Explanation:

Rajadhiraja1 performed the Ashwamedha sacrifice,and Rajendra annexed the whole of SriLanka. And took title of Gangaikonda.

At local government level, every village was a self-governing unit. A number of villages constituted a larger entity known as a Kurram, Nadu or Kottam, depending on the area.A number of Kurrams constituted a valanadu.These structures underwent constant change and refinement throughout the Chola period
Land grants to religious institutions were called Brahmadeya, (i.e. donated to Brahmins) Devadana (donated to Gods) and Agrahara (Settlement – of priests) These lands donated to the temples and monasteries apart from being used as normal tenancy also carried a right vested with the temple authorities to call for unpaid labour (called Vishti) as a religious service to the temple from the tillers on the donated land.

Lands were given as brahmadeya either to a single Brahmana or to several Brahmana families which ranged from a few to several hundreds or even more than a thousand, as seen in the South Indian context. Brahmadeyas were invariably located near major irrigation works such as tanks or lakes. Often new irrigation sources were constructed when brahmadeyas were created, especially in areas dependent on rains and in arid and semi-arid regions. When located in areas of intensive agriculture in the river valleys, they served to integrate other settlements of a subsihena level production. Sometimes, two or more settlements were clubbed together to form a brahmadeya or an agrahara. The taxes from such villages were assigned to the Brahmana donees, who were also given the right to get the donated land cultivated. Boundaries of the donated land or village were very often carefully demarcated. The various types of land, wet, dry and garden land within the village were specified. Sometimes even specific crops and trees are mentioned. The land donations implied more than the transfer of land rights. For example, in many cases, along with the revenues and economic resources of the village, human resources such as peasants (cultivators), misans and others were also transferred to donees. There is also growing evidence of the encroachment of the rights of villagers over community lands such as lakes and ponds. Thus, the Brahmanas became managers of agricultural and artisanal production in these settlements for which they organized themselves in to assemblies.
