Sri Lankan kings ruled the island of Sri Lanka for centuries, establishing powerful dynasties that shaped its history. The most notable among them were the Anuradhapura and Polonnaruwa kingdoms, which thrived from the 3rd century BCE to the 13th century CE. These kings were known for their contributions to Buddhism, architecture, and irrigation systems, which supported agriculture. The kings often engaged in conflicts with foreign invaders and rival kingdoms, such as the Chola dynasty from India. They also promoted trade and cultural exchanges, leading to a rich heritage that includes ancient temples, stupas, and inscriptions. The legacy of these kings continues to influence Sri Lankan culture today.
