The former Eastern Region was proclaimed a sovereign nation, Biafra by Odumegu Ojukwu on

Explanation

The question is asking when the former Eastern Region was declared a sovereign nation called Biafra by Odumegu Ojukwu. The options are May 30, 1967 (Option A), June 15, 1966 (Option B), April 6, 1968 (Option C), January 10, 1965 (Option D), and April 21, 1969 (Option E). The correct answer is Option A, May 30, 1967.

To provide some context, the former Eastern Region was a region in Nigeria that was predominantly inhabited by the Igbo people. In the 1960s, there were tensions between the Igbo people and other ethnic groups in Nigeria, which eventually led to a military coup in January 1966. The coup was led by mostly Igbo officers, and it was seen as an Igbo-led coup. Following the coup, there were reprisal killings of Igbo people in other parts of Nigeria.

In May 1967, Odumegu Ojukwu, who was the military governor of the Eastern Region at the time, declared the region as a sovereign nation called Biafra. This was in response to the perceived marginalization of the Igbo people in Nigeria and the violence against them. The Nigerian government did not recognize Biafra as a sovereign nation and a civil war broke out between Nigeria and Biafra. The war lasted for three years and resulted in the deaths of millions of people, mostly from the Biafran side.

In summary, the correct answer to the question is Option A, May 30, 1967, when the former Eastern Region was declared a sovereign nation called Biafra by Odumegu Ojukwu in response to the perceived marginalization of the Igbo people in Nigeria.
