My main goal for this talk is to describe Margulis's superrigidity theorem and how one can use a superrigidity type theorem to deduce arithmeticity of lattices. As such, I will review some basic examples of arithmetic lattices and then go on to discuss their general construction and the interaction between this construction and superrigidity. If time permits I will also try to highlight some of the ideas that go into the proof of superrigidity. No background on either will be assumed in the talk.
