Under an agreement between the Sri Lankan and Indian governments in the 1960s, around 40% of Hill Country Tamils were granted Sri Lankan nationality and many of the remainder were repatriated to India. However, the ethnic conflict has led to the growth of a greater sense of common Tamil identity, and the two groups are now more supportive of each other. By the 1990s most Indian Tamils had received Sri Lankan citizenship and some were not granted Sri Lankan citizenship until 2003.
