Answer:
Creating a division which was dedicated to sabotaging the government.
Step-by-step explanation:
Nelson Mandela expanded his anti-governmental activities in the 1960s by creating a division which was dedicated to sabotaging the apartheid regime. In 1961 Nelson Mandela became the commander in chief of the guerrilla army and became known as the black pimpernel. During this period he was able to learn how to fight and acquire weapons; however, in 1963 the police came across documents outlining the plans of the guerrilla army. This resulted in the arrest of Mandela and eight others where they were accused of sabotage and the conspiracy to overthrow the Apartheid regime. This led to the life imprisonment of Mandela through the Rivonia trial that established the central role of Mandela.
