled in the Western Ghats also known as the Pashchima Ghat or the Sahyadri Mountains between Coimbatore district in Tamilnadu and Palakkad district in Kerala, is a marvel of nature. Spanning approximately 24-30 km in width, this geographical wonder separates the towering Nilgiris and Anamalai hills, both rising over 2,000 meters above sea level, with an elevation of 140 meters. The Palakkad Pass has played a pivotal role in shaping the region’s history, from being a conduit for ancient trade to serving as a critical transportation route today. Let’s delve into the origins of the Palakkad Pass, its significance in trade and history, and its relevance in the present day.
Numerous theories surround the origin of the Palakkad Pass. Dating back to prehistoric times, the pass’s formation involved geological processes such as shearing and erosion. One hypothesis suggests that the gap was formed by landslides due to rivers flowing in opposite directions. Additionally, some geologists believe that the gap resulted from the drift of continental shelves after the separation of Australia and Africa from the Gondwana landmass. This region, about a 100 million years ago, was once connected to Madagascar’s Ranotsara Gap in the Angavo Mountain. There’s evidence of distinct flora and fauna that share the same geological likeness to that of the Ranotsara Gap which can still be seen today. Two French geologists, Yuri Gunnell and David Harbour proposed this theory in their research paper, published in 2008. Rare and endemic species of birds such as the Tufted Duck, Red Spurfowl and even a threatened species called the White-Bellied Shortwing and about 450 types of trees that have survived hundreds of years have also been found. The vegetation of this area is considered dry evergreen forest.
The Palakkad Pass has been a crucial passage for trade and cultural exchange for thousands of years. Around 3000 BC to 40 AD, Arab traders dominated the Indian Ocean trade zone and used the Palakkad Gap to facilitate trade between South India and the Arabian Peninsula. Roman trade with India began in the 1st to 2nd century CE, with spices and gems being the primary commodities exchanged. The Palakkad Gap served as a vital connection between Kerala and Tamil Nadu during this flourishing trade period. Handicraft works, emeralds, glass and more were sent to the ancient Muziris Port on the western coast through the Palakkadan pass to then be sent to the west. The bead specialist Peter Francis, has stated that these crafts were sent from Kodumanal to Ponnani through this pass also. Without this connection there wouldnt be any intercultural exchange or trade between these two states. This pass is a significant part of South India’s vibrant trading history.
In the 18th century, the Palakkad Pass gained importance during the colonial era when Kerala was invaded for the first time in history by Mysore Sultans- Hyder Ali and Tipu Sultan. The British East India Company eventually took control of the region after several Anglo-Mysore Wars. The Palakkad Pass played a significant role in military campaigns and was considered a key gateway between the east and west coasts of South India.
