Tilaurakot is the capital of ancient Kapilvastu. it is important from historical as well as architectural point of view. The ancient story states, once the sons of AKOoka, king of Kausal Rajya, happened to reach the ashram of Rishi Kapilmuni. They revealed their identity to the Rishi and he advised them to clear the nearby Saal forest and build residency. The place was called Kapilbatthu and later, people started calling it Kapilvastu. since they cleared Saal forest, they were named Shakya. The pages of history comments that king Akoka sometimes called his people Shakya. Thus, the Shakyas dynasty prevailed. Radhakumud Mukherjee mentions that Shakya dynasty had about 80,000 residents. When Bidrukh assassinated, there were 77,000 Shakyas, reckons Rakhil. Archaeologists found that Shakyas were outstanding in kalas and architectural designs. The archaeological structures date back to 11th century. The first king of Kapilvastu was Ulkamukh and 8,210 generations later, the dynasty was led by Dhandurga or Jayasen, grandparent of Buddha. When Suddodhan ruled, peace and harmony was maintained in Kapilvastu. King Suddhodhan married Mayadevi, princess of Ramgram. So the two nations had better relation. Ruling period of king Suddhodan is considered the golden period for Kapilvastu. In that period, the Rajdurbar, Bihar, Stupas, trade and art flourished. After Siddhartha left the kingdom, Kind Suddhodan looked after the kingdom. When Siddhartha visited Kapilvastu, the people and royal members were also influenced by Buddhist teachings. During the 6th century, Kapilvastu was famous for its cultural aspects. Samrat Ashoka visited the place twice and indicated the birthplace of Kanakmuni, Krukuchhanda, Siddhartha by building three pillars. Brahmalipi is inscripted in two of these pillars which have really helped in the historical and archaeological studies.
