Without big farms to run, the people in the North did not rely on slave labor very much. In the South, the economy was based on agriculture. ... The North wanted the new states to be “free states.” Most northerners thought that slavery was wrong and many northern states had outlawed slavery.
The East India Company forced Sepoys to use new ammunition that went against their religious beliefs, hence causing the Sepoy Rebellion.
It all started when the British East India Company implemented the use of new bullets that must be coated with a mixture of pork and beef fat. This upset many Sepoy's, as several of them were Hindus and this went against their beliefs. Hindus belief that the cow is a sacred animal and are prohibited from touching or killing cows and eating beef.
Along with this, many Sepoys were also Muslim. In this religion of Islam, the pig is considered an unclean animal. This upset with the new policies caused a revolt of these Sepoys against the British East India Company.
