Church restrictions on bodies: it was sinful for a person to be without clothing in front of an artist. To create realistic paintings, corpses were used.
Corpses were used as a model for the human body. Renaissance painters strove for realism and the corpse provided a realistic human image. An alive person would not be able to pose, in particular without clothing, for a painter. This would have been sinful.
Sorry to say there is no image
If by South Africa you are referring to the Republic of South Africa, then their transition to Democracy was a bit rocky. It was a part of the British empire before they gained their independence as a free republic. This free republic however was not a democratic one due to things like apartheid rules where a minority of rich people who were mostly white controlled the government at the expense of the local African majority. As the fight for democracy continued many things started coming up like huge unemployment and infringement of human rights. Apartheid ended and currently the country is a democracy with suffrage, but there is evidence of high corruption among the government employees and the administration. Expand those ideas into an entire essay.
