Incorrect Statement: It was a British colony.

Nagaland was not a British colony during Angami Zapu Phizo's activism. It was a part of India.

Angami Zapu Phizo (1904-1990) was a prominent figure in the movement for an independent Nagaland. He served as the president of the Naga National Council and initiated an armed struggle against the Indian state. Following this, he went into hiding, residing in Pakistan, and eventually spent the last three decades of his life in exile in the United Kingdom.
