Mahasena vs Vasabha

Mahasena, influenced by the teachings of the monk Sanghamitta, suppressed Theravada Buddhism and destroyed several temples, including the Mahavihara in Anuradhapura. This action caused a schism in the Buddhist community and led to a period of religious conflict.

Mahasena constructed the Minneriya tank, one of the largest irrigation reservoirs in Sri Lanka. The tank, with a circumference of over 20 miles, provided water for agriculture in the dry zone, significantly boosting rice production and supporting a large population.

Mahasena built the Kavudulla tank, another major irrigation reservoir in the North Central Province. This tank, along with Minneriya, formed part of a network of reservoirs that transformed the dry zone into a productive agricultural region.

Mahasena constructed the Giritale tank, a large irrigation reservoir near Polonnaruwa. This tank further expanded the irrigation network in the dry zone, demonstrating Mahasena's focus on water management and agricultural development.

Later in his reign, Mahasena reversed his anti-Buddhist policies and restored the Mahavihara. He also built the Jetavanaramaya, a large stupa in Anuradhapura, which became a major center of Buddhist worship.

Vasabha founded the Lambakanna dynasty after overthrowing the previous ruler, Subharaja. He established a new line of kings that would rule Sri Lanka for several centuries, marking a significant shift in the island's political landscape.

Vasabha expanded the borders of the Anuradhapura kingdom through military campaigns, bringing more territory under his control. He consolidated his rule and strengthened the kingdom's defenses against external threats.

Vasabha constructed numerous irrigation tanks and canals across Sri Lanka, including the Mahavilachchiya tank and the Alahara canal. These works improved agricultural productivity and supported the growth of the Anuradhapura kingdom.

Vasabha constructed the Mahavilachchiya tank, one of the largest irrigation reservoirs in ancient Sri Lanka. The tank stored water for irrigation and helped mitigate the effects of drought in the region.

Vasabha built the Elahara Canal, a major irrigation channel that diverted water from the Mahaweli River to the dry zone. The canal supported rice cultivation and helped sustain the population of the Anuradhapura kingdom.
