Tamil people
During the British Raj, the British combined all Tamil lands and gave them a new name, the Madras Presidency.  The Madras Presidency became a part of the British Raj.  Similarly, the British combined Tamil lands of Sri Lanka and other regions of Sri Lanka in 1802.  This became the Ceylon colony, also a part of the British Empire. When India became independent in 1947, Madras Presidency became a part of India.  Ceylon became independent in 1948, and the Tamil lands remained a part of independent Ceylon, now called Sri Lanka.
