## History

Ariyalur is one of the most important places for the Chozha Dynasty. Vallavarayan Vandhiyadevan home town is Ariyalur. The late Cholas made Gangai Konda Cholapuram as their capital.
After the Chozha dynasty, Vijayanagar Nayak kings ruled and built many temples in Ariyalur Kothandaramar temple.
In 1741 the Marathas invaded Tiruchirappalli and took Chanda Saheb as captive. Chanda Saheb succeeded in securing freedom in 1748 and soon got involved in a famous war for the Nawabs place in the Carnatic against Anwardeen, the Nawab of Arcot and his son Mohammed Ali.
Mohammed Ali annexed the two palayams of Ariyalur and Udayarpalayam located with troops were in the Ariyalur district on the grounds of default in the payment of Tributes and failure to assist him in quelling the rebellion of Yusuf Khan. In November 1764, Mohammed Ali represented the issue to Madras Council and obtained military assistance on 3 January 1765. The forces led by Umdat-Ul-Umara and Donald Campbell entered Ariyalur and captured it. The young Poligar together with his followers thereupon fled to Udayarpalayam. On 19 January the army marched upon Udayarpalayam. The Poligar's troops were defeated and the playams were occupied. The two poligars fled their town and took refuge in Tharangampadi, then a Danish Settlement. The annexation of the palayam gave the Navab uninterrupted possession of all his territories extending Arcot to Tiruchirapalli.
The history followed was a power struggle between Hyder Ali and later Tipu Sultan with the British. After the death of Tipu Sultan the English took the civil and military Administration of the Carnatic in 1801. Thus Tiruchirappalli came into the hands of the English and the District was formed in 1801.
