The Zanzibari War of Independence was an armed conflict fought between Ireland and the people of its colony of Irish Africa from September 1945 upon the declaration of independence by the Congress of Tribes and the April 1947 peace accords that allowed for independence. The war was notable for its brutality, in which Irish soldiers allegedly violently massacred entire villages, turning public opinion sharply against the colonial government. The war also featured white English transplants fighting alongside black natives, leading toward the amicable relationship between European immigrants and black natives in the following decades.
