The city was the first of it's kind with well designed sanitary system, Gardens, Irrigation and Water supply systems, Temples, cemeteries and burial grounds, etc. The city was then became the capital city of Sri Lanka and flourished under many subsequent Kings ruled for centuries.

Anuradhapura Kingdom was highly vulnerable to invasions from South India and suffered usurp of throne several times, by invading Kings from south India. Singhalese Kings have managed to defeat the invaders after reorganizing the troops, although the invading kings ruled in the mean time. One such historic battle held Between King Dutugamunu and South Indian King, Elara. In that, King Elara was defeated and King Dutugamunu ruled the country in single sovereignty.

The Anuradhapura Kingdom was under constant threat from south Indian kingdoms. The King Mahinda V ascended to throne in 982 A.C, and was the last Sinhalese king to rule the country from Glorious city. At this time the South Indian realm Chola, became very powerful under the Great Rajaraja (985- 1018 A.C) and conquered Sri Lanka. The King Mahinda was captured and imprisoned in South India.

The South Indians ruled the country for next 75 years. They shifted the Capital city to Polonnaruwa due to strategic reasons after considering the vulnerably for attacks from both native Sinhalese people and other south Indian Kingdoms.
