Answer
The Blasphemy Acts, under which Aikenhead was prosecuted, were a series of laws enacted in Scotland between 1695 and 1825 that made it a crime to speak or write anything considered blasphemous, profane or contemptuous of God or religion. These acts were used to suppress religious dissent and punish those who held unorthodox beliefs, and Aikenhead's prosecution was a notable case of their enforcement.
