Barotseland was never a separate colony. There was no governor at Lealui. The Independence of Zambia would have gone ahead with or without the Barotseland Agreement.
FUrthermore the Lozis have subjugated the Mbunda, Kwangwa, Nkoya, Chokwe, Luvale and Lunda mistreated them and considered them slaves.
The lack of development in Western Province can be laid down at the discriminatory and retrogressiva and aggressive tribalism of the Lozis. 48 years after Independence nd is next to impossible for a non Lozi to:-
1. Own land
2. Be Provincial Minister or Permamnent Secreatary
3. Invest and operate a business
Secondly the Barotseland they claim is a figment of their imagination with places like Lusaka Kabwe, Chingola, Solwezi etc which never were under Lozi control. This Barotseland nonesense is the creation of raw naked tribalism and egomaniacal dreamers who long for an imaginary Lozi dominated state where a few Lozi aristocracts lord it over their Mbunda, Manyengo, Kwangwa, Nkoya, Chokwe, Luvale and Lunda slaves.
