The year stated in this question should be checked again and rectified.

Company rule came to an end in 1923 in Southern Rhodesia and settlers demanded for the end of company rule because they wanted effective self-government.

Explanation:

The settlers in Southern Rhodesia wanted self-government . This was because as the number of white settlers and elected members in the Legislative Council increased, there was a demand for self-government; a gradual transfer from Company rule to self-government took place.

In 1923 when the Company's charter was revoked by Whitehall, the Southern Rhodesia became a self-governing colony of Britain in that same year.

In 1924, the Northern Rhodesia experienced an end to British South Africa Company rule.
