History of Kaikalur

The earliest human settlements near Kolleru were not permanent cities but fluid camps at the water's edge — communities that moved with the lake's seasonal shifts, fishing in the shallows, farming the temporary land when it emerged each summer. Archaeological hints suggest habitation near the lake shores long before recorded history, but no permanent civilisation — the lake made permanence impractical.

The Eastern Ganga dynasty of Odisha and later the Chalukyas understood something critical about this region: controlling Kolleru meant controlling irrigation, grain production, and the regional economy. Copper plates from this period show land grants in the Kaikalur area. The dynasties stationed forces here not to build a city, but to manage the water — who used it, who paid for it, who could be denied it.

Kolletikota stands as the most striking physical evidence of the region's medieval past. It was a fortified settlement on an island inside the lake itself — surrounded by water on all sides, naturally protected from land-based attack. The Langula Narasimha Deva Gajapati of the Eastern Ganga dynasty used it as a strategic administrative centre. Its design reflects an intimate understanding of the lake: the same flooding that threatened ordinary settlements became, for Kolletikota, a defensive moat.

During a conflict with Muslim rulers encamped at the nearby Chigurukota, enemy forces attempted to drain Kolleru by diverting the Upputeru channel — a move that would have destroyed the lake and collapsed the Gajapati defences. According to local tradition, a royal general sacrificed his daughter, Perantala Kanama, to invoke divine protection. The attempt to drain the lake failed. The channel was named after her. Her temple — known today as Peddintlamma — stands at Kolletikota and is still an active place of worship. The story is preserved not just in legend but in the name of the water itself.

The British period brought the single change that most altered Kaikalur's physical identity: the Vijayawada–Nidadavolu railway. The line, which passes through Kaikalur, transformed the town from a lakeside settlement into a transport node. Goods — primarily fish, rice, and later prawns — could now move quickly to Vijayawada and beyond. The town grew. A road network followed. National Highway 165, connecting Pamarru to Palakollu, established Kaikalur as a point on a longer journey rather than only a destination in itself.

After independence, Kaikalur was part of Krishna District before becoming part of the newly formed Eluru District. The aquaculture boom of the 1980s–90s brought significant economic growth but also triggered the environmental conflict around Kolleru that became a national case study. Today Kaikalur has a population of around 21,000, a literacy rate of 78.46% — above the national average — and an economy that still depends substantially on fishing, prawn farming, and agriculture.
