Foundation of the Afrikaner Confederation (October, 1740 AD)-The recent invasion of the Free State by Rharhabe in the aftermath of Scots-Irish/Afrikaner squabbles reveals just how fragile the situation has become. Representatives of the various white ethnicities (and one or two Coloureds as well—high-caste Indians) come to Cape Town and hammer out a new constitution. Slavery, which the white ruling class recognizes as untenable in the long term and a standing internal threat due to the recent slave risings, is also abolished. The proposal to abolish slavery (with compensation for masters) was a major kink in the reorganization process—Biblical debate raged for days before the anti-slavery forces won (the leader of that faction pointed that although slavery may be Biblical, it is not mandatory, and if the “powers that be” outlawed slavery, it would be immoral). Mechanisms will be put in place to exploit blacks economically—“hut taxes” to make previously self-sufficient black communities (untouched by slavery) need money to pay and thus need to work for whites, reparations in cash and labour from the followers of (the warlord) the carnage caused by the recently-concluded war, and limits to the size of tribal cattle herds (ostensibly for environmental reasons, but in reality to keep the tribes from supporting themselves, thus requiring them to work for Afrikaners). An apartheid-like policy is put in place where newly-freed slaves are NOT considered legal residents of the white settlements, but of the places where they (or their parents or grandparents) were taken as slaves. Thus, they’re subject to legal controls of various kinds. The state church is legally separated from Holland and becomes the Afrikaner Reformed Church. It is made the official religion and one must be a member in order to have a government position or own land larger than (what amount?). Other Protestant churches have complete freedom of religion, while Catholics, Hindus, and Muslims are subject to restrictions of various kinds (no attempts to convert Calvinists, must apply for permission to expand buildings, etc). The harshest restrictions are on Catholics, since the Afrikaners fear the Catholic states of Europe.
By now you could have lots of Sikhs in the army. I'd wonder if the Sikhs would be granted freedom of religion since they were the 'protestants' of India.
