僧伽罗人以自己的雅利安人血统而感到自豪。根据他们的语言结构以及早期编年史中的神话,这种信念是有确切根据的。但是南印度诸王国的入侵以及随着达罗毗荼人的到来而进行的文化传播,使僧伽罗人一直处于达罗毗荼人的影响之下。这一点已经得到广泛的承认。直到十三世纪以前,僧伽罗文明的中心一直是在干燥地区,即岛的北部中区和东南部。十一世纪和十三世纪泰米尔人的入侵可能促使了这些中心向岛的南部和西部湿润地区的迁移。但是向西南迁移并非仅仅由于诸如外来军事入侵以及古代僧伽罗诸王国主管农业灌溉系统机构的衰败所引起的“推动因素”所致。僧伽罗人日益增强的控制热带雨林的能力、西南部自然资源(特别是椰子、槟榔和肉桂)的价值以及依靠雨水浇灌稻田的条件,可能也是这种迁移的重要原因。所谓“牵引因素”正是这些。在大规模泰米尔入侵之前,自十世纪左右开始,西南地区人口就有日益增加的迹象。在 Sinhalese are proud of their Aryan origin. This conviction is based on their linguistic structure and the myths of the early Chronicles. However, the invasion of South India’s kingdoms and the spread of culture with the arrival of Daruodua have kept the Sinhalese under the influence of Darussalam. This has been widely recognized. Until the 13th century, the center of Sinhala civilization had always been in dry areas, namely the northern and central parts of the island and the southeast. The invasion of Tamils ​​in the eleventh and thirteenth centuries may have prompted the relocation of these centers to wet areas in the south and west of the island. But the move to the southwest was not caused simply by “motivators” caused, for example, by alien military invasions and by the decay of institutions in charge of agricultural irrigation systems in the ancient Sinhalese kingdoms. The increasing ability of the Sinhalese to control the tropical rain forest, the value of natural resources in the south-western region, especially coconut, areca and cinnamon, and the conditions that rely on rainwater to irrigate rice fields may also be important causes of this migration. The so-called “traction factor” is exactly this. Prior to the massive Tamil invasion, the population in the south-west has been on the rise since around the tenth century. in
