For non Cameroonians: when we refer to Southern Cameroons or Northern Cameroons these are territory names both located in West Cameroon.

S. Cameroons and N. Cameroons administered by British w/ Nigeria. S. Cameroons now in Cameroon as SW and NW regions. N.Cameroons in Nigeria

Many still refer to SW and NW regions under the original Southern Cameroons even though it’s in the West and not the South.

N. Cameroons is now in Eastern Nigeria in Adamawa State.

So if you’re not confused you might not get it.

Territory known as Eastern Cameroons became la Republique du Cameroun Jan 1 1960. S.Cameroons and N.Cameroons gained independence Oct 1 1961

By vote (fairness can be debated but they voted)Southern Cameroons joined la Republique du Cameroun to form the Federal Republic of Cameroon

Northern Cameroons voted to become independent by joining Nigeria.

Again, people will say vote wasunfair. But no Northern Cameroons movement today. Southern Cameroons movement aka anglophone movement active

This explains the significance of the October 1 date for Southern Cameroonians. Not just Nigeria.

Many Nigerians, not just francophone Cameroonians never knew that N. Cameroonians are part of Nigeria since 1961.
